Access Configurable
See also: F8-F11, H40
Select range according to the connected inertia in relationship to the motor
inertia.
H39 Carrier Frequency Select
Range: 2-15 [kHz]
Default: 2
Access Tunable
This parameter affects the audible sound of the motor, noise emission form
the inverter, inverter temperature, and leakage current. If the set value is

Range: 0=Volts/Frequency Control
1=Slip Compensation Control
2=PID Feedback Control
3=Sensorless Vector Control
Default: 0
