Instruction manual

Note 1. An inrush current of approx. 9 A flows for approx. 0.1 ms right after the E6C3 is turned on.

2. The line driver output of the E6C3 is used for data transmission circuitry conforming to RS-422A and ensures long-distance transmission

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 E6C3 will not operate electrically if its revolution exceeds the maximum electrical response revolution.

4. JEM1030: applicable since 1991.
