  In a machine that performs unwinding or winding of a long material such as paper, film, thread, and wire, and intermediate tension control, which is an object of the present invention, the control axis is often not a single axis but a plurality of axes. In the conventional power amplifier device for clutch / brake control, when setting a plurality of units, it is necessary to perform the setting for each unit. Therefore, it is troublesome when setting a plurality of power amplifier units. Also needed. In addition, each power amplifier device could not be centrally managed, set and monitored.

  Further, the conventional apparatus only has a display function of the main body and a connection function that can connect an extremely limited display setting panel to the outside. For this reason, the user cannot freely change the operation display design of the operation screen of the external setting display panel, and the display screen configuration cannot be freely configured.

  Furthermore, in the conventional apparatus, when the current setting is changed by changing the material applied to the machine, it is necessary to change the current setting itself from the outside each time. For this reason, another setting storage and switching device is required outside. Furthermore, in the case of current setting by an analog input command, there is a problem that a rapid setting change cannot be realized due to the influence of the analog input filter.

  In view of the above, the present invention enables simultaneous setting and monitoring of a plurality of power amplifier devices using a programmable display freely designed by the user, and allows a new user to create screen data. In addition, an object of the present invention is to provide a clutch / brake power amplifier device and a control system thereof that can easily perform complicated settings using only an operation panel built in the main body.

  According to the power amplifier device for clutch / brake of the present invention, it is possible to simultaneously set and monitor a plurality of power amplifier devices using a programmable display freely designed by the user, and at the same time, screen data necessary for the setting. If a maker provides, a new user can easily perform complicated settings using only an operation panel built in the main body without creating screen data.

Embodiment 1 FIG.
Embodiment 1 of the present invention will be described below with reference to the drawings.

First, a single power amplifier device according to the first embodiment will be described.
1A and 1B are external views of the clutch / brake power amplifier device 100 according to the first embodiment. FIG. 1A is a front view, FIG. 1B is a side view, FIG. 1C is a top view, and FIG. FIG.
The segment display unit 11 is a means for displaying the state of the apparatus and calculation results, and setting items and setting values for various settings. The key switch 12 is a setting means for switching the display displayed on the 7-segment display unit 11 and changing the set value. The external connection terminal 13 is a terminal for connecting wires such as constant current output for clutch / brake control, various analog commands, various contact input commands, and power input.

The programmable display connector 14 is a connector for connecting a programmable display communication cable of a programmable controller.
A signal for performing RS-422 communication with the programmable display of the programmable controller and a signal for detecting that the programmable display is connected to the connector 14 are input / output. In addition, since a 5V power supply for connecting a small programmable display is also connected, when a 5V power supply type small programmable display is connected, power can be supplied to the programmable display simply by connecting this connector. . Further, when connecting a medium-sized programmable display, only the communication line is connected to the display, and power supply to the programmable display can be performed from a separate power source. The programmable display that can be connected to this connector requires that the communication signal conforms to RS-422.

  The parallel digital signal input connector 15 is an input terminal for issuing an output current command from an external digital ON / OFF signal. The input switching command from the connector 15 is also an input command function for switching a plurality of output current setting values set in advance in the internal memory of the apparatus or an inertia compensation gain set in advance in the internal memory by function switching setting. Can be changed.

  The RS-485 communication terminal 16 is a data communication cable connection terminal between the plurality of power amplifier devices 100. The signal specification of the device connected to this terminal needs to be determined by RS-485. Further, the communication procedure of this terminal conforms to the mutual communication procedure of the programmable controller, and communication between the programmable controller and the power amplifier device is also possible. If a communication program that matches this communication procedure is executed on a personal computer or the like, communication with the personal computer or the like is possible.

  The RS-485 communication termination resistor changeover switch 18 is a switch for turning on / off a termination resistor for absorbing reflection of the RS-485 communication signal, and turns on the termination resistor only for devices located at both ends of the communication line.

