3. LOAD SIDE ENCODER
(3) Internal wiring diagram
For production of the load side encoder cable, use a cable durable against the long period of flexing action.
Even though the cable length is max. 30m for the RS-422 communication, the length may be shortened
due to the power supply voltage drop or the specifications of linear encoder.
A connection example is shown below. For details, contact with the encoder manufacturer.

Note 1. For the load side encoder without Z-phase, set parameter No.PC27 to " 1
".
2. Securely connect a shield cable to the plate (ground plate) in the connector.
3. The following table shows the cable size to be used and the number of paired connections of LG and P5 when the consumption
current of the load side encoder is 350mA. When the consumption current of the load side encoder is 350mA or less, the paired
connections can be decreased.
