Function
ON when the PV of pulse output 0 matches the origin (0).
OFF: Not stopped at origin, ON: Stopped at origin
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
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.
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.

Retained Cleared • Turned ON when
stopped at the
origin.
• Turned OFF when
the origin is left.
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.

both limit inputs
are disabled and
a fatal pulse out-
put error code is
stored.
Cleared Cleared • Cleared during
overseeing pro-
cessing after
completing inter-
rupt feeding.

the interrupt input
turns ON after
pulse output is
started with the

instruction.
Cleared Cleared • Cleared when
IFEED(892)

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-
fied number of
pulses is being
moved, after
operation is
started with the
IFEED(892)
instruction with
the origin defined.
