The MDS are assigned to the DDS.
The digital inputs for motor switchover via DDS
selection are selected. Binary coding is used
(p0820 = bit 0 etc.).
Different numbers indicate a different thermal model
The bits of p0830 are assigned to the MDS. If
p0827[0] = 1, for example, bit p0830.1 is set when
MDS0 is selected via DDS0.
The digital outputs for the auxiliary contactors are
assigned to the bits.
The digital inputs for the feedback signal of the motor
contactors are assigned.
