CPB Modbus RTU Technical Manual

Overtemperature protection

Above a temperature of approx. 80 °C on the power board the power part of the controller switches off and the error bit is set (see objects 1001h and 1003h). After cooling down and confirming the error (see table for the controlword, "Fault reset"), the controller again functions normally.

Temperature-dependent power reduction for the CPB6

The following diagram shows the permissible continuous current as a function of the ambient temperature:

Note: Aside from the motor, the exact temperature behavior is also dependent on the flange connection and the heat transfer there as well as on the convection in the application. For this reason, we recommend always performing an endurance test in the actual environment for applications in which current level and ambient temperature pose a problem.
