Sine Cosine/Serial 842HR • Absolute feedback for position control • High resolution incremental feedback for speed control • Sine/Cosine differential interface • Digital bi-directional RS-485 interface • Compatible with Hiperface interface • Internal diagnostic functions • Replace Multiple Encoders with a Single 842HR Encoder • Today’s high performance digital servo drive systems require absolute feedback for position control and high resolution incremental feedback for speed control. • Conventional systems use multiple incremental and absolute encoders to achieve this. • The Allen-Bradley® 842HR Sine/Cosine encoder combines the advantages of incremental and absolute encoder technologies in a single, standalone unit targeted for high performance digital servo drive systems. • Ideal Applications: Compatible with a variety of motor control products including Kinetix drives and the Allen-Bradley Guardmaster® MSR57 safe speed monitoring relay, the 842HR is a flexible solution for wide range of industrial applications. • Single- Versus Multi-turn: In a single-turn encoder, absolute position retention on one full rotation of the encoder is provided. Multi-turn encoders provide absolute position on multiple turns of the encoder shaft (better for linear applications).
