257 C-AXIS OR LS MALFUNCTION

[machinist360]

I have a Slant Turn 30 ATC with a Mazatrol T3 and I am getting an alarm that I can find no information on.

257 C-AXIS OR SHIFT LS MALFUNCTION

when I try to switch to the C Axis. When I switch it on it rotates the chuck, slows and stops then gives the alarm. I can see on the headstock that the proximity switch is activated so apparently it is indexing to the correct position. Any help would be appreciated!

Thank you.
