Further information
SD42010 $SC_THREAD_RAMP_DISP
When a block containing DITS and/or DITE is inserted in the main run, the programmed run-in/
run-out path is transferred into the setting data SD42010 $SC_THREAD_RAMP_DISP:
● SD42010 $SC_THREAD_RAMP_DISP[ 0 ] = programmed value of DITS
● SD42010 $SC_THREAD_RAMP_DISP[ 1 ] = programmed value of DITE
If no run-in/run-out path is programmed before or in the first thread block, the current value of
the setting data is used.
Behavior following channel / mode group / program end reset
SD 42010 values which have been overwritten by DITS and/or DITE remain active even
following a channel / mode group / program end reset.
Behavior following warm start
In case of a warm start, the setting data is reset to the values which were active before
overwriting by DITS and/or DITE (standard behavior).
If, however, the values programmed with DITS and DITE shall also be active following a warm
restart, the setting data SD42010 $SC_THREAD_RAMP_DISP must be listed in the machine
data MD10710 $MN_PROG_SD_RESET_SAVE_TAB:
MD10710 $MN_PROG_SD_RESET_SAVE_TAB[<n>] = 42010
Behavior if the run-in and/or run-out path is very short
If the run-in and/or run-out path is very short, the acceleration of the thread axis is higher than
the configured value. This causes an acceleration overload on the axis.
Alarm 22280 "Programmed run-in path too short" is then issued for the thread run-in (with the
appropriate configuration in MD11411 $MN_ENABLE_ALARM_MASK). The alarm is purely for
information and has no effect on part program execution.
