Configuration

4.3.1

Operating modes and parameters

The module has the following configuration options:

Configuration

Default

value

Meaning

Operating mode

Incremental encoder operating mode
Counter operating mode

Signal for gate input

Input G disables at a 1 signal
Input G disables at a 0 signal

Period length measure-

ment or latch function

Latch function
Period length measurement

Multiple evaluation

Quadruple evaluation
Double evaluation
Single evaluation

Status input

The status at input S is transmitted via a bit.
The status is transmitted via two redundant bits.
The status is transmitted via two diverse bits.

(1)

Transmitting the status via two bits enables simple fault detection: Two redundant bits

must always be the same, two diverse bits must always be different, otherwise the trans-
mission is faulty.
