Cause Remedy
The brake resistor temperature monitoring at plug X20
has been tripped.
Possible causes:
• The external brake resistor is overheated so that the
thermal contact integrated in the brake resistor has
been switched.
• An open circuit or a loose contact at the connections
mentioned above has occurred.
• Check brake resistor temperature monitoring.
• Provide for sufficient cooling of the external brake
resistor.
• Check terminals for open circuit or loose contact.

Cause Remedy
The Ixt overload check has tripped.
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.
