No Reaction Fault Trouble WarningLocked
Cause
Remedy
The motor temperature monitoring mode at plug X??
has triggered.
Possible causes:
• The motor is overheated so that the thermal contact
integrated into the motor has been switched.
• An open circuit or a loose contact at the connections
mentioned above has occurred.
• Check motor temperature monitoring.
• Provide for sufficient cooling of the motor.
• Check terminals for open circuit or loose contact.

Possible causes:
• Wrong dimensioning of the device with regard to its
motor load.
• Load cycles are not complied with.
• Check and, if required, correct dimensioning of the
device and the motor load with regard to technical
data.
• Reduce motor load cycles (observe load cycles accord-
ing to documentation).