  The communication signal confirmation lamp 17 is a lamp for blinking each time the H / L level of the communication signal input to the RS-485 communication terminal block 7 is switched to confirm that the communication signal is operating. is there. This lamp can confirm each signal for transmitting signal confirmation and receiving signal confirmation.

  The memory cassette 19 is a removable external memory that can store various settings of the power amplifier device. Settings can be copied alternately between the internal setting memory and the memory cassette 19, and settings can be backed up to a memory cassette in case of failure or copying settings to another power amplifier device. Can be used to increase. In addition, since the priority of the storage destination of various settings can be set in the internal memory and the external cassette, it can be used for temporary setting change and setting restoration.

Next, the internal configuration of the clutch / brake power amplifier apparatus 100 according to the first embodiment will be described.
In FIG. 2, the microcomputer 20 executes a program for performing arithmetic control and memory management communication processing of the power amplifier device 100.
The internal non-volatile memory 22 is a memory that can retain the memory even when the power is turned off, and stores various setting data, operation switching settings, and the like of the power amplifier device 100. Further, a hardware specific value for correcting a variation in hardware characteristics inherent in the circuit of the power amplifier device 100 is also stored. This hardware specific value is obtained by measuring a characteristic in a shipping test or the like and storing the value.

The data stored in the internal nonvolatile memory 22 is read to the internal volatile memory 21 when the power is turned on, and is stored and held again when the setting is changed or when the power is turned off. Similarly, the memory in the memory cassette 19 is a non-volatile memory. The microcomputer 20 can write or recall data by switching data to each memory.
The analog-digital converter 23 converts an analog command input to the power amplifier device into a digital value, and the digital-analog converter 24 converts the command value calculated by the microcomputer 20 as an analog output.

The constant current amplifier 25 is an output amplifier for clutch / brake control, and controls and amplifies the current flowing through the exciting coil of the clutch / brake in accordance with an analog command from the microcomputer 20.
The constant current amplifier 25 is composed of a current detection means, a means for comparing and controlling the detected current and the output command, and an amplifier for amplifying the result. Each means is processed inside the microcomputer 20; Whether to process with hardware is case by case. Therefore, not only the internal configuration of the constant current amplifier 25 and the configuration of the constant current control but also the amplification type and whether the PWM control or the series control is performed are not essential in the present invention. Further, constant voltage control may be performed instead of constant current control.

Further, the data processing block in the power amplifier apparatus 100 will be described with reference to FIG.
The RS-422 communication function 26 is a function for transmitting and receiving an RS-422 serial communication signal at a predetermined timing. Generally, the RS-422 communication function 26 may be realized by hardware built in the microcomputer 20. .
The RS-422 communication procedure 27 is a function for controlling the RS-422 communication function 26 and performing serial transmission / reception procedure control. In the case of the power amplifier apparatus 100, the serial transmission / reception procedure with the programmable display connected to the programmable display connector 14 of FIG. 2 is controlled as RS-422 communication.

  This RS-422 communication procedure 27 uses the same communication procedure as the program connection communication of the programmable controller. Further, the programmable display connection confirmation means 29 allows the power amplifier apparatus 100 to confirm whether the programmable display is connected in hardware.

  Generally, the communication procedure for programmer connection of the programmable controller differs for each manufacturer of the programmable controller, but if it matches one of the major manufacturers, the communication procedure with the programmable display can be matched. It is. This is because the programmable display side has communication procedure switching means that can cope with the communication specifications for programmer connection of the major programmable controller manufacturers of each company.

  The programmable controller communication simulation function 28 is a function for performing mutual conversion between the programmable display and the internal memory of the power amplifier device 100. The programmable display unit confirms connection of the programmable controller at the time of communication initialization with the programmable controller. For example, the programmable controller displays the model code of the programmable controller and the power outage retention range of various communication elements (each data and ON / OFF signal). I don't start.

