5. I/O Signal Control and Signal Functions
5.2.1 Explanation of Signal Names
The following explains the signal names, and gives a function overview of each signal.
In the explanation of operation timings provided in a later section, each signal is referenced by its self-
explanatory name for clarity. If necessary, however, such as when marker tubes are inserted as a termination of
the flat cable, use the signal abbreviations.

Function overview
PC1
PC2
PC4
PC8
PC16
Command position
number
PC32
The target position number is input.
A command position number must be specified by 6 ms before
the start signal (CSTR) turns ON.
Brake release BKRL
This signal is used on an actuator equipped with a brake to
forcibly release the brake.
Operating mode RMOD
This signal switches the operating mode between AUTO and
MANU.
Home return HOME Home return operation is started at a rise edge of this signal.
*Pause *STP
ON: Actuator can be moved, OFF: Actuator decelerates to a
stop
Start CSTR The actuator will start moving at a rise edge of this signal.
Alarm reset RES An alarm is reset at a rise edge of this signal.
Input
Servo ON SON
The servo remains ON while this signal is ON.
The servo remains OFF while this signal is OFF.
PM1
PM2
PM4
PM8
PM16
Completed position
number
PM32
The relevant position number is output when positioning has
completed.
The signal will turn OFF when the next start signal is received.
It is used by the PLC to check if the commanded position has
definitively been reached, and also to provide a position
interlock, etc.
Moving MOVE
This signal will remain ON while the actuator is moving, and
OFF while the actuator is standing still.
It is used to determine whether the actuator is moving or
paused.
Zone 1 ZONE1
This signal becomes effective after home return. It will turn ON
when the current actuator position enters the range set by the
parameters and remain ON until the actuator exits the range.
Position zone PZONE
This signal becomes effective after a position movement
command is input. It will turn ON when the current actuator
position enters the range specified in the position table and
remain ON until the actuator exits the range.
Operating mode status RMDS
This signal will remain OFF during the AUTO mode, and ON
during the MANU mode.
Home return
completion
HEND
This signal is OFF immediately after the power is input, and
turns ON when home return has completed.
Position complete PEND
This signal turns ON when the target position was reached
and the actuator has entered the specified in-position range.
It is used to determine whether positioning has completed.
Ready SV
This signal is always output once the servo is turned ON and
the controller is ready to operate.
*Emergency stop *EMGS
When this signal is OFF, it means that an emergency stop is
being actuated.
Output
*Alarm *ALM
This signal remains ON in normal conditions of use and turns
OFF when an alarm generates.
