11. OPTIONS AND AUXILIARY EQUIPMENT
(3) Precautions for wiring
The cables between the servo amplifier and the brake unit, and between the resistor unit and the brake unit
should be as short as possible. Always twist the cable longer than 5m (twist five times or more per one
meter). Even when the cable is twisted, the cable should be less than 10m. Using cables longer than 5m
without twisting or twisted cables longer than 10m, may result in the brake unit malfunction.
