6: Simple PLC
If the voltage source is simple PLC mode, parameters in group F12 must be set to determine
the setting output voltage.
7: PID control
The output voltage is generated based on PID closed loop. For details, see the description of
PID in group F10.
8: Rs485 communication
The output voltage is set by the host computer by means ofcommunication.
The voltage source for V/F separation is set in the same way as the frequency source. When
the above voltage source is selected from 1 to 8, 0 to 100% corresponds to the output power
0V to the rated voltage of the motor.

Chapter 6 Description of Function Codes
The rise time of V/F separation refers to the time required for the output voltage to change
from 0V to the rated voltage of the motor. As shown in Figure 6-8:
