Movement Signal
The positioning to the corresponding target position is
performed, when the signal leading edge created in the
mode change from OFF to ON, or ON level is detected.

[4] [5]
*STP Pause
When this signal is turned OFF while in move, the
actuator decelerates and then stops. The remaining
movement is in a hold while the actuator is stopped and
will resume when the signal turns back ON.
3.8.2 [3]
RES Reset
An alarm will be reset when this signal is turned ON.
(Note) Depending on the alarm level, alarm reset might
not be available. Refer to the Trouble Shooting for
the details.
3.8.2 [3]
SON Servo ON
The servo remains ON while this signal is ON, or OFF
while this signal is OFF.
3.8.2 [1]
SPDC
Movement Speed
Change
To change the speed during a movement operation, input
the movement signal while this signal is ON.
(Note) This signal is available only in the operation
pattern 1.
3.8.2 [10]
CN1 Target Position Change
Turn this signal ON when an operation is made with a
change to the operation condition.
When this signal is turned ON or OFF during the
operation, the position data is changed.
(Note) This signal is available only in the operation
pattern 2.
3.8.2 [11]
Input
ASTR
Continuous
Reciprocating Operation
A back and forth movement is performed repeatedly
between the forward end and the backward end while this
signal is ON. When this signal is turned OFF during the
movement operation, after the actuator is positioned to
the current target, it is stopped.
(Note) This signal is available only in the operation
pattern 5.
3.8.2 [13]
LS0
Backward End Position
Detection
LS1
Forward End Position
Detection
LS2
Intermediate Point
Detection
The same operation as of the limit switch of the air
cylinder is performed.
It is turned ON when the current position is within the
positioning width for each position detection output.
3.8.2 [5]
PE0
Backward End Point
Positioning Completion
PE1
Forward End Point
Positioning Completion
PE2
Intermediate Point
Positioning Completion
This signal is turned ON when the current position goes
within the positioning width, and the positioning to the
target position is complete.
It is turned OFF in the Servo-Motor OFF mode or the
Emergency Stop Mode.
3.8.2 [4]
HEND
Home Return
Completion
This signal will turn ON when home return has been
completed.
It will be kept ON unless the home position is lost.
3.8.2 [6]
SV Servo ON This signal will remain ON while the servo is ON. 3.8.2 [1]
Output
*ALM Alarm Output
This signal remains ON in normal conditions of use and
turns OFF when an alarm is generated.
3.8.2 [2]

Signal with “*” expresses the signal of active low. In the controller, the process is held when the input signal is turned OFF.
