F40 Carrier frequency (KHz) : 004-016
Set this parameter to a level from 4-16KHz as required. (Default is 10 KHz).
※
Note: In situations where there is excessive vibration noise from the motor or it is required to reduce
electrical interference from the inverter caused by use of long cable then the carrier frequency
can be adjusted as follows:-
x
To reduce interference due to long cable decrease carrier frequency.
x
To reduce motor increase carrier frequency. If so then the output current from the inverter will
be de-rated according to the following table.
