Yaskawa servo driver debugging software is an auxiliary tool launched for the driver of the same name. In the past, many users wanted to download the software, but they could not find its official website. Now Xiaobian can share it with everyone for free, and those who need it can download the experience.
The servo driver of Yaskawa only supports the communication protocol MECHATROLINK-II of Yaskawa control system. It can only be controlled by pulse sequence when used with other manufacturers' PLCs. In this example, Siemens 1217C PLC is used to control the servo.
On the wiring, Yaskawa drives use different control methods, and the wiring is also slightly different. Let's take location mode as an example. The hardware wiring diagram is as follows:
The wiring diagram with 1217C is as follows:
l Software configuration
Yaskawa servo driver can be debugged using SigmaWin +, and the software can be downloaded from the official website. After installation, the interface is as follows:
Click the "Menu" button and select Connect Servo in the start.
The system will automatically search for the Yaskawa servo driver connected to the computer. As shown below:
The automatic search function can search the connected servos and motors, without having to configure some related parameters of the motors. Click "Connect". You can see the connected drives from the following figure.
Click Configure to open the drive parameter configuration interface. as follows:
We can first jog the motor to see if the wiring is correct.
Next, configure the parameters of the drive. Open the parameter editing table and set the rotation direction:
Set the control mode to position control:
Set some parameters of position control, such as: command pulse shape, filter selection, etc. The filter is selected according to the type of controller.
Then you need to set the input and output signal distribution, and select the distribution mode 1;
(/ S-ON) Signal distribution selection ON (closed) is valid;
Prohibit forward and reverse drive allocation, choose to always fix the signal to forward and reverse drive.
Because this motor is an absolute encoder, the SEN terminal needs to be set to ON. By default, the 5V input is valid. There is no 5V power supply, so it is effective to modify the CN1-40 terminal ON.
After setting these parameters, the motor can be controlled from the PLC.
The last item is to change the electronic gear ratio so that the PLC program corresponds to the actual number of motor rotations. This motor encoder is a 24-bit resolution encoder. Therefore, the motor receives 16,777,216 pulses for one revolution. The Siemens technology axis is set for 1000 pulses per revolution, so the electronic gear ratio is 16777216/1000.
