CAUTION!
Keep the electronics free of (metal) particles!
The integrated sensOstep™ encoder uses a magnet at the end of the motor axis in order
to monitor position. The magnet naturally attracts especially tiny metal particles. These
particles might be held on the top side of the PCB and even worse – start moving in
accordance with the rotating magnetic field as soon as the motor starts moving. This
might lead to shorts of electronic contacts / wires on the board and totally erratic
behavior of the module! Use compressed air for cleaning the module if necessary.