In addition, the programmable display device designates various communication elements by placing an element number, a predetermined memory address, and a code number in the communication procedure 27. Therefore, in the power amplifier device 100, this addressing is performed with the address of the programmable controller. It is necessary to convert the communication data into the memory address of the power amplifier device 100. Moreover, the transmission data from the power amplifier device 100 must be transmitted to the programmable display device in the same form as the data transmitted from the programmable controller for the monitor and setting information of the memory of the power amplifier device 100.
By realizing the RS-422 communication procedure 27 and the programmable controller communication simulation function 28 in combination, the power amplifier device 100 behaves as if it is a programmable controller when viewed from the programmable display, and mutual communication is performed. Can be established.

  The RS-485 communication function 30 is a function for transmitting or receiving an RS-422 serial communication signal at a predetermined timing. As with the RS-422 communication function 26, an RS-485 serial communication signal is determined. The function of transmitting or receiving at a given timing is different from that of the RS-422 communication function 26 in the signal specification in either one-to-one communication or many-to-many communication. On the other hand, the RS-485 communication procedure 31 has various communication procedures, unlike the RS-422 communication for programmer connection. Therefore, the microcomputer switches the communication procedure executed in the RS-485 communication procedure 31 for use. In the case of the power amplifier device 100, two types of mutual communication procedures possessed by the programmable controller can be switched.

The volatile memory 21 is a memory whose stored contents disappear when the power is turned off, and performs temporary storage. After confirming that the data changed by the key input is in an appropriate range as an input value, the data is temporarily stored in the volatile memory 21, and the power amplifier apparatus 100 performs an operation calculation based on the setting data. The setting data is held in the non-volatile memory 22 by a power failure at the timing when some setting changes are made. The setting data from the programmable display is also temporarily stored in the volatile memory 21, and after determining the setting type and range, it is stored in the address of the normal setting data. Also, display data such as results of internal calculations and input calculation values are stored in the volatile memory 21 and displayed by key operation. Similarly, if there is a request from the programmable display, it is temporarily stored as communication data and then transmitted to the programmable display.
The reason why the communication transmission / reception data is temporarily stored in the volatile memory 21 is that transmission or reception is performed via a data time series when the communication method is serial communication. Further, communication between the power amplifier devices is also stored in the temporary storage memory by the same exchange as that of the programmable display.

FIG. 4 is a list of setting monitor items of the power amplifier device 100. Here, serial numbers 1 to 16 are monitor data items, and 17 to 144 are set data items. Serial numbers 201 to 208 are ON / OFF monitor data items, and 209 to 216 are ON / OFF setting items.
The device number in this table is a data number corresponding to the data element of the programmable controller when exchanging with the program display. For example, when the D0 data is monitored with a programmable display, the output% of the power amplifier device 100 can be monitored, and when data is written to D16 from the programmable display, the data is set to the internal torque (tension) setting 0 of the power amplifier device 100. The

  If a display screen is designed and designed with a programmable display based on this table, the user can freely create a setting display screen. It is also possible for the power amplifier device manufacturer to prepare design data for a programmable display for setting monitoring in advance, and for the user to install and use it on the programmable display. Furthermore, it is possible for the user to add and change the design data of the programmable display prepared by the power amplifier device manufacturer using a personal computer.

Embodiment 2. FIG.
Next, a coil winding machine control system using a plurality of power amplifier devices 100 according to the present invention will be described as a second embodiment.
First, the mechanism of the coil winding machine will be described with reference to FIG. In FIG. 5, a coil winding machine 200 is a device that winds an electric wire 5 wound around a raw material bobbin 3 around a coil bobbin 8 by a winding motor 7. Since the tension of the electric wire 5 at this time influences the accuracy and quality of the coil wound up, it is necessary to control the tension of the electric wire 5. A portion that controls the tension of the electric wire 5 is the tension unit 1. The tension unit 1 is provided with an electromagnetic brake 2 to which a pulley is attached. A power amplifier device 100 is connected to the electromagnetic brake 2, and the power amplifier device 100 makes the excitation current of the electromagnetic brake 2 constant or variable. Thus, the tension of the electric wire 5 is controlled.

