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: Maximum response frequency Maximum electrical response speed (rpm) = 60 Resolution 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. 2
