SPINDLE FORWARD RUN
[Function]
This signal is output from the high-speed serial connection specification spindle controller (spindle
drive) and informs that the spindle is rotating in the forward direction.
[Operation]
This signal (SSRN) turns ON when the spindle motor is rotating in the forward direction. It also turns
ON even during oriented motion or synchronous tap if the spindle rotates in the forward direction.
Spindle motor speed
Spindle forward run (SSRN)
(Note 1) The "SSRN" signal turns ON and OFF while the spindle motor is in the stop state with
servo features during oriented motion or synchronous tap.
(Note 2) This signal is valid only for the system that is high-speed serially connected with the spindle
controller.

SPINDLE REVERSE RUN
[Function]
This signal is output from the high-speed serial connection specification spindle controller (spindle
drive) and informs that the spindle motor is rotating in the reverse direction.
[Operation]
This signal (SSRI) turns ON when the spindle motor rotates in the reverse direction. It also turns
ON even during oriented motion or synchronous tap if the spindle rotates in the reverse direction.
Spindle motor speed
Spindle reverse run (SSRI)
(Note 1) The "SSRI" signal turns ON and OFF while the spindle motor is in the stop state with
servo features during oriented motion or synchronous tap.
(Note 2) This signal is valid only for the system that is high-speed serially connected with the
spindle controller.
