Function overview
Rear end move
command
ST0
The actuator will move toward the rear end while this signal
remains at ON level.
Front end move
command
ST1
The actuator will move toward the front end while this signal
remains at ON level.
Intermediate point
move command
ST2
The actuator will move toward the intermediate point while this
signal remains at ON level.
Brake release BKRL
This signal is used on an actuator equipped with a brake to
forcibly release the brake.
Operating mode RMDO
This signal switches the operating mode between AUTO and
MANU.
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.
Rear end detected LS0 This signal will remain ON while the rear end is recognized.
(This signal is not output during push & hold operation.)
Front end detected LS1 This signal will remain ON while the front end is recognized.
(This signal is not output during push & hold operation.)
Intermediate point
detected LS2 This signal will remain ON while the intermediate point is
recognized. (This signal is not output during push & hold
operation.)
Zone 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.
Ready SV
This signal is always output once the servo is turned ON and
the controller is ready to operate.
*Emergency stop *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.
Load output judgment
status
LOAD
This signal will turn ON when the command torque exceeds
the threshold while the actuator is inside the check range.
Note) Dedicated output signal for the PCON-CF
Output
Torque level status TRQS
This signal will turn ON when the motor current reaches the
threshold.
