E6C2-C
Ratings and Specifications
Note: Origin Indication
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.
*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.
