CAN Output [Option | Model: CNT-723-CAN]

Count values can be output via the CAN interface.

7.6¦Ìs High-Speed Analog Output (¡Þ10V / ¡Þ5V)

Calculation speed is within 3.5¦Ìs. Achieves ultra-high-speed response within 7.6¦Ìs from pulse input to isolation, calculation, D/A conversion, and analog output.

3 Types of Measurement Modes

LINEAR Counter

Freely set the full-scale value of the analog output.
Up to ¡Þ47-bit count, suitable for long-term endurance tests.

RING Counter

Repeatedly measures between two arbitrarily set numbers, such as 0 and 360.
Determines forward/reverse rotation with polarized output (¡Þ10V / ¡Þ5V).
Resets at the Z-phase edge, serving as a RING counter with zero cumulative error.

MAG (Magnify)

Measures by magnifying the deviation against the target angle.
For example, to stop at 5¡ë, set the target value to 5¡ë and the range value to
the analog full-scale value to perform magnified measurement during this interval.
Ideal for detailed angle experiments.

3 Types of Displays

Count / Length Measurement

Upper: Full Scale
Lower: Count Value

Rotation Count + Angle Decimal

Upper: Full Scale
Lower: Count Value [Rotation Count]r[Angle]

Rotation Count + DMS (Degree/Minute/Second)

Upper: Full Scale
Lower: Count Value [Rotation Count]r[Degree/Minute/Second]

Reset / Z-Reset

Zero reset and reset to an arbitrary preset value can be performed via button operation, reset signal, or EIA-574 (RS-232C).
Can be reset at edges such as Z-phase, eliminating cumulative errors.

Key Lock

Prevents accidental operation. Reliable even during long-term endurance tests.

Supports Stacking & Panel Mounting

Panel mounting brackets are available for embedded applications.
