Embodiment 2 FIG. FIGS. 1 and 2 are the same as those in the first embodiment, and a description thereof will be omitted. FIG. 5 is a flowchart for controlling the relationship between the acceleration / deceleration setting time and the volume rotation angle by a control circuit used in the second embodiment in which the parameter changing device according to the present invention is used in an inverter device.

This routine is executed simultaneously with turning on the power. First, it is determined in step S5 that the power is to be turned on. If the power is not being turned on, this routine is exited. Step S
When it is determined in step S5 that the power is turned on, in step S6, the volume threshold Vxp of the acceleration time setting volume 7 and the volume threshold Vyp of the deceleration time setting volume 8 are read as the volume thresholds instructed at that time. That is, this is set as the initial setting value of the volume threshold value Vxp of the acceleration time setting volume 7 and the volume threshold value Vyp of the deceleration time setting volume 8. In step S7, an acceleration time setting volume 7 and a deceleration time setting volume 8 as volume thresholds
Is determined, and if not, a volume threshold value Vxp is set for the volume acceleration time setting value Vx and a volume threshold value Vyp is set for the deceleration time setting volume value Vy in step S9. When it is determined in step S7 that the acceleration time setting volume 7 and / or the deceleration time setting volume 8 as the volume threshold value has changed, the acceleration time setting volume value Vx and / or the deceleration time of the acceleration time setting volume 7 are determined in step S8. The deceleration time setting volume value Vy of the setting volume 8 is compared with the volume threshold value Vxp of the acceleration time setting volume 7 and / or the volume threshold value Vyp of the deceleration time setting volume 8. When it is determined in step S8 that the acceleration time setting volume value Vx and the deceleration time setting volume value Vy are smaller than the volume threshold value Vxp and the volume threshold value Vyp corresponding to the volume rotation angle θ, in step S10, the acceleration time setting volume value Vx is calculated. Parameters are set to the time setting volume value Vy by the volume acceleration time setting value Xx and the volume deceleration time setting value Xy. Step S8
, The acceleration time setting volume value Vx and the deceleration time setting volume value Vy become the volume threshold Vxp and the volume threshold Vyp
When it is determined that the value is not less than the predetermined value, the acceleration time setting volume value Vx is multiplied by a proportionality constant 10 in step S11 to obtain a volume acceleration time setting value Xx. The parameter is set as a volume deceleration time set value Xy by multiplication. The processing from step S7 to step S11 is to
This is performed until the second elapses.

As described above, the volume threshold Vxp and the volume threshold Vyp, which are the changing points of the acceleration time setting volume 7 and / or the deceleration time setting volume 8, are set to the values at power-on by the volume threshold Vx of the acceleration time setting volume 7.
p, the initial value of the volume threshold Vyp of the deceleration time setting volume 8 can be set. Of course, the value of the predetermined time immediately after turning on the power can be set as the initial value by setting the timer. In this type of parameter changing device, the change of the output characteristic corresponding to the displacement is performed based on the position of the acceleration time setting volume 7 and / or the deceleration time setting volume 8 at the time when the power is turned on. Since the output characteristics to be used are selected, when the position of the volume of the acceleration time setting volume 7 and / or the deceleration time setting volume 8 used last time is used, it can be used without being influenced by the characteristics. Therefore,
The proportionality constant of the parameter can be changed from an arbitrary position of the volume, and by setting a plurality of proportionality constants with a single volume, the input setting can be performed according to the parameter setting. Therefore, different characteristics can be obtained with a single volume, parameters can be changed with a small number of electric components, the number of changeover switches, setting volumes, and the like can be reduced, and the number of components can be reduced to reduce the cost of the device.

There are two types of characteristic patterns that can be performed in one function mode. However, by adopting the first embodiment and the second embodiment at the same time, it is also possible to implement the parameter setting with two or more types of change points in one function mode. Further, in the case where the parameters are set so that three or more types can be set in the one-function mode, the following can be performed.

