ABB ACS880-07 - Additional Requirements for ABB High-Output and IP23 Motors; Additional Requirements for Braking Applications; Additional Requirements for Explosion-Safe (EX) Motors; Additional Requirements for Non-ABB High-Output and IP23 Motors

Additional requirements for explosion-safe (EX) motors
If you use an explosion-safe (EX) motor, obey the rules in the requirements table above.
In addition, consult the motor manufacturer for any further requirements.
Additional requirements for ABB motors of types other than M3_, HX_, AM_ and AX_
Use the selection criteria given for non-ABB motors.
Additional requirements for braking applications
When the motor brakes the machinery, the intermediate circuit DC voltage of the drive
increases, the effect being similar to the motor supply voltage increasing by up to
20 percent. Consider this voltage increase when specifying the motor insulation
requirements if the motor will be braking a large part of its operation time.
Example: Motor insulation requirement for a 400 V AC line voltage application must
be selected as if the drive were supplied with 480 V.
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.
