Before firmware version 7.10 there is a problem when "Sensor Zero search" is used and the "Torque" value is reached during running towards the sensor.

 

If the motor is stopped at a certain position at the torque level indicated by Torque for a longer time, suddenly the motor is jumping back and then going towards the sensor again. This only stops if the sensor is reached.

 

The problem has been solved in version 7.10.
