New ATC Fault

My triac has stopped tool changing, the carousel drops down and moves to position under spindle then stops, eventually it times out.

I have cleaned all the limit switches with contact cleaner and check that their corresponding diagnostic bits flash when pressed and when toolchanging.

Bit stumped as to why tool carousel won't rotate round when it will manually, anyone got any suggestions?

It could be a broken wire.

Try rotating it when it's in i's home position.

The tool carousel rotates using the manual button, but not with the M32/M33 codes in mdi or within a program although i am not sure if they ever worked. I know that the [M34] Rotate Carousel Half Turn has never worked.

It may be worth setting diagnostic 453 bit 0 to a 1.

This will set the timers & counters.

Just to wrap this up...

There was a break in one of the carousel motor wires, all sorted now. Thanks for the pointers.
