3772 Maximum spindle speed
[Data type] 2-word
[Unit of data] min
-1
[Valid data range] 0 to 32767
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.
NOTE
1 For M series, this parameter is valid if the function
of constant surface speed control is provided or
parameter GTT (bit 4 of No. 3706) is set to 1.
2 When the constant surface speed control is
selected, the spindle speed is clamped at the
maximum speed, regardless of whether the G96
mode or G97 mode is specified.
3 When 0 is set in this parameter, the speed of the
spindle is not clamped.
4 When spindle speed command control is applied
using the PMC, this parameter has no effect, and
the spindle speed is not clamped.
5 When the multi-spindle control is selected (T
series), 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.
