Chapter 7│Options
The following peripheral device options can be installed to improve the drive performance.
Contact the local distributor to purchase the options if needed.
7.1 AC Reactor Option
7.1.1 Installing an AC Reactor
The non-linear components such as rectifiers and SCRs on the drive input side will cause high
harmonic input current which interrupts the power supply and affects the power factor. To
suppress the surges in currrent and improve the power factor, install an AC reactor on the
drive input side in the following situations.
 To suppress harmonic current or improve the power factor of the power supply
 To suppress voltge surges on the input power when using a phase advancing capacitor
switch so as to protect the connected devices.
 A large capacity power transformer (600kVA and above) is connected to the drive.
Note: Always install an AC reactor when connecting a SCR such as a DC drive to the same power supply regardless
of the power supply conditions.
7.1.2 AC Reactor Wiring Example
Note: Do not connect the AC reactor to the drive output side (secondary side).
