SPEED/MULTIPLY Selects anaxis feedrateor axis feedamount multiplication ratioused inthe manual mode. Each
selection modifies the activefeedrate bya value set in AMP. Modification alsodepends onthe setting
of <JOG SELECT> asdescribed below:
· HANDWHEEL
When in handwheel jogmode, SPEED/MULTIPLY alters thehandwheel resolutionby a factor
determined in AMP. Your system installer sets thevalue for:
- LOW X1
- MEDLX10
- MEDLX100
You cannot use the values listed below for handwheel jog:
- MEDHX1000
- HIGHX10000
· INCREMENTAL
When in incremental jogmode, SPEED/MULTIPLY alters theincremental jogdistance bya factor set
in AMP by your system installer. Your system installer sets avalue forthe selections. The
incremental jogspeed isfixed tomedium but canstill be controlled by
<FEEDRATE OVERRIDE>.
· CONTINUOUS
When in continuous jogmode, SPEED/MULTIPLYacts asa feedrateselection switchwhich has
values set inAMP byyour system installer. Your system installer sets avalue forall 5selections
independently foreach axis. <FEEDRATE OVERRIDE> can beused for speedadjustments.
Important: The values for the different <SPEED/MULTIPLY> selectionsare configuredby
your system installer.
SPINDLE SPEEDOVERRIDE Selects theoverride forprogrammed spindle speeds in5% incrementswithin arange of 50%to 120%.
SPINDLE or
SPINDLE DIRECTION
Selects spindlerotation, clockwise (CW), spindlestop (OFF), counterclockwise(CCW). Can be
overridden by any programmedspindle directioncommand.
FEEDRATE OVERRIDE Selects afeedrate overridepercentage forthe feedrate programmed with anF wordin anyof the
feedrates modes(G93/G94/G95) and the reciprocationfeedrate programmedwith anE word.
<FEEDRATE OVERRIDE> has arange of 0% to150% of theprogrammed feedrateand altersthe
programmed feedrate in 10% increments. When set to0%, the controlis effectively infeedhold.
RAPID FEEDRATE OVERRIDE Selectsthe override for rapidfeedrates. Select from F1, 25%, 50%, and 100%where F1is arapid
feedrate override setting established inAMP by thesystem installer.
