		status
					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		ON for one cycle when the counter PV is reset with the counter
			one cycle)		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		OFF: No error
			Flag		ON: Error
	05		Absolute No. of Rotations Read		OFF: Rotations being read or reading has not been executed.
			Completed Flag		ON: Reading has been completed (Turned ON when serial recep-
					tion of the number of rotations has been completed.)

	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.
