Servomotor / Servo Driver Topic: Servomotors with Countermeasures against Harmonics

FAQ No. FAQ00436

Question

Are there any Servomotors that have countermeasures against harmonics?

 

Answer

The W-series Servomotors have countermeasures against harmonics.
The W-series Servomotors are equipped with a terminal connection for a DC Reactor, so a DC Reactor can be connected.

OMRON offers Reactors to control harmonics in other Servomotors besides the W-series Servomotors. AC Reactors for Inverters can be used with the Servomotors above.

OMRON AC Reactors for Inverters are listed below, so use the corresponding AC Reactor.

Connect one Reactor per Servo Driver.
 

Servo Driver model     Reactor model
R88D-UP04V:            3G3IV-PUZBAB2.5A4.2MH
R88D-UP08V:            3G3IV-PUZBAB5A2.1MH
