Does anyone know what an "Axis Head 1 Theta DAC limit error during Move Absolute Command" may mean? It occurred during production. I have checked through the board's program for errors but cannot see any.

I remember this problem but can't remember exactly what the reason was. It might have been the wrong pullup resistor on the MEI interface board used for the home photo on the y axis. You are right, after a couple hours the machine would work fine.

Thanks for your help. Solved it - The spindles on the head were stiffer than the other heads, so greasing it fixed it.

This particular Yamaha Head I/O Board is a common failure. Yamaha supply an updated version which is less likely to fail. The cause of the problem that you see is due to the connectors on the flexing and damaging the inner layers of the board. The on

Are you sure the anvil is coming up? You might try running a program w/o parts or boards (no continuity check) and watching to see if everything is moving when it should be. Do you use continuity checking? If so, what are the results?

Hi, did anybody face such error(attached)? After calibrate all axis I get this error. "E202074 : Z axis of left head : SERVO alarm. Turn off the power to the machine and perform inspection" - see attachement. Machine was fully working day
