Response Of Active Synchronized Actions To End Of Program And Change In Operating Mode; Block Search - Siemens SINUMERIK 840Di sl Function Manual

Detailed description
2.7 Control system response for synchronized actions in specific operational states
2.7.6 Response of active synchronized actions to end of program and change in
operating mode
See Chapter 2.7.4 "Change of operation mode" and Chapter 2.7.5 "Program end".
Synchronized action/
technology cycle
Axis/positioning spindle
Speed-controlled spindle
Master value coupling
Measuring operations

Block search

General
Synchronized actions in the program, which have been interpreted during the block search,
are collected but their conditions are not evaluated. No actions are executed. Processing of
synchronized actions does not commence until NC Start.
IDS
Synchronized actions that are programmed with keyword IDS and are already active remain
operative during the block search.
Polynomial coefficient
Polynomial coefficients programmed with FCTDEF are collected with calculation during a
block search, i.e. they are written to system variables.
114
Modal and non-modal actions are aborted
M30 is delayed until the axis/spindle is stationary.
End of program:
MD35040 $MA_SPIND_ACTIVE_AFTER_RESET==
TRUE:
Spindle remains active
MD35040
$MA_SPIND_ACTIVE_AFTER_RESET==FALSE:
Spindle stops.
Spindle remains active when the operation mode is
changed
MD20110 $MC_RESET_MODE_MASK, Bit13 == 1:
Master value coupling remains active
MD20110 $MC_RESET_MODE_MASK, Bit13 == 0:
Master value coupling is separated
Measuring operations started from synchronized
actions are aborted
Static actions (IDS) remain active
Motion continues
Spindle remains active
A coupling started from a static
synchronized action remains active
Measuring operations started from
static synchronized actions remain
active
