G920 (INIT program) - set parameters for part extraction

If an ejector is used to extract the part from the counter-spindle (variable #3017=1), the part positioned in the counter-spindle is ejected each time the machine is RESET. The ejector is activated in the INIT program following a START CYCLE and the incompleted part is therefore lost following each RESET. When setting up a highly worked part and a long cycle time, this feature can slow down optimum machining parameters. To overcome this, an additional parameter is provided

Operation:
If an ejector is used to extract the part from the counter-spindle (variable #3017=1), the part positioned in the counter-spindle is ejected each time the machine is RESET. The ejector is activated in the INIT program following a START CYCLE and the incompleted part is therefore lost following each RESET. When setting up a highly worked part and a long cycle time, this feature can slow down optimum machining parameters. To overcome this, an additional parameter is provided.

Tip:
A value of 1 entered into this parameter prevents part ejection during the INIT program (operation 4:3)
following a RESET.
Programming syntax: G920 P1=1
This tip is valid for the DECO 13a, 13b 20a and 26a machines.

WARNING:
It is essential that the part is manually removed from the counter-spindle when proceeding with a modification to the variables #3003 (part length) and #3009 (part pick-up distance). There is a risk of collision when machining in counter-operation, because the part is no longer clamped in the counter spindle at the same spot.
