11.SPINDLE SPEED FUNCTION B-63943EN-1/02
- 1264 -
The spindle speed is limited to the upper limit of spindle speed
specified in parameter No. 3772, irrespective of the setting of this
parameter.
#7 #6 #5 #4 #3 #2 #1 #0
3709 RSC
[Input type] Parameter input
[Data type] Bit path
# 1 RSC In the constant surface speed control mode, the surface speed of a
rapid traverse block is calculated:
0: In accordance with the coordinates of the end point.
1: In accordance with the current value, as in cutting feed.
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.
