Diagnostic bits

Bit 22: Position was changed during power

drop

Bit 23: Positioning element has reached

the end of the measuring range. This is

indicated by a lower signal quality.

Bit 24: Positioning element is outside the

measuring range.

Data messages parametrizable as

multiturn and singleturn process data or

error bits

Functional principle

The measuring principle of inductive encoders

is based on oscillation circuit coupling

between the positioning element and the

sensor, whereby an output signal is provided

proportional to the angle of the positioning

element. Turck refers to semi-multiturn because

the multiturn process data is calculated

internally from the number of single-turn

zero passes. Because the sensor does not

detect any revolutions when not supplied

with power, the plausibility of the multiturn

process data is indicated by a diagnostic

bit. The rugged sensors are maintenance-

and wear-free thanks to the contactless

operating principle. They convince through

their excellent repeatability, resolution and

linearity within a broad temperature range. The

innovative technology ensures high immunity to

electromagnetic DC and AC fields.
