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 (0.75mm
2) or more, and the distance should also
be less than 20m. If more than 20m, use a 5V line driver relay amplifier.
