Problem- SPINDLE STARTS ROTATING WHEN CHANGE TO MANUAL AND WHEN CLAMP OR UNCLAMP

TURNING MACHINE YANG ML25
Control FANUC 0T

I was playing up with M18, M19 in MDI to stop spindle in exact position to facilitate to load unload part from spindle.

Now when I change mode selector to manual, spindle starts rotating. It looks like machine is trying to change gear. I reset to stop it but if i clamp or unclamp chuck it starts rotating again.

How I can remove this annoyance?

I want to stop the spindle in exact position. Is there any way to do that. MTB manual says M19. but it keeps spindle rotating albeit a very slow motion.

Thanks for any help

As far as I know this ML-25A can't stop spindle in the exact position and it did not have the M19 funtion either, some other ML-25A has the M19 but soon you change the mode selector switch M19 will reset it self

Sorry for my mistake. Machine is ml60-A not 25
MTB manual says about M18 Nd M19 capabilities.
