Then, motor constant amendment is illustrated using Fig. 3 and Fig. 4.Fig. 3 is the flow chart of motor constant correcting process.
Fig. 4 is to represent to make the figure of the situation of the rotating speed of accumulative motor after motor initial rotation by lifting operation.
The rotating speed detected by encoder 17 implements the judgement of motor constant amendment.First, it is confirmed whether to carry
Lift operations indicate (101), and in the case where there is lifting operation instruction, encoder 17 (rotation detection portion) preserves motor speed
Lifting/it is horizontal walk inverter control unit 12 in (102).Detect number of times be more than 1 time when (103), lifting/it is horizontal walk inverter control
The value of this is detected and is preserved motor speed and the motor speed preserved are added up and preserved (104) by portion 12 processed,
Detect+1 (105) on number of times.Detect number of times be 0 when (103), lifting/it is horizontal walk circuit control device 12 directly this is detected
And the motor speed saved is preserved ,+1 (105) on detection number of times.
In addition, detecting motor speed at predetermined intervals by encoder 17 after starting lifting operation.Encoder 17
Detection motor the middle rotating speed rotated and is exported to inverter control unit in predetermined time interval.In addition, as being used for
The equipment for detecting motor rotation, is not limited to encoder or can detect the sensor of motor rotation.
Lifting/horizontal walks inverter control unit 12 when detecting that number of times is more than n times (106), if motor so far turns
The aggregate value of speed is then judged as that goods is difficult to the state risen, motor constant amendment is set less than amendment higher limit χ (107)
To open (108).Lifting/it is horizontal walk inverter control unit 12 detect number of times be not above n times when (106), returning to judgement has
Flow (101) without lifting operation.Exceed n times even in detection number of times, χ (107), is carried when motor speed so far is the above
Rise/it is horizontal walk inverter control unit 12 also resets detection number of times, from the beginning (101) of flow reprocessing.Refer to if do not operated
Show and then reset detection number of times (109).
Here, motor constant amendment is set into unlatching to refer to correct in advance to carry out inverter control to motor
The motor constant of decision.In addition, motor constant includes a resistance value and load current value etc..By by motor constant
Amendment is set to open, and corrects these values, improve from inverter be output to motor in current value.It is output to by raising electronic
Current value in machine, even for example can also make in the case where the cold local low motor of motor temperature is difficult to rotate
Motor speed rises to rated speed.
In addition, when motor constant amendment has been switched on, the processing of the control flow shown in Fig. 3 is not performed.In addition,
Once it is more than n times, to judge whether, less than after amendment higher limit χ, to reset detection number of times, on the other hand can also to detect number of times
Do not handled and end processing from the beginning (101) of flow.
Here, the n times of detection number of times for example by time, the i.e. Fig. 3 flow processing untill number of times+1 is detected from 101
The time of a circulation is set to 10mS untill 106, will be set to 100mS to the time that motor constant amendment is set to open
In the case of, N turns into 10 naturally.In addition, amendment higher limit χ is certainly different according to the model of used motor.
For example, in the case of the example shown in Fig. 4, from lifting operation is carried out to the time point that have passed through 100mS, A
More than amendment higher limit χ, so motor constant amendment will not be opened.On the other hand, B, C, D from carry out lifting operation process
100mS time point, less than amendment higher limit χ, so motor constant is modified to unlatching.
More than, according to the present embodiment, when the rotating speed of the motor during the scheduled time does not turn into value set in advance
During the above, motor constant amendment is carried out, so for example being difficult to rotate even in the cold low motor of local motor temperature
State in the case of, can also rotate motor, and lift suspended thing.
[embodiment 2]
Then, illustrate that coping with the reason for motor is difficult to rotation is not as motor temperature using Fig. 4 and Fig. 5
It is low, but the hoist engine under some abnormal conditions.In addition, omitting the description the part of repetition.Use Fig. 3~Fig. 5 explanation amendment solutions
The specific detection method removed.
Inverter control unit judges motor according to the motor speed added up and pre-determined abnormal higher limit
Whether become to be difficult to rotate due to exception.When the rotating speed for the motor for adding up is below abnormal higher limit, inverter control
Portion processed is judged as more than the rotation of motor, releases the exception of motor constant amendment and output motor.
Fig. 5 is the flow chart of motor rotation abnormality detection processing.It is electric for some reason in the processing of embodiment 1
Motivation can not rotate, and for example motor will rotate, but in the case that brake is not opened, motor constant amendment has
It is likely to become unlatching.Now, although motor can not rotate, the electric current for flowing through motor is also possible to become big.Therefore, at this
In embodiment, as upper judgement, inverter control unit 12 is walked in lifting/horizontal, with the rotating speed that is detected by encoder 17 Lai
Implement motor rotation unusual determination.
First, lifting/horizontal walks inverter control unit 12 and is confirmed whether to have lifting and step-down operation (201), when there is lifting
And during step-down operation, preserve the motor speed (202) exported from encoder., will when detecting that number of times is more than 1 (203)
The value of the motor speed this time preserved and the motor speed preserved is carried out accumulative and preserved (204), will detect number of times+1
(205).Lifting/it is horizontal walk inverter control unit 12 detect number of times be 0 when (203), directly by this preservation motor speed
Preserved, by detection number of times+1 (205).
