          The following illustration shows the relationship between phase Z and the origin. Set cut face D to the phase Z
          origin as shown in the illustration.

E6C2-C Specifications 2

*1. An inrush current of approximately 9 A will flow for approximately 0.3 ms when the power is turned ON.
*2. The line driver output is a data transmission circuit compatible with RS-422A and long-distance transmission is
       possible with a twisted-pair cable.(AM26LS31 equivalent)
*3. The maximum electrical response speed is determined by the resolution and maximum response frequency as
       follows:

E6C2-C Specifications 3

        This means that the E6C2-C Rotary Encoder will not operate electrically if its speed exceeds the maximum electrical
        response speed.
