Hello guys,
I have a problem with my machine. When program (spindle, axis and water pump) started or turn off, machine sometimes showing a Gross positioning error... Sometimes when spindle rotate and I hand turn on pump is the same problem. I know what mean Gross positionig error, but now it is not relate with loose in machine. It look like the voltage dropped... I change contactor from pump and nothing better. I do not know where I should looking problem.
