- 201 -
3770 Axis as the calculation reference in constant surface speed control
[Input type] Parameter input
[Data type] Byte path
[Valid data range] 0 to Number of controlled axes
Set the axis as the calculation reference in constant surface speed
control.
NOTE
When 0 is set, constant surface speed control is
always applied to the X-axis. In this case,
specifying P in a G96 block has no effect on the
constant surface speed control.
3771 Minimum spindle speed in constant surface speed control mode (G96)
[Input type] Parameter input
[Data type] 2-word path
[Unit of data] min
-1
[Valid data range]
Set the minimum spindle speed in the constant surface speed control
mode (G96).
The spindle speed in constant surface speed control is clamped to the
speed given by parameter 3771.
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.
