A56 00 Pulse Output 2
Accel/Decel Flag
This flag will be ON when pulses are
being output from pulse output 2
according to an ORG, ACC, PLS2,
ITPL or IFEED instruction and the
output frequency is being changed in
steps (accelerating or decelerating).
ON: Accelerating or
decelerating
OFF: Constant speed
--- Cleared Refreshed
each cycle
during the
overseeing
processes.
01 Pulse Output 2
Overflow/Underflow
Flag
This flag indicates when an overflow or
underflow has occurred in the pulse
output 2 PV.
ON: Overflow or
underflow
OFF: Normal
--- Cleared • Refreshed
when the PV
is changed
by the INI
instruction.
• Refreshed
when an
overflow or
underflow
occurs.
02 Pulse Output 2 Output
Amount Set Flag
ON when the number of output pulses
for pulse output 2 has been set with the
PULS instruction.
ON: Setting made
OFF: No setting
--- Cleared • Refreshed
when the
PULS
instruction is
executed.
• Refreshed
when pulse
output stops.
03 Pulse Output 2 Output
Completed Flag
ON when the number of output pulses
set with the PULS, PLS2, ITPL or
IFEED instruction has been output
through pulse output 2.
ON: Output
completed
OFF: Output not
completed
--- Cleared Refreshed at
the start or
completion of
pulse output.
04 Pulse Output 2 Output
In-progress Flag
ON when pulses are being output from
pulse output 2.
ON: Outputting
pulses
OFF: Stopped
--- Cleared Refreshed
when pulse
output starts or
stops.
05 Pulse Output 2
No-origin Flag
ON when the origin has not been
determined for pulse output 2 and goes
OFF when the origin has been
determined.
ON: Origin not
established
OFF: Origin
established
ON ON Refreshed
each cycle
during the
overseeing
processes.
06 Pulse Output 2
At-origin Flag
ON when the pulse output 2 PV
matches the origin (0).
ON: Stopped at origin
OFF: Not stopped at
origin
--- Cleared Refreshed
each cycle
during the
overseeing
processes.
07 Pulse Output 2 Output
Stopped Error Flag
ON when an error occurred while out
putting pulses in the pulse output 2
origin search function.
The Pulse Output 2 Output Stop Error
code will be written to A438.
ON: Stop error
occurred
OFF: No error
--- Cleared • Refreshed
when origin
search
starts.
• Refreshed
when a
pulse output
stop error
occurs.

08 Pulse Output 2
Interrupt Feeding Flag
ON between Input Interrupt -
decelerating to stop when Interrupt
Feed

unction (IFEED instruction) is
executing.
ON: Feeding
OFF: Not feeding
Cleared Cleared • Refreshed
when feed-
ing is com-
pleted.
• Refreshed
when inter-
rupt feeding
is executing.
09 Pulse Output 2
Interrupt Feeding Error
Flag
ON if an overflow or underflow error
occurs during input interrupt or
specified number of pulse output, when
Interrupt Feeding function (IFEED
instruction) is executing.
ON: Overflow or
underflow
OFF: Normal
Cleared Cleared Refreshed
when interrupt
feeding is
executing.
