A280 A280.06 Pulse Output 0
At-origin Flag
ON when the PV of pulse output 0 matches the origin (0).
OFF: Not stopped at origin, ON: Stopped at origin
Retained Cleared • Turned ON when
stopped at the
origin.
• Turned OFF when
the origin is left.
A280.07 Pulse Output 0
Output Stopped
Error Flag
ON when an error occurred while outputting pulses in the pulse
output 0 origin search function. The Pulse Output 0 Output Stop
Error Code will be written to A444.
0: No error, ON: Stop error
Cleared Cleared • Cleared when an
origin search is
started.
• Refreshed when
a fatal pulse out-
put error occurs
during an origin
search.
• Refreshed when
the limit input sig-
nal for pulse out-
put is set to be
always enabled in
the PLC Setup
and pulse output
is stopped due to
the limit input.
• Cleared when
both limit inputs
are disabled and
a fatal pulse out-
put error code is
stored.
A280.08 Pulse Output 0
Interrupt Feed-
ing In-progress
Flag
This flag is turned ON when an interrupt input is received after
output from pulse output 0 is started with the IFEED(892) instruc-
tion.
OFF: Interrupt feeding not in progress.
ON: Interrupt feeding in progress.
Cleared Cleared • Cleared during
overseeing pro-
cessing after
completing inter-
rupt feeding.
• Turned ON when
the interrupt input
turns ON after

started with the
IFEED(892)
instruction.
A280.09 Pulse Output 0
Interrupt Feed-
ing Error Flag
This flag will turn ON if an overflow or underflow occurs when an
interrupt input is received, or when the specified number of pulses
is moved, after output from pulse outputs 0 is started with the
IFEED(892) instruction.
ON: No error.
OFF: Overflow/underflow or specified number of pulses has been
moved.
Cleared Cleared • Cleared when
IFEED(892)
instruction pro-
cessing is
started.
• Turned ON if an
overflow or under-
flow occurs when
an interrupt input
is received, or if
an overflow or
underflow occurs
while the speci-

pulses is being
moved, after
operation is
