Additional requirements for explosion-safe (EX) motors
If you will use an explosion-safe (EX) motor, follow 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 M2_, M3_, M4_, HX_ and
AM_
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 increasing the motor supply voltage 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 drives with an IGBT supply unit or regenerative rectifier
unit
It is possible to increase the intermediate circuit DC voltage from the nominal (standard)
level with a parameter in the supply unit control program. If you choose to do this, select
the motor insulation system which withstands the increased DC voltage level.
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).
