Sodick A500

Hi

I have some problems with my Sodick A 500. It's starting normally but after few seconds the voltage is dropping slowly down to zero and the machine returns to the startpoint, it's the same whitout water. It looks like a short circuit, but the machine is driving normaly in G00 without M05. So it can't be. If I change HP from 4 to 20 voltage is 150V, then it is going, but there isn't power enough to cut. The power is about the same level, as when I adjust the wire.
Is there anybody who have tried the same, or know what could cause this problem?

have you looked at your discharge cables?

Yes they are OK.
