Omron FQM1-MMA21, FQM1-CM001, FQM1-MMP21 Auxiliary Area Allocations, Appendix D, A610

Auxiliary Area Allocations				Appendix D
Address	Bits		Name	Function
A610	00	High-	Start Bit	OFF: Stops counter operation. The counter PV will be main-
		speed		tained.
		counter 1		ON: Starts counter operation. The counter PV will be reset.
		com-
	01		Reset Bit	OFF: If a software reset is set in the System Setup, the counter
		mand
		bits		PV will not be reset when internal I/O is refreshed in the Motion
				Control Module. If a phase Z + software reset is set, disables the
				phase Z input.
				ON: If a software reset is set in the System Setup, resets the
				counter PV to 0 when internal I/O is refreshed in the Motion Con-
				trol Module. If a phase Z + software reset is set, enables the
				phase Z input.
	02		Measurement Start Bit	OFF: Disables measuring changes in counter PV or the counter
				frequency.
				ON: Starts measuring changes in counter PV or the counter fre-
				quency.
				Note Measuring the high-speed counter frequency is possible
				only for high-speed counter 1.
				Note Valid when Counter Data Display in System Setup is set to
				Counter Movements (mode 1) or Frequency (mode 2).
	03		Measurement Direction Bit (mea-	OFF: Forward (up)
			surement mode 2)	ON: Reverse (down)
				This bit specifies the up/down direction of the pulse input for fre-
				quency measurement.
				Note Always set this bit before turning ON the Measurement
				Start Bit.
	04		Range Comparison Results Clear Bit	OFF: Does not clear the execution results (A612) or output bit
				pattern (A613) from CTBL(882) execution for range comparison
				for the counter.
				ON: Clears the execution results (A612) or output bit pattern
				(A613) from CTBL(882) execution for range comparison for the
				counter.
	05		Absolute Offset Preset Bit	OFF: Does not preset the offset.
				OFF to ON: Stores the number of multi-turns read from the Servo
				Driver and the number of initial incremental pulses as an offset in
				the Absolute Offset value in the System Setup.
				When establishing the machine origin, the position from the abso-
				lute encoder origin is set as the Absolute Offset in the System
				Setup as the machine origin.
	06		Absolute Present Value Preset Bit	OFF: Disables the absolute present value preset.
				OFF to ON: Stores the Absolute PV in the counter 1 PV (A600
				and A601).
				Note Refer to 7-7-6 Absolute Present Value for details on the
				absolute PV.
	07		Absolute Number of Rotations Read	OFF: Disables reading the number of rotations data from the
			Bit	Servo Driver.
				OFF to ON: Outputs the SEN output to the Servo Driver and
				receives the number of rotations data on the phase A input.
	08		Latch Input 1 Enable Bit	OFF: Disables the external latch input 1 signal.
				ON: Enables the external latch input 1 signal.
	09		Latch Input 2 Enable Bit	OFF: Disables the external latch input 2 signal.
				ON: Enables the external latch input 2 signal.
A611	00	High-	Start Bit	Same as command bits for high-speed counter 1.
