Programmable path override

This command influences path feed in the NC program if this needs to be different for feed and rapid traverse blocks. The programmed override for path motions is active if at least one axis moves. This does not affect the mode of operation of real-time influencing of feed by the PLC.

An additional function is provided for programmable axis override.

If an axis override is also defined for an axis involved in path motion, the effective path override results from multiplication of the two override values.

Notice

notice

The G166 function suppresses the programmed override values.

#OVERRIDE [ FEED_FACT<expr> RAPID_FACT<expr> ]

FEED_FACT<expr>

Override factor for feed blocks [0.1% - 200%].

RAPID_FACT<expr>

Override factor for rapid traverse blocks [0.1% - 200%].

Programing Example

prg_example

Programmable path override

%path_override

N10 G00 G90 X0 Y0 Z0

 (Path override G01 122.765%, G00 155.7%)

N20 #OVERRIDE [FEED_FACT=122.765 RAPID_FACT=155.7]

N30 G01 X100 Y100 Z100 F1000             Effective feed=1227.65

 (Path override G01, G00 100%)

N40 #OVERRIDE [FEED_FACT=100 RAPID_FACT=100]

N50 G01 X200 Y200 Z200 F1000             Effective feed=1000
