13.7.9 Orientation Operation During Spindle-Mode Rotary Axis Control Mode

If an orientation command is given during rotation, and the orientation direction is identical to the rotation direction, the spindle
decelerates multi-step-wise as illustrated below. After the spindle reaches the speed of "#3107 ori_spd (Orientation command
speed)", it decelerates with a constant inclination, and stops in the orientation position.
Orientation that starts during rotation
PLC -> NC
S1 spindle orientation command (ORC: Y189E)
NC -> PLC
S1 spindle in-position (ORAO: X188E)
(1) Turn ON the spindle orientation command signal (ORC: Y189E).
(2) Decelerate multi-step-wise to the "#3107 ori_spd (Orientation command speed)" in the rotation direction.
(3) The motor decelerates at a constant inclination during orientation.
Inclination = Orientation speed #3107 ori_spd (rpm) / Time constant #3115 sp2_t1 (ms)
(4) Decelerate to a stop in the servo motor's machine zero point. (or the shifted position if "#3108 ori_sft (Position shift
amount for orientation)" is set)
(5) Turn ON the spindle in-position signal (ORAO: X188E).
