14. OPTIONS AND AUXILIARY EQUIPMENT

The cables between the servo amplifier and brake unit and between the resistor unit and brake unit should be as short as possible. The cables longer than 5m(16.404ft) should be twisted. If twisted, the cables must not be longer than 10m(32.808ft).

The cable size should be equal to or larger than the recommended size. See the brake unit instruction manual. You cannot connect one set of brake unit to two servo amplifiers or two sets of brake units to one servo amplifier.
