Current derating
Other than stated in the technical motor data, the ARS 2320, ARS 2340, ARS 2320W and
ARS 2360W servo drives have current derating in nominal operating conditions.
The following formula can be used to calculate the output current of the output stage as a function of
the output stage frequency (f
PWM
) for values > 5 kHz or > 7,5 kHz:
I(f
PWM
) =