Embodiment 3 1 and 2 are the same as those in the first embodiment, and a description thereof will be omitted. FIG. 6 is a flowchart for controlling the relationship between the acceleration / deceleration setting time and the volume rotation angle by a control circuit used in the third embodiment in which the parameter changing device according to the present invention is used in an inverter device. FIGS. 7A and 7B are patterns showing a relationship between an acceleration set time and a volume rotation angle used in a third embodiment in which the parameter changing device according to the present invention is used for an inverter device, wherein FIG. 7A shows a pattern A, and FIG.

However, when the present invention is implemented, any one of the acceleration time setting volume 7, the deceleration time setting volume 8, and the output frequency setting volume 9 is used. Can be set to one or more.

The flowchart shown in FIG. 6 is called when the power is turned on. In step S15, it is determined that the power is turned on. When the power is not turned on, this routine is exited.
If it is determined in step S15 that the power is turned on, the acceleration time setting volume 7 is determined in steps S16 and S17.
It is determined whether the acceleration time setting volume value Vx is the maximum value or the minimum value. This determination is made when the present embodiment is applied to the acceleration time setting volume 7, the deceleration time setting volume 8, and the output frequency setting volume 9.
It can be set by one or more of the acceleration time setting volume 7, the deceleration time setting volume 8, and the output frequency setting volume 9, or a combination thereof. Step S1

In step S21, a change in the acceleration time setting volume value Vx of the acceleration time setting volume 7 is determined, and if there is no change in the acceleration time setting volume value Vx, the parameter setting is set as the volume acceleration time setting value Xx in step S22. Is set in the memory Mx of the non-volatile memory 12 and the volume acceleration time set value Xx = Vx. When the change in the acceleration time setting volume value Vx of the acceleration time setting volume 7 is determined in step S21, the volume rotation is performed in the characteristic pattern A, characteristic pattern B, and characteristic pattern C selected in steps S18 to S20 in step S23. A parameter corresponding to the angle θ is set as a volume acceleration time set value Xx. And step S
At 24, the selected value is stored in the memory Mx of the nonvolatile memory 12, and the routine exits. The characteristic pattern A, characteristic pattern B, and characteristic pattern C selected in steps S18 to S20 have characteristics as shown in FIG.

In the characteristic pattern A, when the acceleration time setting volume value Vx is smaller than the volume threshold value VA corresponding to the volume rotation angle θA, the acceleration time setting volume value Vx is set as the volume acceleration time setting value Xx, and the parameter setting is performed by volume acceleration. Time setting value Xx = VxA.
When the acceleration time setting volume value Vx is not less than the volume threshold value VA, the acceleration time setting volume value Vx is multiplied by a proportionality constant 10 to obtain a volume acceleration time setting value Xx, and the parameter is set as the volume acceleration time setting value Xx = 10 VAx. In the characteristic pattern B, the acceleration time setting volume value Vx corresponds to the volume rotation angle θB, and the acceleration time setting volume value Vx is multiplied by a proportional constant 5 to obtain a volume acceleration time setting value Xx.

xB. In the characteristic pattern C, when the acceleration time setting volume value Vx is less than the volume threshold value VC corresponding to the volume rotation angle θC, the parameter is set as the acceleration time setting volume value Vx as the volume acceleration time setting value Xx. When the acceleration time setting volume value Vx is not less than the volume threshold value VC, the acceleration time setting volume value Vx is multiplied by a proportional constant 15 to obtain a volume acceleration time setting value Xx, and the parameter is set as the volume acceleration time setting value Xx = 15Vx.

As described above, in the present embodiment, in the parameter changing device for changing the control parameter of the control circuit 10 by the displacement of the volume comprising the acceleration time setting volume 7, the volume rotation of the volume comprising the acceleration time setting volume 7 is provided. Angles θA, θB, θC

In this embodiment, the change of the output characteristic corresponding to the displacement is determined by selecting a characteristic pattern according to the maximum position or the minimum position of the volume of the acceleration time setting volume 7 at the time of turning on the power, and changing the characteristic. Since the corresponding output characteristics are changed, the output characteristics with respect to the displacement can be changed to three characteristic patterns for the function mode depending on the position of the volume at the time when the power is turned on. Therefore, it is possible to change the characteristic pattern in which the proportional constant of the parameter is different from the arbitrary maximum position or minimum position of the volume, and to have multiple proportional constants with a single volume, and to set the input according to the parameter setting. It can be carried out. Therefore, different characteristics can be obtained with a single volume, parameters can be changed with a small number of electric components, the number of changeover switches, setting volumes, and the like can be reduced, and the number of components can be reduced to reduce the cost of the device.

