*1. When the power is turned on, an inrush current of about 6A flows. (Time: about 0.8ms)
*2. The code is as follows.
| Output Code Rotary Encoders | resolution | Code No. |
|---|---|---|
| binary | 32 | 1–32 |
| 40 | 1–40 | |
| 256 | 0 to 255 | |
| BCD | 6 | 0–5 |
| 8 | 0 to 7 | |
| 12 | 0–11 | |
| Gray Binary | 256 | 0 to 255 |
| 360 | 76 to 435 (76+ grays) | |
| 720 | 152-871 (152+ gray) | |
| 1,024 | 0 to 1,023 |
*3. The maximum electrical response speed is determined by the resolution and maximum response frequency.
![Rotary Encoder Absolute Type Robust Type [E6C3-A] Command-2](http://th.misumi-ec.com/en/linked/vitem/mech/OMR1/221005138888/img/221005138888_003_20230801115855.jpg)
Therefore, if you rotate it beyond the maximum response speed, the signal will not follow electrically.
*4. Rotary Encoders for the E6C3-AN1E and -AN2E, the output code can be increased in the CW direction by connecting the rotation direction specification input (pink wire color) to H (VCC), and decreased in the CW direction
by connecting it to L (0V).
E6C3-AN1E: H = 1.5 to 5 V, L = 0 to 0.8
V E6C3-AN2E: H = 2.2 to 12 V, L = 0 to 1.2 V
Also, for -AN1E and -AN2E, wait 10 μS or more after the LSB (2°) code has changed before reading the code.
*5. Rotary Encoders, The minimum address of the absolute code is output when the position of the D-cut on the shaft and the cable pull-out direction are in the relationship shown in the figure below. (Output position range: ±15°)
*6. Resolution 360, 720: Standard code 2 m
Resolution 256: Standard code 1 m
