13.7.3 Function Enabling Conditions

Given below is a configuration example where B axis (S2 spindle) is the objective of spindle-mode rotary axis control.
X axis Y axis Z axis B axis
CNC
Servo motors
(1) Specify the number of control axes.
If you enable the spindle-mode rotary axis control, you need to set the spindle. For one servo motor, set one rotary axis
and one spindle.
In this example
[#1024(PR)] axisno (number of axes) = 4 (X, Y, Z and B)
[#1039(PR)] spinno = 2 (S1 and S2) Add 1 to the number of spindles.
(2) Configure the parameters to enable the spindle-mode rotary axis control.

#1020 sp_ax 0

<Servo axis (B axis) settings>
 Spindle-mode rotary axis setting
Set the parameter "#1020 sp_ax" (Spindle interpolation) to "2".
When you have changed the setting of the parameter "#1020 sp_ax", turn ON the NC again, then reestablish the zero
point.
 Rotary axis setting
Set the parameter "#1017 rot" (Rotational axis) to "1".
<Spindle (S2) settings>
 Setting of spindle not connected to drive
Set the parameter "#3024 sout" (Spindle connection) to "0".
 Setting of spindle-mode rotary axis objective
Set the parameter "#3031 smcp_no" (Drive unit I/F channel No. (spindle)) to be the same as the drive I/F in "#1021
mcp_no" (Drive unit I/F channel No. (servo) of B axis.
Note
 Select the rotation type rotary axis for the rotary axis spindle ("#8213 Rotation axis type" is set to "0" or "1").
