Die sinking status signals

Escape channel is activated
Description	Escape channel was activated by #TRACK CHAN ON [ESCAPE] and can be started by a trigger signal. The trigger signal for escape start can be provided by backward motion at negative external velocity or by commanding a flushing process.
Signal flow	CNC → PLC
ST path	gpCh[channel_idx]^.bahn_state.escape_enabled_r
Data type	BOOL
Value range	[TRUE : ESCAPE active, FALSE]
Access	PLC is reading

Trigger consideration suspended for escape motions
Description	Consideration of the trigger for escape motions can be temporarily deactivated by the down channel. This status signal indicates whether an escape motion can be started. Suspend trigger consideration with NC command: #CHANNEL INTERFACE OFF[ESCAPE WAIT] Activate trigger consideration with NC command: #CHANNEL INTERFACE ON[ESCAPE]
Signal flow	CNC → PLC
ST path	gpCh[channel_idx]^.bahn_state.escape_trigger_is_suspended_r
REALDatentyp	BOOL
Value range	[TRUE = Trigger consideration suspended FALSE]
Access	PLC is reading

Length of the escape path
Description	This data item indicates the actual length of the escape path. The length of the geometry for “Erosion on the path” is not included. The dynamically generated path has an individual length dependent on the starting point of the escape, the escape strategy (FLAT, ALPHA, etc.) and the escape end. The length can be read by this data item. The length is independent of the distance traversed in the escape channel. This value is updated cyclically from the point when the orbit channel is activated (i.e. when the “Erosion on the path” phase is implicitly terminated).
Signal flow	CNC → PLC
ST path	gpCh[channel_idx]^.bahn_state.escape_path_length_r
Data type	LREAL
Value range	[0 <= length]
Access	PLC is reading

Current escape strategy
Description	This data item shows the currently selected escape strategy.
Signal flow	CNC → PLC
ST path	gpCh[channel_idx]^.bahn_state.escape_strategy_r
Data type	UINT
Value range	Possible values are: 0- EDM_ESC_GEOM_NONE 1- EDM_ESC_GEOM_FLAT 2- EDM_ESC_GEOM_ALPHA 3- EDM_ESC_GEOM_POINT 4- EDM_ESC_GEOM_BISECTOR
Access	PLC is reading

Change request for escape strategy active
Description	This data item shows that a change request was identified for the escape strategy, If it is impossible to change the strategy, the data item remains TRUE until the escape strategy is changed.
Signal flow	CNC → PLC
ST path	gpCh[channel_idx]^.bahn_state.escape_strategy_wait_change_r
Data type	BOOL
Value range	[TRUE / FALSE]
Access	PLC is reading

Flushing motion is active
Description	The escape channel executes a flushing motion of the PLC. When the floating point is reached, the signal reverts to FALSE.
Signal flow	CNC → PLC
ST path	gpCh[channel_idx]^.bahn_state.jump_acitve_r
Data type	BOOL
Value range	[TRUE : Flushing motion active, FALSE]
Access	PLC is reading

Erosion on the path is active
Description	This data item only indicates in the escape channel whether the escape channel is in the "Erosion on the path" phase or has entered this phase as a result of the escape. In the latter case, the signal is set to TRUE.
Signal flow	CNC → PLC
ST path	gpCh[channel_idx]^.bahn_state.approach_active_r
Data type	BOOL
Value range	[TRUE : “Erosion on the path” phase active, FALSE]
Access	PLC is reading

Orbit channel active
Description	The element indicates whether the geometry in the orbit channel is fully decoded. If the value is set to TRUE, the down channel can increase the radius from 0.
Signal flow	CNC → PLC
ST path	gpCh[channel_idx]^.bahn_state.orbit_active_r
Data type	BOOL
Value range	[TRUE : Orbit channel active, FALSE]
Access	PLC is reading

Radius in the orbit channel is 0
Description	This element indicates whether the commanded radius in the orbit channel is 0. If the value is 0, the interface to the down channel can be deactivated, for example.
Signal flow	CNC → PLC
ST path	gpCh[channel_idx]^.bahn_state.orbit_radius_zero_r
Data type	BOOL
Value range	[TRUE : Radius in the orbit channel is 0, FALSE]
Access	PLC is reading

Wait for equidistant calculation in the block
Description	The element indicates that the equidistant calculation has not yet finished in the current motion block.
Signal flow	CNC → PLC
ST path	gpCh[channel_idx]^.bahn_state.orbit_wait_extend_ncbl_r
Data type	BOOL
Value range	[TRUE : Wait state, equidistant for this motion block not yet calculated. FALSE]
Access	PLC is reading
