10. SPINDLE SPEED FUNCTION

- 1570 -
To determine a plane for circular interpolation, cutter compensation, and so forth (G17:
Xp-Yp plane, G18: Zp-Xp plane, G19: Yp-Zp plane), specify which of the basic three
axes (X, Y, and Z) is used for each control axis, or a parallel axis of which basic axis is
used for each control axis.
A basic axis (X, Y, or Z) can be specified only for one control axis.
Two or more control axes can be set as parallel axes for the same basic axis.
Setting
Meaning
0
Rotary axis (Neither the basic three axes nor a parallel axis )
1
X axis of the basic three axes
2
Y axis of the basic three axes
3
Z axis of the basic three axes
5
Axis parallel to the X axis
6
Axis parallel to the Y axis
7
Axis parallel to the Z axis
In general, the increment system and diameter/radius specification of an axis set as a
parallel axis are to be set in the same way as for the basic three axes.
For a Cs contouring control, set 0.
1023
Number of the servo axis for each axis
NOTE
When this parameter is set, the power must be turned off before
operation is continued.
[Input type] Parameter input
[Data type] Byte axis
[Valid data range] 0 to 80
This parameter associates each control axis with a specific servo axis. Specify values
1+8n, 2+8n, 3+8n, 4+8n, 5+8n, and 6+8n (n = 0, 1, 2, …, 9) like 1, 2, 3, 4, 5, …, 77, and
78.
The control axis number is the order number that is used for setting the axis-type
parameters or axis-type machine signals
With an axis for which Cs contour control/spindle positioning is to be performed, set
-(spindle number) as the servo axis number.
Example)When exercising Cs contour control on the fourth controlled axis by using the
first spindle, set -1.
1260
The shift amount per one rotation of a rotary axis
NOTE
When this parameter is set, the power must be turned off before
operation is continued.
[Input type] Parameter input
[Data type] Real axis
[Unit of data] deg
[Min. unit of data] Depend on the increment system of the applied axis
[Valid data range] 0 or positive 9 digit of minimum unit of data (refer to the standard parameter setting table
(B))
(When the increment system is IS-B, 0.0 to +999999.999)
Set the shift amount per one rotation of a rotary axis.