  In general, the electromagnetic brake 2 used in the coil winding machine 200 is often a hysteresis brake. This is because in such a coil winding machine, the acceleration / deceleration of the machine is fast, and the inertia of the rotating part affects the tension of the electric wire. is there. Therefore, a powder type brake may be used when the machine is slow in acceleration / deceleration with little influence of the moment of inertia of the brake or when the electric wire 5 is thick.

The guide 6 is used for traversing the electric wire 5 by moving it left and right so that the electric wire 5 can be aligned and wound around the coil bobbin 8. Further, when the electric wire 5 is entangled with the pin of the coil bobbin 8, the tangling operation is also performed by the guide 6. As a process for winding the coil bobbin 8, a repetitive operation is performed in the order of pin linking → acceleration → winding and traverse → deceleration → pin linking → wire cutting → coil bobbin replacement.
Since the tension of the electric wire 5 is different in each process, the exciting current of the power amplifier device 100 is changed for each process to change the braking force of the electromagnetic brake 2.

  Furthermore, many of the coil winding machines 200 can wind a plurality of coils on one machine. In such a case, the tension unit 1 is required corresponding to each coil bobbin 8. A plurality of power amplifier devices 100 for exciting the electromagnetic brake 2 of the tension unit 1 are also required. As described above, in the coil winding machine 200, it is necessary to simultaneously operate a plurality of power amplifier devices 100 and vary the current excited in the electromagnetic brake 2 at the same time.

Next, the coil winding machine control system in the case where the conventional power amplifier device is used and the case where the power amplifier device of the present invention is used will be described in comparison with FIG. 6 and FIG.
In the conventional example of FIG. 6, one power amplifier device 4 is connected to the electromagnetic brake 2, and the braking force of the electromagnetic brake 2 in each step of the coil winding machine from the current command switching device 9 to the power amplifier device 4. The excitation current is switched correspondingly.
The current command switching device 9 stores the excitation current of the electromagnetic brake 2 in each process as a value set in each process, and when a switching command is received from a higher-level device, the current value corresponding to the winding machine process at that timing Is commanded to the power amplifier device 4. Further, the current command switching device 9 may store the settings according to the type of coil used in the winding machine in advance and can switch the type.
In the conventional example of FIG. 6, the current command switching device 9 is constituted by a small programmable controller and a small programmable display. However, depending on the manufacturer of the winding machine, a dedicated current command switching device 9 may be used.

  On the other hand, in the coil winding machine control system using the power amplifier apparatus 100 according to the present invention of FIG. 7, the power amplifier apparatus 100 has built-in current settings and inertia compensation settings corresponding to several types, and The setting can be changed for each power amplifier device individually or collectively by the small programmable display 10 so that the current command switching device 9 in FIG. A switching command can be realized. Further, when the mutual communication between the power amplifier devices 100 and the communication specifications of the host programmable controller are matched, switching can be performed only by mutual communication without connection by I / O. If the setting switching by the type of coil exceeds the setting number of the power amplifier device 100, the memory function of the small programmable display 10 can be obtained by using a recipe function built in as a function of the small programmable display 10. Expansion is possible within the limited range.

  FIG. 8 is a diagram illustrating a mutual communication procedure between a plurality of power amplifier devices 100 connected to each other in the coil winding machine control system as shown in FIG. All communication elements between the power amplifier devices are numerical data and element numbers are assigned by station numbers. In this case, each station is responsible for four data elements. All communication exchanges between the stations are controlled by the master station as a master.

The data delivery of each station will be described by explaining the overall communication flow.
(A) The master station transmits parameters and designates the range of data to be changed. In the case of the power amplifier apparatus 100, a four-element data change request is set. Upon receiving this, the slave station prepares data to be transmitted. (B) Next, the master station transmits its own data to each slave station. In the case of the power amplifier device 100, it corresponds to four data from D000 to 003. (C) Next, the master station issues a transmission request to the slave station 1. (D) Receiving this, the slave station 1 transmits its own data.
In the case of the power amplifier device 100, data from D100 to 013 is received, and the master station and other slave stations receive this data and store it as slave station 1 data. By repeating this procedure periodically from slave station 1 to slave station 2 to... Slave station 7 to slave station 1, the communication data of each station can be shared by all stations.

