Same as for A604 and A605 for high-speed counter 1 except that
measuring the high-speed counter frequency is not possible for
high-speed counter 2.

Target Comparison In-progress Flag
OFF: Target value comparison is not being performed for
CTBL(882).
Note This flag is always OFF for range comparison.
ON: Target value comparison is being performed for CTBL(882).
Note Target comparison is continued without interruption once it
has been started (as opposed to range comparison), so this flag
can be used to check whether target comparison is in progress.
01
PV Overflow/Underflow Flag
OFF: There is no counter overflow or underflow in Linear Counter
Mode. This flag will always be OFF in Circular Counter Mode.
ON: There is a counter overflow or underflow in Linear Counter
Mode. The counter PV will be fixed at the overflow or underflow
limit. This flag will be cleared when the High-speed Counter Start
Bit is turned OFF.
03
Phase Z Input Reset Flag (ON for
one cycle)
ON for one cycle when the counter PV is reset with the counter
reset method set to a phase Z + software reset.
Note This flag will turn ON for one cycle after the counter PV is
reset if the phase Z signal (reset input) turns ON while the High-
speed Counter Reset Bit (A610.01) is ON.
04
Absolute No. of Rotations Read Error
Flag
OFF: No error
ON: Error
05
Absolute No. of Rotations Read
Completed Flag
OFF: Rotations being read or reading has not been executed.
ON: Reading has been completed (Turned ON when serial recep-
tion of the number of rotations has been completed.)
06
Measuring Flag (measurement mode
1 or 2)
Note Valid when Counter Data Dis-
play in System Setup is set to
Counter Movements (mode 1) or Fre-
quency (mode 2).
OFF: Changes in the counter PV or the counter frequency is not
being measured.
ON: Changes in the counter PV or the counter frequency is being
measured.
In measurement mode 1, this flag will turn ON at the beginning of
the sampling time after the Measurement Start Bit (A610.02) is
turned ON.
07
High-speed Counter Operating Flag
OFF: Counter is not operating.
ON: Counter is operating.
08
Count Latched Flag
OFF: Count has not been latched.
ON: Latching the count has been completed for the latch input.
12
Absolute Offset Preset Error Flag
OFF: No error occurred when saving the absolute offset.
ON: An error occurred when saving the absolute offset.
