Spindle 1 Parameters
Chapter 12
12-9
Function
This parameter specifies the number of available spindle gear ranges for a
specific machine application. The control allows for 8 spindle gear ranges.
Important: If the machine does not have multiple spindle gear ranges,
enter 1 for this parameter.
Spindle Parameter
Number
1 [860]
Range
0 to 8
Notes
Actual spindle gear changing is implemented through PAL. When PAL
sets the gear mode request flag to “automatic,” the control uses this
parameter and the other AMP gear parameters to determine the correct
gear for the commanded spindle speed. It then requests gear changes from
PAL as needed. Refer to your PAL reference manual for more
information.
This parameter must be set for each spindle axis.
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).
