11.11 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.
If using only one power factor improving reactor, enough improvement effect of phase factor cannot be
obtained unless all servo amplifiers are operated.

11.12 Relays (Recommended)
The following relays should be used with the interfaces:
Interface Selection example
Relay used for digital input command signals (interface DI-1) To prevent defective contacts , use a relay for small signal
(twin contacts).
(Ex.) Omron : type G2A , MY
Relay used for digital output signals (interface DO-1) Small relay with 12VDC or 24VDC of 40mA or less
(Ex.) Omron : type MY