As described above, in the present embodiment, in the parameter changing device for changing the control parameter of the control circuit 10 by the displacement of the volume composed of the acceleration time setting volume 7, the output characteristic corresponding to the displacement of the acceleration time setting volume 7 In contrast, the proportional constant Kx that can be displaced based on the initial position of the volume when the power is turned on is changed and input to the control circuit 10. Therefore,
The volume of the acceleration time setting volume 7 changes the volume acceleration time setting value X by the volume's original proportional constant with respect to the displacement of the volume rotation angle θ of the volume.
Since the proportionality constant Kx can be changed with respect to the output characteristic for changing x, regardless of the characteristics of the volume itself, when inputting parameters with the acceleration time setting volume 7,
An input area of a plurality of parameters can be set, and an acceleration time setting magnification switch 5 for setting a setting magnification of “× 1” of the acceleration time shown in the conventional example, and an acceleration time for setting a setting magnification of “× 10” of the acceleration time Switches such as the setting magnification switch 6 can be omitted.

Note that the initial position of the volume when the power is turned on means not only the position based on the position when the power is turned on, but also within a predetermined time range after the power is turned on. In this embodiment, the change of the output characteristic corresponding to the displacement is performed by changing the acceleration time setting volume 7 at the time of turning on the power.
Since the proportionality constant is selectively selected according to the maximum position or the minimum position, and the output characteristic corresponding to the displacement is changed, the output characteristic with respect to the displacement is changed according to the position of the volume at the time of turning on the power. Can be changed to three proportional constants.

Therefore, the proportional constant of the parameter can be changed from an arbitrary maximum or minimum position of the volume, and a single volume can have a plurality of proportional constants, and input setting can be performed according to the parameter setting. it can. Therefore, different characteristics can be obtained with a single volume, parameters can be changed with a small number of electrical components, and the number of changeover switches, setting volumes, etc. can be reduced,
By reducing the number of parts, the device can be made inexpensive, and the device can be reduced in size and enhanced in function. Further, it is possible to select one of a plurality of proportional constants having different input characteristics of the parameters depending on the initial position of the volume, thereby increasing the user's freedom of selection. In particular, the change of the output characteristic with respect to the displacement is performed by setting the maximum or minimum position of any one or more of the acceleration time setting volume 7, the deceleration time setting volume 8, and the output frequency setting volume 9 when the power is turned on. Therefore, the characteristic to be set becomes linear or substantially linear with respect to the volume rotation angle θ, and the setting is easier than the nonlinear setting.

In this type of parameter changing device,
The size of the device can be reduced by reducing the number of components such as various setting switches and volume according to the miniaturization of the electronic circuit. In the fourth embodiment, the proportionality constant is set by determining the maximum position or the minimum position of the acceleration time setting of the acceleration time setting volume 7 at the time when the power is turned on. Only one of the positions can be determined.

Embodiment 5 1 and 2 are the same as those in the first embodiment, and a description thereof will be omitted. FIG. 9 is a flow chart in which the control circuit controls the relationship between the acceleration setting time and the volume rotation angle used in the fifth embodiment in which the parameter changing device according to the present invention is used in an inverter device. In this embodiment, only the input from the acceleration time setting volume 7 will be described. However, when the present invention is implemented, any one of the acceleration time setting volume 7, the deceleration time setting volume 8, and the output frequency setting volume 9 is used. Can be set to one or more.

