Access groups MOTOR
via HMI:
Description:
You can use this parameter to define the inverter IGBT switching frequency.
The inverter switching frequency may be adjusted according to the appliction needs. Higher switching frequencies
imply less acoustic noise in the motor. However, the switching frequency choice results in a compromise among
the acoustic noise in the motor, the inverter IGBT losses and the maximum permitted currents.
The reduction of the switching frequency reduces the effects related to the motor instability, which occurs in
certain application conditions. Besides, it reduces the earth leakage current, preventing the actuation of the
faults F0074 (earth fault) or F0070 (output overcurrent or short-circuit).
ATTENTION!
Check the output current data considering the switching frequency when it is different from the
default in table B.4 available in annex B - Technical Specifications of the CFW501 user's manual.
