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:

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