du/dt filters
du/dt filtering suppresses inverter output voltage spikes
and rapid voltage changes that stress motor insulation. If
the motor does not fulfil the requirements the filter
selection table, the lifetime the motor might decrease.2

. For frames and the ACS850 drive
modules not necessarily need separate mains
choke for operation.
The need for du/dt filtering depends the motor age
and insulation.8
