Mode group stop

Edge evaluation: no

Signal state 1 or

An NC stop is activated for all the channels of the mode group. The channel status of all the active

channels changes to the channel status "interrupted". All of the channels in channel status "reset"

remain in the channel status "reset". Programs that are running at this point are immediately

interrupted (at the earliest possible point, even within a block) and the program status changes to

"stopped". All the moving axes of the mode group are decelerated according to their acceleration

characteristics without contour violation. The program can be restarted with NC start. None of the

spindles of that mode group are affected.

Signal state 0 or

Channel status and program execution are not affected.

Special cases,

All the axes of a mode group that are not triggered by a program or a program block (e.g. axes

errors, ... ...

traverse because traverse keys are being pressed on the machine control panel) decelerate to rest

with mode group stop.
