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«.
