Hello,
We have a kuka KRC1 that has the error under voltage PM1. Can this error be from software settings?
Hello,
We have a kuka KRC1 that has the error under voltage PM1. Can this error be from software settings?
Any advice to fix this 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.
The problem finally solved. First we checked the IGBT which was working properly. And then we checked the feedback circuit and CT, which was the problem, and by repairing it, the problem was solved.
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
