This means that the Rotary Encoder will not operate electrically if its speed exceeds the maximum
electrical response speed.
*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
