<1> The measured value memory is read out using a handshaking technique according to [4720], [4730].
<2> Index [n-1] --> encoder n (n = 1, 2, 3)
Index [0] --> encoder 1
Index [1] --> encoder 2
NOTE: SINAMICS S110 supports only one encoder. This encoder may be parameterized
as encoder 1 or encoder 2.
<3> All other bits in the encoder control word must be 0.
<4> Increasing position actual values (r0482) --> The 0/1 edge is evaluated.
Decreasing position actual values (r0482) --> The 1/0 edge is evaluated.
This means that the same reference point is always used when traversing to an equivalent zero mark.
