4.4.6.4 Encoder correction
Offset- and amplitude error corrections must be done at all analog encoders. However,
the static encoder error corrections at the sine incremental, the SinCos Hiperface, the
SinCos Endat 2.1 and the SSI encoders are advisable upon completion of first correction.
1. Offset and amplitude error correction
Amplitude and offset of the sinusoidal and cosine tracks are measured here. This way is
optimized, that the unit circle of the sine value and the cosine value is centered and has
a 90% amplitude. On the ProDrive page Encoder diagnosis the measured values can be
included for checking. If the measured points are on the predefined green circle, the angle
and speed measuring have been processed correctly.
