Maximum electrical response speed (rpm) = Maximum response frequency

Resolution

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

120˚

decrease the output code for CW rotation.
