Note 1. The cables are based on the 600V vinyl cables. The cables (U, V, W) in the table assume that the distance between the
servo motor and servo amplifier is 30m or less.
2. Twist the cables for connection of the regenerative brake option (P,C).
3. Used with the UL/C-UL Standard-compliant models. (AMP make)

6 - 2 - 2 No-fuse breakers, fuses, magnetic contactors

Always use one no-fuse breaker and one magnetic contactor with one servo amplifier. When using a fuse
instead of the no-fuse breaker, use the one having the specifications given in this sections.

6 - 2 - 3 Power factor improving reactors

The input power factor is improved to be about 90%. For use with a single-phase power supply, it may be
slightly lower than 90%. Make selection in the auxiliary equipment selection table according to the motor
to which the reactor will be applied.
