the P4 group and PC group parameters to determine the output voltage.
6: When the simple PLC voltage source is a simple PLC, you need to set the PC group
parameters to determine the given output voltage.
7: PID: The output voltage is generated according to the PID closed loop. For details,
see the introduction of the PA group PID.
8: Communication reference The voltage is given by the host computer through
communication.
When the above voltage source is selected from 1 to 8, 0 to 100% corresponds to the output
voltage 0V to the motor rated voltage.
