Detailed Description
2.6 Block search Type 5 SERUPRO
The new setting must be stored in 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'
Identification of the active SERUPRO in the interface
DB21, ... DBX318.1
The VDI signal from NCK channel (NCK→PLC)
DB21, ... DBX318.1 (block search via program test is active)
has the following meaning and effect:
The NC runs in the internal "Program test" mode until the target block of the search is
activated in the main run and the program status changes to "Stopped".
During this time, interface "Block search via program test is active" is set to 1.
2-42
; 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.
