du/dt lters

Du/dt ltering suppresses inverter output voltage spikes and

rapid voltage changes that stress motor insulation.

Additionally, du/dt ltering reduces capacitive leakage

currents and high frequency emission of the motor cable

as well as high frequency losses and bearing currents in the

motor.

The need for du/dt ltering depends on the motor age and

insulation. For information on the construction of the motor

insulation, consult the motor manufacturer. If the motor does

not full the requirements of the lter selection table, the

lifetime of the motor might decrease. Insulated N-end (non-

driven end) bearings and/or common mode lters are also

required for motor bearing currents with motors bigger than

100 kW. For more information please see the ACS850 hardware

manual.

* 3 lters included, dimensions apply for one lter.

Mains chokes

Mains chokes are typically used to reduce harmonics in the

mains current.

Frames C to G are equipped with built-in choke as standard.

For frames A and B, the ACS850 drive modules do not

necessarily need a separate mains choke for operation. If

however separate mains choke are needed they are available

to meet different system design needs.
