3.2.2.1 Signal tracks
In case of HTL encoder interface the signals A+ and B+ are rectangular signals with a pha-
se-angle displacement by 90 degrees. The inverted signals will be generated internally and
does not need to be provided by the encoder. The pulse width and the phase diff erence
must be 2 µs at least.
