This property sets the source of the position feedback for the motion. The position feedback comes from either the motor (usually), or the load. The load feedback is commonly used when working in the dual loop mode. Dual loop is set during the SERCOS phase run-up.
When the feedback is set to external, the POSITIONFEEDBACK property is used to get feedback and calculate position following error. The POSITIONFEEDBACK units are defined by POSITIONFACTOR and not by POSITIONEXTERNALFACTOR.
