Up to 4 measuring functions can be simultneously active; the measured value
memory is read out using a handshaking technique according to [4720], [4730].
Index [n-1] --> encoder n (n = 1, 2)
Index [0] --> encoder 1
Index [1] --> encoder 2
<3> All other bits of the encoder control word must be 0.
NOTE: SINAMICS S110 supports only one encoder. This encoder may be parameterized as encoder 1 or encoder 2.
