A275 00 High-speed Counter 1
Range 1 Comparison
Condition Met Flag
These flags indicate whether the PV is
within the specified ranges when
high-speed counter 1 is being operated
in range-comparison mode for upper
and lower limits.
• Cleared when operation starts.
• Cleared when range comparison
table is registered.
OFF: PV not in range
ON: PV in range
Cleared • Refreshed
each cycle
during over-
seeing pro-
cess.
• Refreshed
when PRV
instruction is
executed to
read the
comparison
results for
the corre-
sponding
counter.

In-progress Flag
This flag indicates whether a compari-
son operation is being executed for
high-speed counter 1.
• Cleared when operation starts.
OFF: Stopped.
ON: Being executed
Cleared Refreshed
when compari-
son operation
starts or stops.
09 High-speed Counter 1
Overflow/Underflow
Flag
This flag indicates when an overflow or
underflow has occurred in the
high-speed counter 1 PV. (Used with
the linear mode counting range only.)
• Cleared when operation starts.
• Cleared when the PV is changed.
OFF: Normal
ON: Overflow or underflow
Cleared Refreshed
when an over-
flow or under-
flow occurs.
10 High-speed Counter 1
Count Direction
This flag indicates whether the
high-speed counter 1 is currently being
incremented or decremented. The
counter PV for the current cycle is com-
pared with the PV in last cycle to deter-
mine the direction.
OFF: Decrementing
ON: Incrementing
Cleared Setting used
for high-speed
counter, valid
during counter
operation.
A276 Pulse Out-
put 0 PV
Lower four
digits
Contain the number of pulses output
from the corresponding pulse output
port.
PV range: 8000 0000 to 7FFF FFFF
hex
(-2,147,483,648 to 2,147,483,647)
When pulses are being output in the
CW direction, the PV is incremented by
1 for each pulse.
When pulses are being output in the
CCW direction, the PV is decremented
by 1 for each pulse.
PV after overflow: 7FFF FFFF hex
PV after underflow: 8000 000 hex
• Cleared when operation starts.
Note If the coordinate system is rela-
tive coordinates (undefined ori-
gin), the PV will be cleared to 0
when a pulse output starts, i.e.
when a pulse output instruction
(SPED, ACC, or PLS2) is exe-
cuted.
Cleared • Refreshed
each cycle
during the
overseeing
processes.
• Refreshed
when the INI
instruction is
executed
(PV
change).
