Industrial drive controls require fast and precise feedback of the servo motor rotor angle to achieve best possible load balancing. This is where high-resolution optical encoders come in. By scanning multiple Vernier tracks, angle resolution can be pushed into outstanding ranges. Latest EncoderBlue devices also benefit from near-UV LED illumination, which improves signal clarity for optimal interpolation performance. The next-generation sensors now available generate high-quality analog sin/cos signals with 2,048 cycles per revolution for latency-free feedback and rigid torque control. Thanks to the sector detectors of the new iC-PNE, Vernier calculation efforts are reduced, making it easier to build such high-end encoder systems.
