The blind hollow shaft of the rotary encoder is slid onto the motor’s drive shaft andfastened with a central screw. The stator is mounted via a centering diameter and fastened
appropriately—the manner of fastening can be designed by the customer. A proposed
fastening option, where the encoder flange is clamped via a fastener kit consisting of a
fixing clamp, a spring washer, and a mounting screw, is available from HEIDENHAIN uponrequest (see Mounting accessories).

Mounting aid
To avoid damage to the cable, use the mounting aid to connect and disconnect the cable
assembly. The pulling force must be applied only to the connector of the cable assembly, andnot to the wires.
