13.7.5 Operations at Switchover from Spindle-Mode Rotary Axis to Servo Axis Mode

There are two types operations to be performed when the mode is switched from spindle-mode rotary axis control to servo
axis control.
 Zero point return type: (Parameter "#3106 zrn_typ/bit8" = "0")
The rotary axis is positioned in its machine zero point by turning OFF the spindle-mode rotary axis control command signal.
Use the parameters "#3106 zrn_typ/bit9" to "#3106 zrn_typ/bitA" to select the specifications of zero point return (short-cut,
forward run or reverse run) when the return is performed while the spindle is at a standstill.

 Deceleration stop type: (Parameter "#3106 zrn_typ/bit8" = "1")
When you turn OFF the spindle-mode rotary axis control command signal with the spindle at a stand still, the servo axis
control mode is enabled, and the machine value counter shows a position from the machine origin.
When you turn OFF the spindle-mode rotary axis control command signal with the spindle rotating, the spindle decelerates to
a stop, and switches to servo axis control mode . The machine value counter shows a position from the machine origin.
