(1)
By using the option, irrespective of the selected mode, this switch
permits overriding the spindle rotation speed in increments
of
10%
from
50%
to
120%.
(2)
The spindle speed in tapping cycles G84 and G74
can be made
unaffected
by this switch (rotated
as
instructed by S-code). This
can
be
accomplished by setting
parameters (Pm2000 D2=0: override
not
100% clamped or D2=l:
override 100% clamped).
(3)
In addition
to
50%
to
120% override of S-code, an extended function is
available
by an option
that permits override in the
range
of 10%
to
200%.
