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 RMOD
This signal switches the operating mode between AUTO and MANU.
(ON: MANU, OFF: AUTO)
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 position
detected
LS0
This signal will remain ON while the rear end is recognized.
(This signal is not output in the push & hold mode.)
Front end position
detected
LS1
This signal will remain ON while the front end is recognized. (This
signal is not output in the push & hold mode.)
Intermediate position
detected
LS2
This signal will remain ON while the intermediate point is recognized.
(This signal is not output in the push & hold mode.)
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 when the current actuator position is in
the range specified in the position table, while a position movement
command is input.
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.
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.
Take note that incremental position commands are not supported in solenoid valve mode 2 [3-point type].
