5.8 Monitoring
Many monitoring functions that are integrated into the controller can detect errors and thus protect
the device/motor from damage or overload.
• Detailed information on the individual monitoring functions can be found in the following sub-
chapters.
Parameterisable responses
If a monitoring function trips, the response set via the corresponding parameter is carried out. The
following responses can be selected:
• "No response": Response/monitoring is deactivated.
• "Fault": Change of the operating status by a pulse inhibit of the power output stage.
• "Warning": Operating status of the controller remains unchanged. Only a message is entered
into the logbook of the controller.

5.8.1 Device overload monitoring (Ixt)
In C064/1...3 displays the device utilisation (ixt) in [%] in different time intervals:
• If the device utilisation reaches the switch-off threshold set in C123 :
• The error response set in C604 will be carried out (Lenze setting: "Warning").
• The " OC5: Ixt overload " error message will be entered into the logbook.
• A setting of C604 = "0: No Reaction" deactivates the monitoring.
