4.3.5.1
Analog sensors and analog Hall sensors
Where possible, shield analog sensor cables and lay them apart from (shielded) motor
cables.
Connect the shield on one end, ideally on the motor side.
4.3.5.2
Incremental encoders / Digital Hall sensors / Digital sensors
4.3.5.3
Encoders with absolute interface
Connect the shield of the encoder lines on both ends.
On the controller side near the encoder plug connector, a terminal resistance of 120
Ω
is
highly recommended between Data+ and Data–. This can be activated with DIP switch S2.
4.3.6
Using filters
The filters are divided into various function and current ranges.
Filter types:
Input-side filters: filters on the power supply side
Motor-side filters: filters that are connected between controller and motor in the motor
phases

The signal quality can be improved with a capacitor (470 nF, dielectric strength > 100 V)
between device shield and sensor supply (+5 V).
Due to the increased signal hysteresis, digital Hall sensors are more robust than analog
Hall sensors.
Incremental encoders are robust due to a four-edge evaluation in the controller.
In the case of an absolute encoder interface, signal interference immediately results in
invalid position values during the interference. A more interference-immune, differen-
tial data transmission is therefore advantageous.
