Function
It is necessary to enter the lowest and highest spindle rpm for each gear
range to optimize a machine’s performance. Overlapping ranges are
permitted. The maximum value for a specific gear must be greater than the
minimum value for that gear.
Gear change operations are controlled by the PAL program with gear
change PAL flags. Refer to your PAL reference manual for more
information.
ATTENTION: If the spindle is not capable of attaining the
speed entered for a particular gear range, program execution
may halt and/or an error message results (as determined by the
control’s PAL program).
Values must be entered for all gear ranges specified by the parameter
Number of Gears Used. If any of the gears used has no value or an illegal
value entered here, the control assumes that no gears are available and
never requests a gear change.
