This group of parameters selects encoder 1 type, pulses per revolution, etc, division coefficient, etc.
The Position angle is from reading in self-learning, unable to be set. The filtering time shall be
adjusted within a controllable range. P22.06 or hardware line changing shall be selected for encoder
according to actual situation.
P22.01 setting encoder type, 0: Incremental encoder; 1: SinCos encoder; 2: Spare; 3: Rezav encoder.
P22.02 setting the encoder pulse count.
