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

70 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). The table below shows the requirements for random-
wound and form-wound non-ABB motors with nominal power smaller than 350 kW. For
bigger motors, consult the motor manufacturer.

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