*1. An inrush current of approximately 6 A will flow for approximately 0.8 ms when the power is turned ON.
*2. The code is as follows:

Output code Resolution Code No.
Binary 32 1 to 32
40 1 to 40
256 0 to 255
BCD 6 0 to 5
8 0 to 7
12 0 to 11
Gray 256 0 to 255
360 76 to 435 (gray after 76)
720 152 to 871 (gray after 152)
1024 0 to 1,023

*3. The maximum electrical response speed is determined by the resolution and maximum response frequency as
       follows:

E6C3-A Specifications 4

*4. For the E6C3-AN1E and E6C3-AN2E, the rotation direction input (wire color: pink) can be connected to high (Vcc) to
       increase the output code for CW rotation and connected to low (0 V) to decrease the output code for CW rotation.
       E6C3-AN1E: High = 1.5 to 5 V, Low = 0 to 0.8 V
       E6C3-AN2E: High = 2.2 to 12 V, Low = 0 to 1.2 V
       Read the code 10 μs or more after the LSB (20) of the code changes for the E6C3-AN1E or E6C3-AN2E.
*5. The minimum address of the absolute code is output when cut face D on the shaft and the cable connection direction
       are as shown in the diagram at the right (output position range: ±15°).
*6. Resolution of 360 or 720: Standard cable length: 2 m
       Resolution of 256: Standard cable length: 1 m
