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°).
