SAFETY SINE/COSINE INCREMENTAL ENCODER
Unless otherwise specified, a friction coefficient of 0.14 is assumed for all screw
connections.
Unless otherwise specified, a strength class of 8.8 is assumed for the screws.
The encoder cable must be routed free from any traction, so that no additional torque is
applied to the encoder. The minimum bending radii of the cable are to be complied with.
7.1.1 General mounting advice for encoders with solid shaft
Check the shafts for offset.
•
Protect the tolerance of the compensating element during mounting from too great
•
a degree of bending and also from damage.
Align the coupling to the shafts, and screw together without pre-loading.
•
The connection between encoder and drive shaft should be configured in such a way that
it is impossible for the connection to break.

7.1.2 General mounting advice for encoders with solid shaft
Mounting an encoder with a coupling on a shaft.
The following sequence is to be respected during assembly:
1. Slide the encoder on the shaft.
2. Screw the stator coupling/torque stop onto the flange of the drive, without
pretension.
3. Tighten the clamping ring to the recommended torque, without pretensioning the
stator coupling/torque stop.
