(3) Connection instructions
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 5 m (twist five times or more per
one meter). Even when the cable is twisted, the cable should be less than 10 m. Using cables longer
than 5 m without twisting or twisted cables longer than 10 m, may result in the brake unit malfunction.
