3.9.3 Connecting a Reactor for Harmonic Suppression
The converters have reactor connection terminals for power supply harmonic suppression that can be used as
required.
Connect a reactor as shown in the following figure.
Note 1. Connection terminals for DC reactor 1 and 2 are short-circuited at shipment. Remove the lead wire for
short-circuit, and connect a DC reactor.
2. Reactors are not included. (Sold separately.)
3. To use the SERVOPACK with a DC reactor, use the terminals on the converters.
