SPINDLE IN-POSITION
[Function]
This signal is output from the high-speed serial connection specification spindle controller (spindle
drive) and informs that the spindle is positioned in the set range in accordance with spindle orient
command.
[Operation]
When the spindle positioning in the set range completes, this signal will turn ON. The spindle
orientation is stored by "Spindle orient command" signal (ORC).
(1) The in-position range is set with the spindle parameters.
(2) While the spindle is in position, it is under servo lock condition. However, if the spindle is rotated
by external force, the signal (ORAO) may be turned OFF.
(3) The signal is turned OFF when the "Spindle orient command" (ORC) is turned OFF.

(Note 1) When spindle orient command is given, orientation starts regardless of the "Spindle
forward run start (SRN)" or "Spindle reverse run start (SRI)".
(Note 2) Range of in-position can be set within range from 0.001 to 99.999 degrees.
(Note 3) This signal is valid only for the system that is high-speed serial connected with the
controller.
