Function overview
PC1

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.
Operation mode MODE Mode selection (ON: Teaching mode, OFF: Normal mode)
Jog/inching switching JISL OFF: Jog, ON: Inching
+jog/inching movement JOG+
The actuator will start jogging or inching in the positive direction at an
ON edge of this signal.
-jog/inching movement JOG-
The actuator will start jogging or inching in the negative direction at an
ON edge of this signal.
Operating mode RMOD
This signal switches the operating mode between AUTO and
MANU.
(ON: MANU, OFF: AUTO)
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.
Current-position write PWRT
When this signal has remained ON for 20 msec or longer, the current
position will be stored under the position number selected by PC1 to
PC32.
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.
Used to check the operation or determine if the load was missed in
push & hold operation.
Mode status MODES
This signal is ON when the controller is in the teaching mode, and
OFF when the controller is in the normal mode.
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 A signal indicating the operating mode of AUTO or MANU is output.
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 actuator has moved to the target
position and entered the positioning band. It is used to determine if
the positioning has completed.
Write completion WEND
This signal is output upon completion of writing to the nonvolatile
memory in response to a current-position write command (PWRT).
Servo-on status SV
This signal is always output once the servo is turned ON and the
controller is ready to operate.
Emergency stop status *EMGS OFF: Emergency stop has been actuated
Alarm *ALM
This signal remains ON in normal conditions of use and turns OFF
when an alarm generates.
Output
Battery alarm *BALM
This signal is ON when the absolute battery voltage is normal or an
incremental encoder is used.
