Note
A socket compatible with the stepper motor is included in the delivery.
Possible high frequency radiation exposure (e.g. from the coil and its cable) must be observed
with regard to the proper response from the proximity sensors and stepper motor. Cables must
be laid separately.
Cable and connection plug must be
fastened properly so that a cable break
does not occur.
