Address	Bits	Name		Function		Controlled
						by
A608	00	High-speed	Target Compar-	OFF: Target value comparison is not being performed for		Module
		counter 1 status	ison In-	CTBL(882).
			progress Flag	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/	OFF: There is no counter overflow or underflow in Linear Counter
			Underflow Flag	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.
	02		Reserved	---
	03		Phase Z Input	ON for one cycle when the counter PV is reset with the counter
			Reset Flag (ON	reset method set to a phase Z + software reset.
			for one cycle)	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	OFF: No error
			Rotations Read	ON: Error
			Error Flag
	05		Absolute No. of	OFF: Rotations being read or reading has not been executed.
			Rotations Read	ON: Reading has been completed (Turned ON when serial recep-
			Completed	tion of the number of rotations has been completed.)
			Flag
	06		Measuring Flag	OFF: Changes in the counter PV or the counter frequency is not
			(measurement	being measured.
			mode 1 or 2)	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.
				Note Valid when Counter Data Display in System Setup is set to
				Counter Movements (mode 1) or Frequency (mode 2).
	07		High-speed	OFF: Counter is not operating.
			Counter Oper-	ON: Counter is operating.
			ating Flag
	08		Count Latched	OFF: Count has not been latched.
			Flag	ON: Latching the count has been completed for the latch input.
	09 to 11		Reserved	---
	12		Absolute Off-	OFF: No error occurred when saving the absolute offset.
			set Preset	ON: An error occurred when saving the absolute offset.
			Error Flag
