Parameter

P-STUP-00033

Memory size for backward motion

Description

This parameter defines the memory size in bytes used for backward motion on the path. During start-up, the NC checks whether the required minimum size is available. If this is not the case, a warning is output and the memory size is set to the required minimum value. If the size is set to 0, the “forward/ backward motion on the path” function is not available. The maximum size is only limited by the resources available on the PC.

Parameter

fb_storage_size[i] where i = 0 to 11
(maximum number of channels: 12, application-specific)

Data type

UNS32

Data range

0 ... MAX(UNS32)

Dimension

----

Default value

0

Remarks

Currently covered path in the NC program (PCS)

Description

Reads the current distance covered in the NC program since program start or since the last # DISTANCE PROG START CLEAR NC command. The calculation is based on the current position in the current NC block.

Value

Explanation

HLI_SC_FEEDHOLD

0x0001

Path feed stop

HLI_SC_VFG

0x0002

No axis-specific feed enable.

HLI_SC_SINGLE_BLOCK

0x0004

Single step mode active.

HLI_SC_M00_OR_M01

0x0010

M00 (programmed stop), M01 (optional stop) is active.

HLI_SC_PLC_ACKNOWLEDGE

0x0020

Stop occurs due to waiting for an acknowledgement from the SPS. This may occur as a result of the output of M or H technology functions but is not restricted to them alone.

HLI_SC_OVERRIDE_ZERO

0x0040

Override = 0.

HLI_SC_OVERRIDE_RAPID_ZERO

0x0080

Override = 0 with rapid traverse blocks

HLI_SC_DELAY_TIME

0x0200

Dwell time.

HLI_SC_CHANNEL_SYNC

0x0800

Channel synchronisation is active.

HLI_SC_IPO_INPUT_EMPTY

0x1000

Input FIFO of the interpolation is empty.

HLI_SC_IPO_INPUT_DISABLED

0x2000

Input of function blocks (e.g. motion blocks etc.) disabled.

HLI_SC_WAIT_FOR_AXES

0x8000

Stop occurs due to waiting until a commanded axis swap is completed.

HLI_SC_CHANNEL_ERROR

0x00010000

An error occurred in the channel.

HLI_SC_WAIT_TECHNO_ACK

0x00020000

Waiting for acknowledgement of M/H/ST technology functions.

HLI_SC_W_C_AFTER_COLLISION

0x00040000

After a detected collision, waiting for motion resumption.

HLI_SC_SLOPE_SUPPLY_PROBLEM

0x00080000

Block supply problem (only occurs in conjunction with HSC slope).

HLI_SC_BACK_INTERPOLATION

0x00100000

Back interpolation after tracking mode is active.

HLI_SC_STOP_REVERSIBLE

0x00200000

Stop since M00 (programmed stop) is active. However, the NC program can be processed backwards despite M00 (available as of V3.1.3039.01).

HLI_SC_BREAKPOINT_STOP

0x00400000

Stop after a breakpoint (stop point) is reached; available as of V3.1.3039.01.

HLI_SC_M0_STOP

0x02000000

Stop after an M00 function is reached

HLI_SC_M1_STOP

0x04000000

Stop after an M01 function is reached

HLI_SC_INSERT_STOP_AT_DIST

0x08000000

Stop after an M function inserted by the Control Unit “Inserting stop marks” is reached.

HLI_SC_DEC_SYN_CHAN_EMPTY

0x10000000

Decoder is waiting for synchronisation. NC channel has no jobs.
