Additional Requirements For Non-Abb High-Output And Ip23 Motors - ABB ACS880-07 Hardware Manual

82 Guidelines for planning the electrical installation

Additional requirements for non-ABB high-output and IP23 motors

The rated output power of high-output motors is higher than what is stated for the
particular frame size in EN 50347 (2001).
If you plan to use a non-ABB high-output motor or an IP23 motor, consider these additional
requirements for protecting the motor insulation and bearings in drive systems:
•
If motor power is below 350 kW: Equip the drive and/or motor with the filters and/or
bearings according to the table below.
•
If motor power is above 350 kW: Consult the motor manufacturer.

*** If the intermediate DC circuit voltage of the drive is increased from the nominal level due to long term
resistor braking cycles, check with the motor manufacturer if additional output filters are needed in the
applied drive operation range.
