Requirements Table - ABB ACS580-04 Hardware Manual

Optional du/dt filters protect motor insulation system and reduce bearing currents. Optional
common mode filters mainly reduce bearing currents. Insulated N-end (non-drive end)
bearings protect the motor bearings.

Requirements table


The following table shows how to select the motor insulation system and when optional
ABB du/dt filters, insulated N-end (non-drive end) motor bearings and ABB common mode
filters are required. Failure of the motor to fulfil the following requirements or improper
installation may shorten motor life or damage the motor bearings and voids the warranty.
