TTL square-wave signals

HEIDENHAIN encoders with TTL  interface incorporate electronics that  digitize sinusoidal scanning signals withnor without interpolation.

The incremental signals are transmitted as the square-wave pulse trains Ua1 and Ua2, phase-shifted by 90° elec. The reference mark signal consists of one or more reference pulses Ua0, which are gated with the incremental signals. In addition, the integrated electronics produce their inverted signals Ua1(Inverted) and Ua2(Inverted) and Ua0(Inverted)  for noise-proof transmission. The illustrated sequence of output signals—with Ua2 lagging Ua1—applies to the direction of motion shown in the dimension drawing.

 The fault-detection signal UaS(Inverted)  indicates fault conditions such as breakage of the power line or failure of the light source. It can be used for such purposes as machine shut-off during automated production. The distance between two successive edges of the incremental signals Ua1 and Ua2 through 1-fold, 2-fold or 4-foldevaluation is one measuring step. The subsequent electronics must be designed to detect each edge of the square-wave pulse. The minimum edge separation a stated in the Specifications applies for the specified input circuit with a cable length of 1 m and refers to a measurement at the output of the differential line receiver.

 Note; Not all encoders output a reference mark signal, fault-detection signal, or their inverted signals. Please see the connector layout for this.
