Note 1. Use cable with 600 V min. withstand voltage for main circuits.
2. Consider allowable current reduction ratio if cables are bundled in PVC or
metal ducts.
3. Use temperature-resistant cable under high ambient or panel temperatures
where normal vinyl cables rapidly deteriorate.

8.3.2 Wiring Instructions

To ensure safe and stable operation, always refer to the following wiring instructions.
D For signal lines and PG feedback lines, use twisted-pair wires and multicore shielded twisted-
pair wires (Yaskawa Drawing No. B9400064 or DE8400093).
The maximum allowable wiring length is as follows: 50 m (164.04 ft) for I/O lines (at 24 V
power supply), 20 m (65.62ft) for PG feedback lines, and 50 m (164.04 ft) for MECHATRO-
LINK communication line. Cut off the excess portion of the cable to minimize the cable
length.
D For a ground wire, use as thick a cable as possible. At least grounding to less than 100 Ω is
recommended. Always ground one point only.
