ParCh Parameters can be read or written via "ParCh", see chapter
"3.3.4.3 Parameter channel".
dmControl The word "dmControl" is used to set the operating state and the oper-
ating mode.
See chapters "6.1.2 Changing the operating state" and
"6.2.2 Starting and changing an operating mode" for a detailed
description of the bits.
RefA32, RefB32 The two double words "RefA32" and "RefB32" are used to set two val-
ues for the operating mode. The meaning depends on the operating
mode; it is described in the chapters on the individual operating
modes.
Ramp_v_acc / Ramp_v_dec The double words "Ramp_v_acc" and "Ramp_v_dec" are used to set
the acceleration and the deceleration. They correspond to the param-
eters of the same name. See the product manual for a description.
EthOptMapOut1 ... EthOptMap-
Out3
The double words EthOptMapOut1 ... EthOptMapOut3 contain select-
able parameters, see chapter
"5.7.3 Setting the mapping for I/O scanning".
