Servomotor / Servo Driver Topic: Use External Signal to Release Brake of Servomotor

FAQ No. FAQ00468

Question

Can I use an external signal to release the brake of a U-series AC Servomotor equipped with a brake?
 

Answer

We recommend using the brake interlock signal.

Open the connector case on the Servo side of the cable and add the brake interlock signal there.

Often, a Programmable Controller output is used as a brake signal, but because it is difficult to time the signal accurately, this method may cause falling on a vertical axis and excessive brake wear, due to the brake being applied when the motor cannot be stopped or the brake being released before the servo lock can be applied.
