Cause Remedy
The motor temperature monitoring function at the plug
connector X106, terminal T1 /T2, has tripped.
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.

Cause Remedy
The Ixt overload check has tripped.
• Operating threshold = 100 % Ixt (adjustable in
C00123
)
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
according to documentation).

Cause Remedy
The device indicates that the maximally possible torque
at the motor shaft has been reached.
• C00057
displays the current torque.
Reduce motor load.

Cause Remedy
Maximum current monitoring has tripped.
• The instantaneous value of the motor current has
exceeded the limit value set in C00939
.
Check and, if required, correct dimensioning of the load
with regard to the installed device power.
