OT parameter, spindle stops when switching,

[Ztiggi]

i have an topper tnc150ts with fanuc OT,

my problem is that the spindle stops when running auto-mode and push feed hold, and then swith to any other mode makes the spindle stop, and i cannot start it againg without resetting the program,
this makes it impossible to stop to check inserts, or jumping in the program.

does anybody know with parameter this could be?
i cannot find it in the maintenance manual.

The way the spindle reacts is written into the ladder, It must have been how the MTB decided to do it.

You might check the keep relays. I know on the Doosan's there's a keep relay that controls whether the spindle stops when feed hold is pushed.

a keep realay? wich I can disable?

anyhow the spindle does not stop when pushing feed hold,
it stops when switching into manual mode,
and if i start it in manual, it stops when switching from manual to auto mode.

that makes it impossible to stop for changing inserts and resume machining.

and by the way, I'm a newb to cnc-forums, so i dont know what MTB means, looks to me like the manufacturer?
