		mand bits
	01			Reset Bit	OFF: If a software reset is set in the System Setup, the counter PV
					will not be reset when internal I/O is refreshed in the Motion Con-
					trol 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 Control
					Module. If a phase Z + software reset is set, enables the phase Z
					input.
	02			Measurement	OFF: Disables measuring changes in counter PV or the counter
				Start Bit	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	OFF: Forward (up)
				Direction Bit	ON: Reverse (down)
				(measurement	This bit specifies the up/down direction of the pulse input for fre-
				mode 2)
					quency measurement.
					Note Always set this bit before turning ON the Measurement Start
					Bit.
	04			Range Com-	OFF: Does not clear the execution results (A612) or output bit pat-
				parison Results	tern (A613) from CTBL(882) execution for range comparison for
				Clear Bit	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 Off-	OFF: Does not preset the offset.
				set Preset Bit	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	OFF: Disables the absolute present value preset.
				Present Value	OFF to ON: Stores the Absolute PV in the counter 1 PV (A600 and
				Preset Bit	A601).
					Note Refer to 7-7-6 Absolute Present Value for details on the
					absolute PV.
	07			Absolute Num-	OFF: Disables reading the number of rotations data from the Servo
				ber of Rota-	Driver.
				tions Read Bit	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	OFF: Disables the external latch input 1 signal.
				Enable Bit	ON: Enables the external latch input 1 signal.
	09			Latch Input 2	OFF: Disables the external latch input 2 signal.
				Enable Bit	ON: Enables the external latch input 2 signal.
