C16 V / f base output voltage setting
When C17=60HZ, and C18=100%
For 200-240VAC, patterns based an output voltage are shown below. (For corresponding settings
at 400-480 VAC input: multiply by 2)
VAC
When the output voltage is set higher than the input voltage, the max output voltage is limited
to the max input voltage.
C23
Torque boost gain : (V / f) (%) 00.0
– 30.0%
C24 Slip compensation gain : (V / f) (%) 00.0
– 100%
C24 value= (Motor synchronization speed
– Rated speed) / Motor synchronization speed
Where:
Rated speed = The RPM Marked on the motor nameplate
Motor synchronization speed (RPM)=
120
× Motor rated frequency (50Hz or 60Hz)
Motor Poles
Example: 4 Poles,60Hz induction motor synchronization speed =
120
× 60 =1800 RPM
4
Motor synchronization speed 1725 RPM, F49 =(1800
– 1725) / 1800 = 4.2%
C25 Motor no load current : (A)
Motor no load current varies with inverter capacity F00. Adjust according the actual conditions.
C26 Electronic thermistor protection for motor (OL1)
000: Protection Enabled
001: Protection Disabled
