CAN output option [CNT-723-CAN]
　Outputs count values from CAN interface.

7.6μs high-speed analog output (±10V/±5V)
　Calculation speed is within 3.5μs. High-speed response within 7.6μs from pulse input to isolation, calculation, D/A conversion, and analog output.

3 measurement modes

LINEAR counter		RING counter		MAGNIFY
Full scale value of analog output can be freely set. Maximum ±47 bit count, for long time endurance test.		Repeated measurement between two arbitrarily set values, such as 0 and 360. Polarized output (±10V/±5V) to determine forward/reverse rotation. Reset on Z-phase edge for RING counter with no accumulated error.		Enables measurement with expanded misalignment with respect to the target angle. For example, when stopping at 5°, the center value is set to 5° and the allowable value to the analog full scale value, and the measurement can be expanded between these values. This is ideal for detailed angle experiments.

3 types of display

Count/length measurement		Rotation count + angle decimal point		Rotation count + degree minute second
Upper row: Full scale Lower row: Count value		Upper: Full scale Lower: [Rotation count]r[angle]		Upper: Full scale Lower: [Rotation count]r[angle°minute' second"]

Reset / Z-reset
　Zero reset and reset to any set value can be performed by button operation, reset signal, or EIA-574 (RS-232C).
　Can be reset at the edge of Z-phase, etc., with no accumulated error.

Key lock
　Prevents accidental operation. Safe for long-time endurance tests.

EIA-574 (RS-232C) communication
　Count value reading/resetting and setting change.
