Motor and motor cable
Check the insulation of the motor and motor cable as follows:
1. Check that the motor cable is disconnected from the drive output terminals U2, V2 and
W2.
2. Measure the insulation resistance between each phase conductor and the Protective
Earth conductor using a measuring voltage of 500 V DC. The insulation resistance of
an ABB motor must exceed 100 Mohm (reference value at 25 °C or 77 °F). For the
insulation resistance of other motors, please consult the manufacturer’s instructions.
Note:
Moisture inside the motor casing will reduce the insulation resistance. If
moisture is suspected, dry the motor and repeat the measurement.
