Going through an instruction manual...

Going through an instruction manual...

Going through an instruction manual...

(OP)
I was reading up on calibrating electronic controls for a particular piece of equipment and came upon a phrase which instructed to "block motor" to measure voltage (Umin and Umax). The parent company is in Germany and have not ran across this verbiage before. I was wondering if anyone else has experienced this. Thank you.

RE: Going through an instruction manual...

Ja, "Motor festbremsen", which means "Brake the motor so it doesn't turn". That is what you need to do when you adjust the current loop in a DC drive, for instance.

What kind of equipment is it about? Som motors cannot take full current for more than a few seconds when braked. The collector gets deformed if it isn't allowed to turn.

Half full - Half empty? I don't mind. It's what in it that counts.

Thank you! The motors are small 220v, single phase, take-up/winder motors. Voltage for the current loop is 30v (Umin) and 180v(Umax).
