Description

The QUAD 1024 1ki /1024 is a high performance quasi-absolute optical encoder mounted on a motor assembly. They offer high resolution up to 4,096,000 counts per rotation with a maximum accuracy error of +/- 0.005 mechanical degrees within one 360 degree rotation. The analog sine/cosine signals (A,B) from the incremental encoder is signal-conditioned and interpolated by a factor of 1000x by the built-in hardware interpolator chip. The signal conditioning incorporates online, real time algorithm that features automatic signal gain and offset correction, as well as, factor based phase correction.
