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.
WARNING
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 In the M series, this parameter is valid only when the
constant surface speed control is present.
2 When the constant surface speed control is present, the
spindle speed is clamped at the maximum speed,
regardless of whether the G96 mode or G97 mode is
specified.
3 When the multi–spindle control option is present, set the
maximum speed for each spindle in the following
parameters:
Parameter No. 3772: Sets the maximum speed for the first
spindle.
Parameter No. 3802: Sets the maximum speed for the
second spindle.
Parameter No. 3822: Sets the maximum speed for the third
spindle.
