Detailed instruction of parameters
0: No operation
1: Automatic energy-saving operation
Motor on the light load conditions,
automatically adjusts the output voltage to
save energy
Select the output setting channel at V/F curve
separation.
0: Keypad setting voltage: the output voltage
is determined by P04.28.
1: AI1 setting voltage
2: AI2 setting voltage
3: AI3 setting voltage
4: HDI setting voltage
5: Multi-step speed setting voltage;
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
inverter accelerates from the output minimum
voltage to the output maximum voltage.
Voltage decreasing time is the time when the
inverter 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)
