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 during path motions is active if the assigned axis is moving. Therefrom the real time influencing of the feed by the PLC is not affected.

As a second function also a programmable path override is available.

For several moved axes in the same NC block with different axis specific override values always the smallest override takes effect. If additionally, also a path override is defined, the effective override results from the multiplication of the both override values.

Programmable axis override 1:

The function G166 suppresses the effect of programmed override values.

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

<Axis_name > Name of the axis.

OVERRIDE Identification for the axis specific override programming.Must always be the first programmed keyword.

FEED_FACT<expr> Override factor for feed blocks [0,1% - 200%].

RAPID_FACT<expr> Override factor for rapid feed blocks [0,1% - 200%].
