Response (Lenze setting printed in bold) Setting: C00585 ( Adjustable response)
 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.
