4.3 Terminal Connections

(Note 1) : Please refer to the SJ300 Instruction Manual for information about wiring the logic terminals.

(Note 2) : Use a shielded, twisted pair cable for the signal cables, and cut the shielded covering as shown in the diagram below. Make sure that the length of the signal cable is no more than 20 meters. If the length exceeds 20 meters, use a VX application control device RCD-E (remote control device) or CVD-E (signal isolation) to avoid malfunction caused by EMC noise or voltage drop. Also, the signal wire for the encoder should be shielded twisted pair line of 28 AWG (0.75mm2) or more, and the distance should also be less than 20m. If more than 20m, use a 5V line driver relay amplifier.
