Additional Requirements For Abb High-Output And Ip23 Motors; Additional Requirements For Non-Abb High-Output And Ip23 Motors - ABB ACS580 Series Hardware Manual

Additional requirements for 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).
This table shows the requirements for protecting the motor insulation and bearings
in drive systems for ABB random-wound motor series (for example, M3AA, M3AP
and M3BP).

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.
