*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. The quality is equivalent to AM26LS31.
*3. The maximum electrical response speed is determined by the resolution and maximum response frequency as
follows: E6B2-C Specifications 2 This means that the E6B2-C Rotary Encoder will not operate electrically if its speed exceeds the maximum electrical
response speed.
