Motor selection and compatibility

1. Select the motor according to the rating tables in
the DriveSize PC tool if the default load cycles are not applicable.
2. Make sure that the motor ratings are in the allowed ranges of the drive control

4. Consult the motor manufacturer before using a motor in a drive system where
the motor nominal voltage differs from the AC power source voltage.
5. Make sure that the motor insulation system withstands the maximum peak
voltage in the motor terminals. See the
required motor insulation system and drive filtering.
Example: When the supply voltage is 440 V and a drive with a diode supply is
operating in motor mode only, the maximum peak voltage in the motor
terminals can be approximated as follows: 440 V · 1.35 · 2 = 1190 V. Check that
the motor insulation system withstands this voltage.
