Our motors mostly have that are fed externally with 230V AC and a small recitifier at the brake makes DC voltage of it.
Up to now we have always been switching the the motor brake with a relay where one contact interrupted the 230V AC and one contact interrupted the DC voltage.
Is this common practice?
What if you only interrupt the 230V AC, I suppose in that case the relay would less suffer from the DC current interruption, but will the brake fall off as fast as when the DC was interrupted?
What configuration do you use to swith a motor brake? What relais do you use?
Thanks
