KRC1 under voltage pm1 error

did you calibrate the axis?

In case of KRC1, there is a lot of stuff inside PM600, everything but KPC (600VDC supply,27VDC supply, servo drives for six axes...)

undervoltage could be an indication of a wiring problem, hardware fault (such as defective PM600), possibly missing phase or something causing too much of a current draw, even on 27VDC circuit.

Hello najafabadi,

I am also trying to fix a pm6-600, I was curious about what you meant with feedback circuit and CT. And how do you go about fixing it. CT is current transformer?

Thanks in advance
