Programmable axis override

This command allows for the axis feed, if required the different influencing of feed and rapid feed blocks in the NC program. The axis-specific programmed override is active during path motions if the axis is moving. This does not affect the mode of operation of real-time influencing of feed by the PLC.

In addition a programmable path override function is also provided.

When several axes are moved in the same NC block with different axis-specific override values, the smallest override always takes effect. If an additional path override is also defined, the effective override results from multiplying the two override values.

Notice

The G166 function suppresses the programmed override values.

<axis_name> [ OVERRIDE FEED_FACT<expr> RAPID_FACT<expr> { \ } ]

<axis_name>

Name of the axis

OVERRIDE

Identifier for axis-specific override programming. Must always be programmed as first keyword.

FEED_FACT<expr>

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

RAPID_FACT<expr>

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

\

Separator ("backslash") for clear programming of the command over multiple lines.
