Absolute Ring Encoder Delivers Accurate Angular Motion Feedback

Sporting design features that enable it for use in angular motion feedback, the ECA 4000 absolute ring encoder features absolute technology and provides a direct upgrade path for the company’s ERA 4000. The mechanically-compatible ECA 4000 series comes in outer diameters ranging from 104 mm to 560 mm. Each ring employs a three-point centering method, which allows the installer to locate the center of the drum to the center of the machine bearing quickly. Then a shim or separately ordered plastic mounting tool is used between the reader head and drum to make the appropriate scanning gap, a quick check with the PWM 20, PWT 100 or other HEIDENHAIN diagnostic tool to verify signal quality, and the whole encoder system is ready for feedback to the control, via the high speed serial interface Endat 2.2.
