Trigger mark mode for residual time calculation (P-CHAN-00833)

P-CHAN-00833

Trigger mark mode for residual time calculation in the look-ahead function.

Description

This parameter defines the mode for the end of the residual time calculation in time look-ahead. The residual time is calculated up to the trigger mark based on the motion blocks available and is provided in the path interpolator status.

NC program example (transition from G0 to G1/G2/G3) Mode 0:

N10 G00 G90 X100

N20 Y200

N30 G01 Z0 F300

NC program example (M50 is end label) Mode 1:

N10 G00 G90 X100

N20 Y200

N30 M50

Parameter

eta.mode

Data type

UNS32

Data range

0: The end label of the residual time calculation is the programmed change from rapid traverse block to feed block (from G0 to G01, G02, G03) (default)

1: The end label of the residual time calculation is a programmed M/H function with the M/H number defined in P-CHAN-00832.

Dimension

---

Default value

0

Remarks

This function is available as of CNC Build V3.1.3080.16 or V3.1.3107.51.

Caution:

The required buffer effect when calculating the residual time is cancelled out by specific control blocks in the program sequence, e.g. position request or selecting/deselecting kinematic transformations (#TRAFO ON/OFF). In these cases, the residual time is 0.