In the power amplifier device 100, the role and priority are assigned to the station number so that data from the programmable display and designated data from the master station can be exchanged with the slave station. Thus, in the power amplifier apparatus 100, the master station data is set to D000 = designate station number, D001 = parameter number, D002 = parameter content, and D003 = contact command. Further, the slave station 1 is set as a programmable display connection dedicated station number, and D010 = station number designation, D011 = parameter number, D012 = parameter contents, and D013 = contact command.
Further, for the slave stations 2 and later, D0 * 0 = output% monitor, D0 * 1 = parameter number, D0 * 2 = parameter contents, and D0 * 3 = contact monitor (* is the slave station number). The station number designation of the master station and the slave station 1 designates the station number to be written or read, and the parameter number is set to the serial number of the setting list in FIG. Data corresponding to this parameter number is used as the parameter content.

  For example, when it is desired to set data in the slave station, the slave station number, setting item, and setting data whose settings are to be changed are transmitted as data of the master station or slave station 1. Then, the corresponding sub-station receiving this changes the setting data. When data is to be set in all slave stations, “0” zero is set in D000 = station number designation or D010 = station number designation. All the slave stations that have received this change the setting corresponding to the parameter number to the data corresponding to the parameter contents. To read data from the slave station, set D001 = parameter number or D011 = parameter number plus 1000. In response to this, the slave station writes the current set value in D0 * 1 = parameter number and D0 * 2 = parameter contents.

Next, a method for determining the own station number of the power amplifier apparatus 100 will be described.
In the mutual communication of the power amplifier devices, the master station occupies station number 0 and the programmable display data is occupied by station number 1 and assigned. Among these, station number 0, which is the master station, is always required in the communication line in order to control mutual communication between the power amplifier devices.
Therefore, in the power amplifier device 100 of the present invention, in addition to the station number setting as a setting parameter, any one of the power amplifier devices connected to the communication line automatically behaves as the master station.

  FIG. 9 is a flowchart showing how the power amplifier apparatus 100 determines its own station number. FIG. 10 is a diagram showing an example of station number assignment of the power amplifier apparatus 100. By determining the own station number in this way, the master station for intercommunication can be determined.

  Furthermore, the power amplifier device 100 has an operation mode called “initial setting mode” in which setting items that are indispensable when assembled to the mechanical device can be preferentially set. This setting mode is an operation mode in which the power amplifier device 100 behaves from the time of shipment until the initial setting items are completely set. The specification of the mechanical device such as the model name, rated current, and various input / output selections of the connected clutch and brake. If it is determined, the operation can be performed only for the basic setting items that must be set to the same power amplifier device.

  Further, when this “initial setting mode” is switched and canceled, it becomes a normal operation mode in which other setting items including the setting items that can be set in the “initial setting mode” can be set. In order to switch between the “initial setting mode” and another “normal operation mode”, a separate switch may be provided. However, in the case of the power amplifier device 100, the model of the clutch / brake to be connected is set. Then, the next power is turned off and turned on. If it is desired to perform the initial setting mode again, the setting memory may be initialized to the factory setting.

  The power amplifier device 100 is in the “initial setting mode” in the state after unpacking, but at this time, it is desired to make the same initial settings for all the other power amplifier devices installed in the machine. Therefore, when communication between power amplifier devices has been established after installation of the machine, the same setting is transferred to all power amplifier devices with which mutual communication has been established by setting operation of one power amplifier device. .

