General Encoder Wiring Guidelines - ABB FEN-21 User Manual

General encoder wiring guidelines

The encoders should be connected to the encoder interface module with a shielded
instrumentation cable, preferably with twisted pairs. See the encoder manual for
additional requirements. To prevent the encoder inputs from being disturbed, the
cable shield must be connected to the chassis. The connection is made automatically
through the metal hood of the plug, if the cables are connected through the cable
clamp of the plug.
1 Metal hood
2 Cable clamp
3 Cable shield
4 Cable bushing
Note: Do not route the encoder cables parallel to power (e.g. motor) cables.
Tightening torque is 0.3 Nm (2.7 lbf·in.) for the plugs.
The allocation of cable pairs is described for each connector in the following sections.
