Effect of the NC/PLC interface stop signals
The effect of the NC/PLC interface stop signals on manual traversing using a handwheel (abort
or interruption of the traversing motion) can be set using machine data:
MD20624 $MC_HANDWH_CHAN_STOP_COND (definition of the handwheel traversing
behavior, channel-specific)
MD32084 $MA_HANDWH_STOP_COND (behavior when manually traversing using a
handwheel)
NC/PLC interface signal
DB11 DBX0.5 (mode group
stop)
DB11 DBX0.6 (mode group
stop, axes plus spindle)
DB21, ... DBX7.3 (NC Stop)
DB21, ... DBX7.4 (NC stop,
axes plus spindle)
DB21, ... DBX6.0 (feedrate
disable)
DB21, ... DBB4 (feed rate
override)
DB31, ... DBX4.5 (rapid tra‐
verse override)
DB21, ... DBB5 (rapid tra‐
verse override)
DB31, ... DBX4.5 (rapid tra‐
verse override)
DB21, ... DBX12/16/20.3 (ge‐
ometry axis 1/2/3: Feedrate
stop)

An axis/spindle is always traversed with revolutional feedrate
MD32050 $MA_JOG_REV_VELO (revolutional feedrate for JOG)
or
MD32040 $MA_JOG_REV_VELO_RAPID
(revolutional feedrate for JOG with rapid traverse override)
depending on the master spindle.
The behavior of the axis/spindle depends on the setting data:
SD43300 $SA_ASSIGN_FEED_PER_REV_SOURCE
(revolutional feedrate for positioning axes/spindles)
The behavior of a geometry axis on which a frame with rotation acts,
depends on the channel-specific setting data:
SD42600 $SC_JOG_FEED_PER_REV_SOURCE
(control of the revolutional feedrate in JOG)
