* manufactured before 1.1.1998
** For motors manufactured before 1.1.1998, check for additional instructions with the motor
manufacturer.
***If the intermediate DC circuit voltage of the drive will be increased from the nominal level by resistor
braking or by the IGBT supply unit control program (parameter selectable function), check with the
motor manufacturer if additional output filters are needed in the applied drive operation range.
Note 1: The abbreviations used in the table are defined below.
Abbreviation Definition
U nominal voltage of the supply network
N
U peak line-to-line voltage at motor terminals which the motor insulation must withstand
LL
P motor nominal power
N
du/dt du/dt filter at the output of the drive +E205
CMF common mode filter +E208
N N-end bearing: insulated motor non-driven end bearing
n.a. Motors of this power range are not available as standard units. Consult the motor manufacturer.
Note 2: Explosion-safe (EX) motors
The motor manufacturer should be consulted regarding the construction of the motor
insulation and additional requirements for explosion-safe (EX) motors.
Note 3: High-output motors and IP 23 motors
For motors with higher rated output than what is stated for the particular frame size
in EN 50347 (2001) and for IP 23 motors, the requirements of ABB random-wound
motor series M3AA, M3AP, M3BP are given below. For other motor types, see the
"Requirements Table" above. Apply the requirements of range 100 kW < P
350 kW to motors with P

Note 4: HXR and AMA motors
All AMA machines (manufactured in Helsinki) for drive systems have form-wound
windings. All HXR machines manufactured in Helsinki starting 1.1.1998 have form-
wound windings.
Note 5: ABB motors of types other than M2_, M3_, HX_ and AM_
Use the selection criteria given for non-ABB motors.