  The operation of one power amplifier device is determined to be that the programmable display is connected to the power amplifier device or the display setting means built in the power amplifier device is in operation or 10 seconds after the operation, and the power amplifier device that meets this condition Is automatically assigned to the master station number 0. This is the condition of S901 or S903 in FIG. If the programmable display is not connected, the process branches to S902. If the panel is operated or within 10 seconds after the operation, the process branches to S903 again. Since the own station number cannot be set in the initial setting mode, the setting of the station number 2 set as the initial value is not changed.

Therefore, in the case of the power amplifier device as the master station, the process branches to S905 in the initial setting mode. Next, in the case of the initial setting mode, the process branches to S907 to set the own station number to 0. On the other hand, in a power amplifier device to which a programmable display is not connected or a power amplifier device that is not operated, it behaves as a set initial value station number. After the “initial setting mode” is canceled, the station number designation for each unit may be changed. At this time, mutual communication can be established by setting any one of the power amplifier device mutual communication lines as a master station.
As a result, station number allocation as shown in FIG. 10 can be performed.
FIG. 11 shows an example of initial setting items for the power amplifier apparatus 100 of the present invention.

  Further, the communication method and communication procedure of this mutual communication conforms to the communication means between the programmable controllers, and it is possible to connect the programmable controller to the communication line between the power amplifier devices. For example, if a programmable controller is set as a master station, setting and monitoring can be performed from the programmable controller to the power amplifier device connected to the communication line.

When control is performed with the power amplifier device connection example for the coil winding machine as shown in FIG. 6, as described above, pin binding → acceleration → winding and traverse → deceleration → pin binding → wire cutting → coil bobbin replacement Therefore, it is necessary to change the exciting current of the brake frequently. In the conventional power amplifier device, all settings are operated by a built-in volume or switch, an external parallel signal, or an analog signal.
In addition, since the torque of the brake and clutch cannot be changed unless a command is received from outside the power amplifier device, the current command switching device 9 is always required. It was necessary to switch the output.

  However, in the power amplifier device 100, the setting is stored in the memory, and as long as the setting stored in advance is switched, it is not necessary to install the current command switching device 9 outside the power amplifier device as shown in FIG. The power amplifier apparatus 100 can use a parallel ON / OFF command, switching from a programmable display, or switching by mutual communication as a switching command. Further, in the winding machine 200 as shown in FIG. 5, it is desirable that the excitation current can be changed as quickly as possible as described above.

  In contrast to this, in the conventional power amplifier device, since all the excitation currents are set from the outside, it is necessary to temporarily take the setting into the power amplifier device. However, in the power amplifier device 100 of the present invention, the setting is necessary. Is stored in the memory, and there is no need to take in the data as long as the setting stored in advance is switched. Especially when changing the current command by changing the analog command, a filter or the like may be inserted in the analog input to cut noise and other high frequencies to increase the reliability of the command. I want to change the excitation current of the brake steeply, but I can't expect a steep response.

  In the case of the power amplifier device 100 of the present invention, each setting is calculated internally like a control block as shown in FIG. This is to correct the changing elements and variations on the machine side. Here, in the block diagram of FIG. 12, the internal (memory) torque setting 32 is written in one block. However, as described in the internal torque setting switching 34, 16 settings are switched by a setting switching command. I want you to pay attention to what you can do. This is because the machine side repeats several steps as described above.

On the other hand, during acceleration / deceleration of the machine, fluctuations in tension appear due to the inertia of the machine mechanism. In order to suppress the tension fluctuation of acceleration / deceleration due to the inertia, a command having a phase opposite to that of the tension fluctuation may be given to the clutch or brake whose tension is controlled as shown in FIG. This control output and reverse phase command works as a gain that is a fixed multiple of the output immediately before acceleration / deceleration.
For this purpose, the power amplifier apparatus 100 has an inertia compensation gain function. In the case of the power amplifier device 100, when the inertia compensation gain setting 33 is input to this function, it can be selected from an analog command and a setting stored in the internal memory. However, when the setting by the internal memory is used, it is the same as the torque setting described above. 16 settings can be stored and set in advance, and these switching operations can be performed in the same manner as the torque setting.
