Interfaces of HEIDENHAIN Encoders March 2015 Interfaces As well-defined transitions between Note encoders and subsequent electronics, Specialized encoders can have other interfaces ensure the reliable exchange interface properties, such as regarding of information. the shielding. HEIDENHAIN offers encoders with interfaces for many common subsequent electronics. The interface possible in each respective case depends, among other things, on the measuring method used by the encoder. With the absolute measuring method Interface electronics Measurement procedure the absolute position information is gained Interface electronics from HEIDENHAIN In the incremental measuring method directly from the graduation of the adapt the encoder signals to the interface the position information is obtained by measuring standard. The position value is of the subsequent electronics. They are counting the individual increments available from the encoder immediately used when the subsequent electronics (measuring steps) from some point of upon switch-on and can be called at any cannot directly process the output signals origin. Since an absolute reference is time by the subsequent electronics. from HEIDENHAIN encoders, or if necessary in order to determine the additional interpolation of the signals is positions, a reference-mark signal is output Encoders that operate with the absolute necessary. as well. As a general rule, encoders that measuring method output position operate with the incremental measuring values. Some interfaces provide Yo
