6. For the communication cable, use a double-core cable(VCTF) or
twisted pair cable ( with shield). Keep the cable away from power
lines and strong electric circuits.
Note4) Control the cable wiring length of the encoder within 5m or less.
7. The total length of the communication cable must be 500m or less.
