20.4 Programming

Changing the default setting

For a deviating machine configuration (e.g. definition of a third geometry axis), the default

setting can be adjusted via the following machine data:

MD60948 $MN_CC_ACTIVE_IN_CHAN_HSCL[1]

$MN_CC_ACTIVE_IN_CHAN_HSCL[1]='H3'

$MN_CC_ACTIVE_IN_CHAN_HSCL[1]='H7'

Any change is effective only after the next NCK booting.

CC_FASTON (DIFFON, DIFFOFF [,FEEDTOSWITCH])

CC_FASTON() is a procedure call and must therefore be programmed in a dedicated part

program block.

The parameters for the CC_FASTON() procedure have the following meaning:

* The basic unit (inch or mm) depends on the current dimensions programming (G70 / G71 / G700 /

Default setting.

The calculation of the switching instants is derived

from the first and second geometry axis.

The calculation of the switching instants is derived

from the first, second and third geometry axis.

Length* of the offset distance for setting the switching signal.

Length* of the offset distance for deactivating the switching signal.

This parameter is optional.

If the parameter is not specified in the procedure call, the G0 edge change

is used as the switching criterion.

If the parameter is specified in the procedure call, it contains as a switching

criterion the velocity threshold value, which, when undershot or exceeded,

activates or deactivates the switching signal accordingly.
