Initial setting for SERUPRO
Machine data:
MD20112 $MC_START_MODE_MASK
is used to define the initial setting of the control for part program start with respect to G
codes (especially the current plane and settable zero offset), tool length compensation,
transformation, and axis couplings.
There is a special chance, for the SERUPRO operation, with:
MD22621 $MC_ENABLE_START_MODE_MASK_PRT
to select a deviating basic setting at the normal start of the part program.
The new setting must be stored in the machine data:
MD22620 $MC_START_MODE_MASK_PRT
.
The meaning of the bits of MD22620 is identical to those of MD20112.
Example: The synchronous spindle coupling at the beginning of the SERUPRO operation is
retained for the part program start.
$MC_START_MODE_MASK = 'H400'
$MC_START_MODE_MASK_PRT = 'H00'
$MC_ENABLE_START_MODE_MASK_PRT = 'H01'
Basic logic functions: Mode group, channel, program operation, reset response (K1)

Detailed description
2.6 Block search Type 5 SERUPRO
; synchronous spindle coupling not
configured
; is switched off
; remains active.
; $MC_START_MODE_MASK_PRT is
evaluated in SERUPRO instead of
$MC_START_MODE_MASK.
