[3] List of PIO Signals
The table below lists the functions of PIO signals. Refer to the section shown in Relevant
Sections for the details of the control of each signal.
Category
Signal
Abbreviation
Signal Name Function Description
Relevant
Sections
EMG Emergency Stop Input It shuts the motor power supply. 4.2.2 [3]
BK Brake Forcible Release The brake will forcibly be released. 4.2.2 [4]
CSTR Start Signal
The actuator will start to move to the position set by the
command position number.
4.2.2 [7]
PC1 to PC8 Command Position
Number
Input of the position number to move (binary input) 4.2.2 [7]
*STP Pause
When this signal turns OFF while the actuator is moving,
the actuator will decelerate to stop. The remaining
movement is retained and will resume when the signal is
turned ON again.
4.2.2 [7]
HOME Home Return
The controller will perform home return operation when
this signal is turned ON.
4.2.2 [6]
Input
ST0 to ST6 Start Signal
The actuator moves to the position corresponding to the
start signal when this signal is on in Electromagnetic
Valve Mode.
4.2.2 [8]
PEND Position Complete
Turns ON in the positioning width range after actuator
operation. The INP signal will turn OFF if the position
deviation exceeds the in-position range. PEND and INP
can be switched over by the parameter.
4.2.2 [6] [7]
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.
4.2.2 [6] [7]
ZONE1 Zone Signal 1
Turns ON if the current actuator
position is within the range set to the
parameter No.1, 2.
4.2.2 [6]
PZONE Position Zone
This is a function belonging to the
commanded position number, and the
zone range is to be set in the position
table and is effective only when that
position is indicated. This signal turns
ON when the current position comes
into the range set in the position data.
For PIO Pattern 2,
the mode can be
switched over
between ZONE1
and PZONE with
Parameter No.
149.

PZONE)
4.2.2 [6]
*ALM Alarm
Turns ON when the controller is in normal condition, and
turns OFF when an alarm is generated.
4.2.2 [6]
Output
PE0 to PE2 Current Position
Number
In the electromagnetic valve mode, this signal will turn
ON when the actuator completes moving to the target
position.
