Simple mounting, compact dimensions and high signal quality together with a large number of signal periods: these are the outstanding characteristics of the new generation of modular angle encoders in the Heidenhain ERA 4000 series.
This new range of encoders is ideally suited to use in highly dynamic applications where measurement within a few angular seconds is a pre-requisite.
Due to the fact that a control loop for position and velocity requires a position encoder, the position information has significant influence on performance, particularly on the performance of direct drives. Therefore, the quality of the position information directly affects positioning accuracy and rotational speed stability. As a result, in metalcutting applications, position error within the signal period of the velocity loop can lead to wave-shaped dimensional inaccuracy of the workpiece surface. Position error also aggravates noise and heat generation in the motor. This latest development from Heidenhain, with its high signal quality and large number of signal periods, eliminates these problems, making it ideal for the requirements demanded by direct drive technology.
