Detailed instruction of parameters
6: PID setting voltage;
7: MODBUS communication setting voltage;
8–10: Reversed
Note: 100% corresponds to the rated voltage of the
motor.
The function code is the voltage digital set value when
the voltage setting channel is selected as "keypad
selection".
Setting range: 0.0%–100.0%
Voltage increasing time is the time when the VFD
accelerates from the output minimum voltage to the
output maximum voltage.
Voltage decreasing time is the time when the VFD
decelerates from the output maximum voltage to the
output minimum voltage.
Setting range: 0.0–3600.0s
Set the upper and low limit of the output voltage.
Setting range of P04.31: P04.32–100.0%
(the rated voltage of the motor)
Setting range of P04.32: 0.0%– P04.31
(the rated voltage of the motor)
