Digital inputs for position latching (X34)
Encoder wiring
The encoders should be connected to the FEN-01 with a shielded
instrumentation cable, preferably with twisted pairs. See also 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.
Cable shield connected to the cable clamp
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.
