Evaluation of the thermal contact via digital input
As an alternative to the integration of the thermal contact via a mains contactor, the brake
resistor can also be monitored via a digital input. Please use a Lenze system cable. The
response to the input signal must be parameterised in the FB Editor using the »Engineer«.

Evaluation of the thermal contact via analog input
As an alternative to the integration of the thermal contact via a mains contactor, the brake
resistor can also be monitored via an analog input. Please use a Lenze system cable. The
