Using a motor with a lower rating or dispensing with a motor altogether
With the factory settings, m otor output phas e loss detection is active (
[Output Phase Loss]
(OPL) =
[Yes]
(YES), page 256). To avoid having to us e a m otor with the sam e rating as the drive when testing the
drive or during a m aintenance phase, deactivate the m otor output phas e loss detection
(
[Output Phase Loss]
(OPL) =
[No]
(nO)). This can prove particularly us eful if very large drives are being
tes ted with a sm all m otor.

NOTICE
MOTOR OVERHEATING
Install external thermal monitoring equipment under the following conditions:
If a motor with a nominal current of less than 20% of the nominal current of the drive is connected.
If you use the function Motor Switching.
Failure to follow these instructions can result in equipment damage.
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
If output phase monitoring is disabled, phase loss and, by implication, accidental disconnection of cables,
are not detected.
Verify that the setting of this parameter does not result in unsafe conditions.
Failure to follow these instructions will result in death or serious injury.
