I have some troubles with a Mitsu Meldas M50 based Mori TV-30. There's a mysterious interlock on all axis and I need to dig around in the ladder to find the cause. Probably a sensor/switch problem on one of the various APC/ATC switches. No previous experience with ladder diagnostics so any help would be greatly appreciated. The MEAU site has the document I mentioned but it isn't available in my part of the world. If anyone could share a copy or point me in the right direction I'd be most grateful!

Thanks/Harri

If you have the manual number I could forward it.

Thanks Al, but I haven't got the number. I found the reference to this document in one of your answers
The control is based on Mitsubishi M50M, but the ladder is written by Mori Seiki. That's all the info I have..

Just to clarify, MEAU won't have the ladder for your machine, only the PLC programming manual.
I assume you can see the ladder on the screen and trouble shoot it?
Apart from a Ladder hard copy, it also helps if you have the I/O listing/designations.

Thanks again AL, you are right, I was looking for PLC programming manual, not my specific ladder.

I managed to find a faulty pressure switch so all is well again.
