Asr servotron
Wondering if anyone has a manual or any documentation pertaining to the asr servotron tfm servo amplifier as fitted to the 3c (tnc155 control) x axis motor appears to not be energising while z and y do. Z and Y do suffer from creep once energised.

Re: Asr servotron
Hi,
I've looked through all the documentation that I have, but there is very little on the 3C machines.
The wiring diagrams have already been posted. The only other relevant file is the Heidenhain TNC 151 / 155 operating manual.

Re: Asr servotron
Cheers Andy, I did think it was a long shot.
I have contacted ABB uk (who own baldor and asr) and they directed me to sms automation. Still waiting for a reply to several emails.
I have done a bit of testing with the board and found the transistors on the x channel have failed so I'm just waiting for replacements to arrive. I'm just hoping the transistors were at fault and not just the outcome of another.
I already have the tnc 155 operators /programming manual and the service manual. Was there ever a machine manual?
