(3) Speed detection output (SD)
1) SDT turns ON when the motor speed drops to below that set with parameter SP020 (SDTS).
2) The SDT signal turns ON when the motor speed's absolute value drops to below a set
detection level regardless of the speed command (SRN, SRI).

(4) Orientation complete output (ORCF)
If the current position of the spindle is within the in-position range set with parameter SP004
(OINP) during orientation, ORCF will turn ON.
(5) Current detection output (CD)
CD turns ON when the current value is 110% or more of the rated current.
(6) In motor forward run output (SRNA)
SRNA turns ON when the motor is rotating in the counterclockwise direction looking from the
shaft side.
(7) In motor reverse run output (SRIA)
SRIA turns ON when the motor is rotating in the clockwise direction looking from the shaft side.
(8) In torque limit 1, 2, 3 input (TL1A, TL2A, TL3A)
This is the answer output in respect to the torque limit 1, 2, 3 input (TL1, TL2, TL3).
(9) In orientation start command output (ORCA)
This is the answer output in respect to the orientation start command input (ORC).
