*1. An inrush current of approximately 9 A will flow for approximately 0.3 ms when the power is turned ON.
*2. The maximum electrical response speed is determined by the resolution and maximum response frequency as
follows:
　 486_sp_1

This means that the E6A2-C Rotary Encoder will not operate electrically if its speed exceeds the maximum electrical
response speed.
*3. No protection is provided against water or oil.
