Wiring Of Terminals Related To The Encoder - Mitsubishi Electric 800 Series Instruction Manual

3.3.3

Wiring of terminals related to the encoder

Use shielded twisted pair cables (0.2 mm
use several cables in parallel or use a thick cable, according to the wiring length. To protect the cables from noise, run them
away from any source of noise (e.g. the main circuit and power voltage).

The wiring length can be extended to 100 m by increasing the 5 V power supply (approximately to 5.5 V) while using six or more 0.2 mm
