Overview of typical encoders
The following overview lists the parameters of the HEIDENHAIN encoders that are
typically connected to the product.
When connecting other encoders, refer to the encoder's
documentation for the required parameters.
Linear encoders
Examples of incremental encoders that are typically used
Encoder series
LS 388C/688C
LS 187/487C
LB 382C
Examples of absolute encoders that are typically used
Encoder series
LC 415
Angle encoders and rotary encoders
Encoder series
RON 285C
ROD 280C
ROD 480
ERN 180
ERN 480
The formulae below enable you to calculate the nominal increment of
the distance-coded reference marks with angle encoders:
Nominal increment = 360°  number of reference marks × 2
Nominal increment = (360° × nominal increment in signal periods)  line
