3772 Maximum spindle speed
[Input type] Parameter input
[Data type] 2-word spindle
[Unit of data] min
-1
[Valid data range] 0 to 99999999
This parameter sets the maximum spindle speed.
When a command specifying a speed exceeding the maximum speed
of the spindle is specified , or the speed of the spindle exceeds the
maximum speed because of the spindle speed override function, the
spindle speed is clamped at the maximum speed set in the parameter.
CAUTION
1 When 0 is set in this parameter, the speed of the
spindle is not clamped.
2 When spindle speed command control is applied
using the PMC, this parameter has no effect, and
the spindle speed is not clamped.
NOTE
1 For M series, this parameter is valid if the function
of constant surface speed control is provided.
2 When the constant surface speed control option is
selected, the spindle speed is clamped at the
maximum speed, regardless of whether the G96
mode or G97 mode is specified.
Caution
CAUTION
This section mentioned a spindle speed control that
should be prepared on the CNC side. But it is also
necessary to design the signals to the spindle
control unit.
Consult the manual of the spindle control unit used
and take necessary actions on the spindle control
unit.
