Electrical connection

Incremental signals  TTL

HEIDENHAIN encoders with  TTL

interface incorporate electronics that

digitize sinusoidal scanning signals with or

without interpolation.

The incremental signals are transmitted

as the square-wave pulse trains U

and

, phase-shifted by 90° elec. The

reference mark signal consists of one or

more reference pulses U

, which are

gated with the incremental signals. In

addition, the integrated electronics produce

their inverted signals ,  and  for

noise-proof transmission. The illustrated

sequence of output signals—with U

lagging U

—applies to the direction of

motion shown in the dimension drawing.

The fault detection signal  indicates

fault conditions such as an interruption in

the supply lines, failure of the light source,

etc.

Signal period 360° elec.

Measuring step after

4-fold evaluation

The inverse signals , ,  are not shown.

The distance between two successive

edges of the incremental signals U

and

through 1-fold, 2-fold or 4-fold

evaluation is one measuring step.
