The function behaves as follows:
• MD36052 $MA_STOP_ON_CLAMPING = 'H03'
• MD36052 $MA_STOP_ON_CLAMPING = 'H04'
Basic logic functions: Axis monitoring, protection zones (A3)

No longer has an effect.
The travel command is set in Look Ahead mode only for blocks with active continuous-
path mode. M82 generates a stop and thus interrupts the continuouspath mode. The Look
Ahead stopping on N410 would not be necessary because stopping occurs anyway.
Generates a stop irrespective of M83, which is executed as a function of "feedrate
override 0%". The axis is thus stopped before the first machining block.
Note
MD36052 $MA_STOP_ON_CLAMPING = 'H01' or 'H04'
Both functions can be used irrespective of the clamping of axes:
• MD36052 $MA_STOP_ON_CLAMPING = 'H01'
Generates a Look Ahead stop for the path motion if no servo enable signal is active
for the relevant axis.
• MD36052 $MA_STOP_ON_CLAMPING = 'H04'
Generates a Look Ahead stop for the path motion if the feed rate overrate = 0% at the
transition from the part-program blocks with rapid traverse to part-program blocks
without rapid traverse.
Both functions ensure that the path motion in continuous-path mode is already stopped
before the start of the relevant part-program block and not just within the part-program
block.