Lifting/horizontal walks inverter control unit 12 when detecting that number of times is the M above (206), if so far electronic
The aggregate-value of machine rotating speed is then judged as that motor rotation is abnormal, by motor less than pre-determined abnormal higher limit y (207)
It is abnormal to judge to be set to open (208), motor constant amendment is set to turn off (209).Lifting/it is horizontal walk inverter control unit 12 exist
Detection number of times when being not above M time (206) even and if for more than M times, motor speed so far also for more than y when
(207), reprocessed from the beginning (201) of flow.Lifted if no operation instruction/it is horizontal walk inverter control unit 12 reset
Detect number of times (210).
Here, detection M time of number of times for example by time, the i.e. Fig. 3 flow processing untill detection number of times+1 from 201 to
The time of a circulation is set to 100mS untill 206, will set motor speed unusual determination and is set to as the time untill opening
During 1000mS, M is 10.
For example, in the case of example shown in Fig. 4,1000mS time point, A, B, C are have passed through after lifting operation is carried out
More than abnormal higher limit y, so motor rotation unusual determination is to be not turned on.On the other hand, D carry out lifting operation after by
1000mS time point, less than amendment higher limit y, so motor rotation unusual determination is opens.
In addition, abnormal higher limit y is certainly different according to the model of used motor.In addition, until judging electronic
Machine rotating speed whether the time untill exception be preferably later than than judge motor constant amendment whether be set to open untill time.
Thus, lifting/it is horizontal walk inverter control unit 12 motor speed the predetermined time turn into amendment the upper limit
In the case of being worth exception, motor amendment is set to after unlatching, if further motor speed is not raised to abnormal higher limit
More than, then it is judged as that motor rotation is abnormal and can give such as display part (not shown) by abnormal export of motor rotation.This
When, lifting/it is horizontal walk rotation of the inverter control unit 12 for example by stopping motor can preventing the damage and braking of motor
The failure of device.
In addition, judging whether the time untill exception sets motor constant amendment with judging whether until motor speed
Time untill for unlatching is identical, or can also shift to an earlier date.Thus so motor can be judged in safer side
The exception of rotation.
More than,, can be without motor when motor becomes to be difficult to rotate due to some exceptions according to the present embodiment
Constant correction and notify that motor rotation is abnormal, so motor and brake etc. can be protected.
[embodiment 3]
Then, in the present embodiment, illustrate situations below using Fig. 6, i.e., after motor constant amendment is set into unlatching,
Motor temperature is very warm, it is not necessary to the situation of the amendment of motor constant.Fig. 6 is the flow that load hour factor calculates processing
Figure.
If by the use time of hoist engine, motor heating, it is not necessary to motor constant amendment.Therefore, according to
Lifting/horizontal walks the load hour factor that calculates of inverter control unit 12 to implement motor constant amendment shut-off.In elevator function
Present treatment is performed during the state enough acted.
Here, action possible state refers to according to the lifting from input unit (not shown) or step-down operation instruction, volume

Detect whether number of times is more than 60 (304).Lifting/it is horizontal walk inverter control unit 12 detection number of times less than 60 in the case of, return
Return 301 flow.On the other hand, lifting/it is horizontal walk inverter control unit 12 detection number of times be more than 60 in the case of (302),
Reset detection number of times (303), calculated load time rate (306).
Here, load hour factor is acted according to such as hoist engine time, i.e. motor be powered after time with
Detection number of times is obtained for the ratio between 60 minutes total times of detection at 60 time point.In addition, detection is not limited total time
Due to 60 minutes, but according to the behaviour in service of user such as being suitably determined as 15 minutes, 30 minutes.In addition, preserving
The timing for the time that motor is powered is not limited to per minute, and can be every 10 seconds, walk inversion according to lifting/horizontal within every 30 seconds etc.
The disposal ability of device control unit 12 and arbitrary decision.
Lifting/it is horizontal walk inverter control unit 12 judge motor constant amendment open in the case of (307), calculate
Whether load hour factor has exceeded pre-determined amendment off value χ 1 (308).Lifting/it is horizontal walk inverter control unit 12 calculate
When the load hour factor gone out has exceeded amendment off value χ 1, motor constant amendment is set to turn off (309).Lifting/it is horizontal walk it is inverse
Become device control unit 12 when the load hour factor calculated is amendment below deviant χ, temporarily terminate load hour factor calculating
Flow
Lifting/it is horizontal walk inverter control unit 12 judge motor constant amendment turn off in the case of (307) or will
Motor constant amendment is set in the case of shut-off (309), and whether the load hour factor calculated has exceeded pre-determined bear
Lotus time rate boundary value χ 2 (310).Lifting/horizontal walk inverter control unit 12 judge to have exceeded in the load hour factor calculated it is pre-
During the load hour factor boundary value χ 2 first determined, the set load hour factor of hoist engine is exceeded, output load time rate exceeds
(311).It is pre-determined load hour factor boundary value in the load hour factor calculated that inverter control unit 12 is walked in lifting/horizontal
When χ is below 2, temporarily terminate the flow of load hour factor calculating.
Here, motor constant amendment is set to turn off and refers to be modified by opening motor constant amendment