The flowchart shown in FIG. 9 is called when the power is turned on. First, it is determined in step S50 that the power is turned on. When the power is not turned on, the routine is exited. When it is determined in step S50 that the power is turned on, it is determined in step S51 whether the acceleration time setting volume value Vx of the acceleration time setting volume 7 is the minimum value. When this embodiment is applied to the acceleration time setting volume 7, the deceleration time setting volume 8, and the output frequency setting volume 9, the acceleration time setting volume 7,
It can be set by one or more of the deceleration time setting volume 8 and the output frequency setting volume 9 or a combination thereof. In step S51, the acceleration time setting volume 7
When it is determined that the acceleration time setting volume value Vx is the minimum value, the acceleration time setting volume 7
The change in the acceleration time setting volume value Vx is waited for, and the proportionality constant Kx selected in step S53 is multiplied by the acceleration time setting volume value Vx. That is, the volume rotation angle θ
Proportional constant K to the acceleration time setting volume value Vx corresponding to
The parameter is set using the value Kx · Vx multiplied by x as the volume acceleration time set value Xx, and the routine exits. If it is determined in step S51 that the acceleration time setting volume value Vx of the acceleration time setting volume 7 is not the minimum value, the process waits for a change in the acceleration time setting volume value Vx of the acceleration time setting volume 7 in step S54. At this time, parameters are set with the acceleration time setting volume value Vx selected in step S55 as the volume acceleration time setting value Xx, and the routine exits.
If there is no change even after waiting for a change in the acceleration time setting volume value Vx of the acceleration time setting volume 7 in step S54, the elapse of t2 seconds is determined in step S56.
If the acceleration time setting volume value Vx does not change even after the lapse of seconds, the acceleration time setting volume value Vx at that time is not changed.
Is set as the volume acceleration time set value Xx, and the routine is exited.

As described above, the parameter changing device according to the present embodiment is a parameter changing device for changing the control parameter of the control circuit 10 by the displacement of the acceleration time setting volume 7. Acceleration time setting volume value V corresponding to
A value Kx · Vx obtained by multiplying x by a proportional constant Kx is set as a volume acceleration time set value Xx, and an acceleration time set volume value Vx corresponding to the volume rotation angle θ is set as a volume acceleration time set value Xx. With respect to the output characteristic of the volume with respect to the displacement, the area in which the volume can be displaced is represented by 2
Can be changed to one. In particular, since the change of the output characteristic with respect to the displacement is to set the proportionality constant by the minimum position of the acceleration time setting of the acceleration time setting volume 7 at the time when the power is turned on, the characteristic to be set is the volume rotation angle. It becomes linear or substantially linear with respect to θ, and is easier to set than non-linear. Further, in the above embodiment, the initial setting is performed based on the minimum position of the acceleration time setting of the acceleration time setting volume 7 at the time when the power is turned on. However, in the case of implementing the present invention, the initial setting is performed based on the maximum position. Can also. In this embodiment, the change of the output characteristic corresponding to the displacement is performed by selectively selecting a proportional constant according to the maximum position and / or the minimum position of the acceleration time setting volume 7 at the time when the power is turned on. Therefore, the output characteristic with respect to the displacement can be changed to a proportional constant with respect to the function mode depending on the position of the volume at the time when the power is turned on.

Therefore, the proportional constant of the parameter can be changed from an arbitrary maximum position and / or minimum position of the volume, a plurality of proportional constants can be provided by a single volume, and an input setting corresponding to the parameter setting is performed. be able to. Therefore, different characteristics can be obtained with a single volume, parameters can be changed with a small number of electric components, the number of changeover switches, setting volumes, and the like can be reduced, and the number of components can be reduced to reduce the cost of the device. In addition, the size and function of the device can be reduced. Further, if the volume is not changed after determining whether or not the input characteristics of the parameter are different depending on the initial position of the volume, the value of the volume is adopted as the parameter setting value. This is suitable when it is not necessary to make frequent selections. In particular, in this embodiment, there is no need to use a non-volatile memory for storing parameter setting values used in the past. In the fifth embodiment, the proportional constant is changed depending on the position of the acceleration time setting volume 7, but the proportional constant is initially set within a predetermined time, and thereafter, based on the initial setting. Arbitrary parameters can be set.

