We have just acquired a LC20-M, a great machine, and have brought back to life the live tooling through the use of modern programming software.

The machine and program are working great except for a random (sometimes not so random) alarm we get when the machine tries to engage the C-axis for the live tooling. The spindle will rotate slowly, stop, and then there is a clicking sound as if the C-axis is trying to lock up or engage. The machine pauses for a few seconds and you hear a second click. The “C-AXIS ENGAGING” light on the control remains flashing (should be solid when engaged correctly) and the machine alarms out with the following:

ALARM-A160 C AXIS CONNECT COMMAND

Any ideas on how to correct the problem is appreciated.

What code do you use to engage it(the C axis)? Robert

What code do you use to engage it(the C axis)? Robert

M110 ENGAGE
M109 DISENGAGE

The reason I ask is that think the alarm is a programming error, or possibly a parameters error. Sometime I get that alarm if I haven't turned off the spindle BEFORE the tool change. (Home the turret, turn off the spindle M5, then do the tool change) Hope that helps, Robert

Thanks Robert, I will look into it and let you know.
