Hallo Matjaz,
the question is, what type of motor was originally connected and what type of sensor did that motor have? If a B&R motor was connected, then you could connect a 500 Ohm resistor to the sensor input on the Acopos. However, this could damage the motor because the motor temperature is no longer monitored. The motor would then only be protected by the temperature model calculated by the Acopos.