The flowchart shown in FIG. 10 is called when the power is turned on. First, it is determined in step S60 that the power is turned on. If a predetermined time t3 or more has elapsed since the power was turned on, the process proceeds to step S67. If it is determined in step S60 that the power is turned on, step S6 is performed.
In step 1 and step S62, it is determined whether the acceleration time setting volume value Vx of the acceleration time setting volume 7 is the maximum value or the minimum value. When the present embodiment is applied to the acceleration time setting volume 7, the deceleration time setting volume 8, and the output frequency setting volume 9, the acceleration time setting volume 7, the deceleration time setting volume 8, and the output frequency setting volume are used. It can be set by one or more of the volumes 9 or a combination thereof. In step S61, the acceleration time setting volume value V of the acceleration time setting volume 7
When it is determined that x is the maximum value, in step S63, a proportional constant Kx of 10 (magnification Kx = 10) is selected. When it is determined in step S62 that the acceleration time setting volume value Vx of the acceleration time setting volume 7 is the minimum value, in step S65 1/10 of the proportionality constant Kx (magnification K
x = 1/10). When it is determined in steps S61 and S62 that the acceleration time setting volume value Vx of the acceleration time setting volume 7 is not the maximum value or the minimum value, in step S64, the proportional constant Kx is set to 1 (magnification Kx =
Select 1). In step S66, the elapse of t3 seconds is determined, and the fact that the processing in steps S61 to S65 has been performed within t3 seconds after the power is turned on indicates that the proportional constant Kx
To identify. In step S67, a change in the acceleration time setting volume value Vx of the acceleration time setting volume 7 is determined, and if there is no change in the acceleration time setting volume value Vx, the parameter is set as the volume acceleration time setting value Xx in the previous operation in step S68. The value used and stored in the memory Mx of the nonvolatile memory 12 is set, and the volume acceleration time set value Xx = Vx. When the change in the acceleration time setting volume value Vx of the acceleration time setting volume 7 is determined in step S67, the proportional constant selected in steps S63 to S65 is multiplied by the acceleration time setting volume value Vx in step S69. That is,
The parameter setting is performed by setting a value Kx · Vx obtained by multiplying an acceleration / deceleration time setting volume value Vx corresponding to the volume rotation angle θ by a proportional constant Kx as a volume acceleration time setting value Xx. Then, in step S70, the non-volatile memory 12
Set value of volume acceleration time Xx = Kx in the memory Mx of
Vx is stored, and the routine exits. After a lapse of t3 seconds from the power-on, the processing of steps S67 to S70 is directly performed.

As described above, the parameter changing device is a parameter changing device for changing the control parameter of the control circuit 10 by the displacement of the acceleration time setting volume of the acceleration time setting volume 7 in the acceleration time setting volume corresponding to the volume rotation angle θ. The value Kx · Vx obtained by multiplying the value Vx by the proportional constant Kx is set as the volume acceleration time set value Xx
With respect to the output characteristic of the volume with respect to the displacement, the area of the proportional constant Kx where the volume can be displaced is changed to 3 or more. In this embodiment, the change of the output characteristic corresponding to the displacement is made by selecting a proportional constant according to the maximum position and / or the minimum position of the acceleration time setting volume 7 set within a predetermined time after the power is turned on. Since the output characteristic corresponding to the displacement is selectively selected and the output characteristic corresponding to the displacement is changed, the output characteristic with respect to the displacement can be changed to a proportional constant with respect to the function mode depending on the position of the volume at the time when the power is turned on.

Therefore, the proportional constant of the parameter can be changed from an arbitrary maximum position and / or minimum position of the volume, a plurality of proportional constants can be provided by a single volume, and an input setting corresponding to the parameter setting is performed. be able to. Therefore, different characteristics can be obtained with a single volume, parameters can be changed with a small number of electric components, the number of changeover switches, setting volumes, and the like can be reduced, and the number of components can be reduced to reduce the cost of the device. In addition, the size and function of the device can be reduced. Furthermore, if the volume is not changed after determining whether the power input of the volume changes the input characteristics of the parameter depending on the initial position within a predetermined time, the value of the volume is adopted as the parameter setting value. Therefore, it is also suitable when it is not necessary to frequently select parameters. In particular, since the change of the output characteristic with respect to the displacement is to set the proportional constant by the maximum position or the minimum position of the acceleration time setting of the acceleration time setting volume 7 at the time of turning on the power, the characteristic to be set is changed. It becomes linear or substantially linear with respect to the volume rotation angle θ, and is easier to set than non-linear. Further, after elapse of t3 seconds from the power-on, by directly performing the processing of steps S67 to S70, parameter change control during operation can be performed.

