14. OPTIONS AND AUXILIARY EQUIPMENT
14.2.2 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 section.
Servo amplifier
MR-J2-10C
MR-J2-20C
MR-J2-40C
MR-J2-60C
MR-J2-70C
MR-J2-100C
MR-J2-200C
MR-J2-350C
14.2.3 Power factor improving reactors
The power factor improving reactors improve the phase factor by increasing the form factor of servo
amplifier's input current.
It can reduce the power capacity.
The input power factor is improved to be about 90%. For use with a 1-phase power supply, it may be
slightly lower than 90%.
In addition, it reduces the higher harmonic of input side.
When using power factor improving reactors for two servo amplifiers or more, be sure to connect a power
factor improving reactor to each servo amplifier.
