(1) COMOA Power for input port
(2) COMOB
Power for input port
Connect a DC24 V potential across COMOA & COMOB, for output functionality.
Polarity does not exist between COMOA & COMOB.
Pin Numbers. 1 and 2 are connected internally and Pin Numbers. 3 and 4 are also
connected internally.
(3) During Transfer Turns on during transfer. When you want to detect holding motor during hold, use this
signal.
(4) Emergency Stop
Turns off at emergency stop. During normal operation, stays ON.
A normal condition is restored once the emergency stop is cancelled.
(5) Alarm
Turns OFF during an alarm. During normal operation, stays ON. For homing, execute
reset input or cycle power, after alarm factor is solved.
(6) Zone
Outputs within range set in the parameter.
(7) Homing Complete
Upon applying power, turns ON once initial homing completes. Afterwards, as long as
alarm does not occur and power does not turn OFF, continues to stay ON. This will not
turn OFF simply by emergency stop input. Turning the home complete signal OFF
means homing is executed prior to this next movement:
Caution: With the absolute specifications, once absolute reset is executed, upon applying power, homing
complete signal will turn ON. In case homing complete signal turns OFF due to an alarm occurrence,
you will need to execute absolute reset again.
(8) Positioning Complete Upon applying power, once the operation preparation completes, turns ON. Turns
OFF upon start signal input. Turns ON once movement completes. The timing for the
positioning complete ON and Complete position output are the same.
(9) Battery
Alarm With the absolute specifications, this signal turns OFF when the backup battery voltage
drops to 3.1 V or below (battery alarm is a contact-B signal and remains ON in normal
condition). It indicates that the battery must be replaced soon. When a battery alarm
generates, operation is not disabled immediately. Following a battery alarm, the battery
will last for approx. 220 hours (approx. 9 days) before a battery error occurs.
Note) The battery alarm function is available with H2 and later versions of controllers.
The battery alarm signal remains OFF with the incremental specification.
