Comprehensive descriptions of all

available interfaces as well as general

electrical information is included in the

Interfaces for HEIDENHAIN Encoders

brochure, ID 1078628-xx.

HEIDENHAIN encoders with  HTL

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 (does not apply to

HTLs). 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, for example a failure of the

light source.

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.
