Identification of the Inverter Model and Accessories
Description:
This parameter identifies the inverter model, distinguishing frame, supply voltage and rated current as per
6.2 on page 6-2.

Description:
This parameter presents the inverter power supply according to identification performed after power-up.
P297 – Switching Frequency
Adjustable
Range:
Properties:
Description:
You can use this parameter to define the inverter IGBT switching frequency.
The inverter switching frequency may be adjusted according to the application 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 F070 (output overcurrent or short-circuit).