In this embodiment, the change of the output characteristics corresponding to the displacement is performed by setting the acceleration time setting volume 7, the deceleration time setting volume 8, and the deceleration time setting volume 8 within a predetermined time set from the time when the power is turned on. Since the proportional constant is selectively selected depending on the maximum position and / or the minimum position of the output frequency setting volume 9 and the output characteristic corresponding to the displacement is changed, the position of the volume at the time when the power is turned on is changed according to the position of the volume. The output characteristic with respect to the displacement can be changed to a proportional constant with respect to the function mode. Accordingly, the proportional constant of the parameter can be changed from any of the maximum position and / or the minimum position of the acceleration time setting volume 7, the deceleration time setting volume 8, and the output frequency setting volume 9, and a plurality of proportional constants can be set with a single volume. And input settings can be made in accordance with the parameter settings. Therefore, different characteristics can be obtained with a single volume, parameters can be changed with a small number of electric components, the number of changeover switches, setting volumes, and the like can be reduced, and the number of components can be reduced to reduce the cost of the device. In addition, the size and function of the device can be reduced. Furthermore, if the volume is not changed after determining whether the power input of the volume changes the input characteristics of the parameter depending on the initial position within a predetermined time, the value of the volume is adopted as the parameter setting value. Therefore, it is also suitable when it is not necessary to frequently select parameters. In particular, in the present embodiment, the functions of the acceleration time setting volume 7, the deceleration time setting volume 8, and the output frequency setting volume 9 can be provided in the single setting volume 21, so that the use of the inverter device 2 is particularly effective. It is possible to reduce the size.

As described above, when the acceleration / deceleration time and the output frequency are set by the setting volume 21 in the inverter device 2 of the present embodiment, the selected function mode includes the acceleration time setting function, the deceleration time setting function, and the output frequency setting. Since the function is displayed by the blinking state of the light emitting diode 22, the setting volume 21 allows the acceleration time setting function, the deceleration time setting function, and the output frequency setting function to be selected without fail, and the parameter setting can be performed accurately. Further, the acceleration time setting volume 7, the deceleration time setting volume 8, and the output frequency setting volume 9 have only one volume, and the ratio occupied by the components becomes extremely small even in consideration of the combination with the light emitting diode 22. In the meantime, in the example of the inverter device 2, the miniaturization is extremely promoted. In particular, in the present embodiment, since a plurality of parameters can be set with one volume, the size can be further reduced. The parameters input by the setting volume 21 are easy to set because there are no discontinuities.

Further, as the acceleration time setting volume 7, the deceleration time setting volume 8, the output frequency setting volume 9 and the setting volume 21, well-known volumes can be used. Can be used as a change in the resistance value for a linear movement, usually, the change in the resistance value for a predetermined rotation angle or the change in the resistance value for a predetermined linear movement is a linear or substantially linear change, A human can easily estimate the parameter set value and input is easy.

In each of the above embodiments, step S
The determination of 50 is made when the power is turned on, but this can be made when the power of the main routine is turned on or when the power of the main routine is not turned on. Further, in each of the above-described embodiments, the function of displaying the parameter set value is not provided. However, if character-shaped display means such as liquid crystal is used for the control circuits 10 and 20, the reliability is further improved. And
In each of the above embodiments, the case where the acceleration time setting volume 7 or the acceleration time setting volume 7, the deceleration time setting volume 8 or the acceleration time setting volume 7, the deceleration time setting volume 8, the output frequency setting volume 9 or the setting volume 21 is used. However, when implementing the present invention, one or more constant changeover switches can be replaced with one or more volumes, and the invention can be applied to the use of one or more volumes.

Further, the maximum position or the minimum position of the volume in each of the above embodiments does not mean the position of the maximum resistance value or the minimum resistance value of the volume itself. It means a range that can be defined as a resistance value or a minimum resistance value. Depending on an embodiment, it is 60 to 70% or more of a maximum resistance value or 4 to 70% of a maximum resistance value.
It can be defined as 30% or less, or can be defined as 50% or more of the maximum resistance value or less than 50% of the maximum resistance value.
