Note
A socket compatible with the stepper motor is included in the delivery.
Possible faults due to high frequency radiation exposure (e.g. from the coil and its cable)
must be prevented for the proper response of the proximity sensors and stepper motor,
e.g. by routeing the cables separately.
Cable and connection plug must be fastened
properly so that a cable break does not
occur.
