Ratings/Characteristics
Note: 1.
An inrush current of approx. 9 A flows for approx. 0.3 ms right after the E6C2-C is turned on.
2.
The line driver output of the E6C2-C is used for data transmission circuitry conforming to RS-422A and ensures long-distance transmis-
sion over twisted-pair cable, the quality of which is equivalent to AM26LS31.
3.
The maximum electrical response revolution is determined by the resolution and maximum response frequency as follows:
Maximum electrical response frequency (rpm) = Maximum response frequency/resolution
×
60
This means that the E6C2-C Rotary Encoder will not operate electrically if its revolution exceeds the maximum electrical response revo-
lution.
4. Origin Indication
It is easy to adjust the position of phase Z with the origin indication function. The following illustration (on the left side) shows the rela-
tionship between phase Z and the origin. Set cut face D to the origin as shown in the illustration (on the right side).
