3203h Feedback Selection Function In this object, the sources of the presets are defined for the commutation and the velocity and position control. A value change in the Operation enabled state shows no immediate effect. Value changes in objects are buffered and read out upon changing to the Operation enabled state.

The bits have the following meaning here: Bit 0: If the bit is set to "1", this sensor is used for position feedback. Bit 1: If the bit is set to "1", this sensor is used for velocity feedback. Bit 2: If the bit is set to "1", this sensor is used for commutation feedback in Closed-Loop. Subindex 01h always corresponds to the first (and always existing) sensorless feedback. Subindex 02h corresponds to internal encoder. Which sensor the controller takes into account for the individual controllers (commutation, velocity, position) is implicitly specified by the order of the sensors. The search always begins with sensor 2 and continues in ascending order until all existing sensors have been queried. If a sensor is found whose feedback is set, it is assigned to the corresponding controller and the search ended. Note: If bit 0 in 3202h is set to "0", closed loop is deactivated; bit 2 (commutation) then has no meaning. Bit 1 for the velocity and bit 0 for the position in the respective subindices are still used for the display of the actual position and speed values.
