Remark
Configure 4 MDS.
Configure 4 DDS.
The MDS are assigned to the DDS.
The digital inputs for motor changeover via DDS
selection are selected. Binary coding is used (p0820 =
bit 0 etc.).
Different numbers indicate a different thermal model
Assign the bit from p0830 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.
The drive controls the contactor circuit and pulse
inhibition. Parking bit (Gn_ZSW14) is set.
