Parameter Settings Remark
p0130 4 Configure 4 MDS
p0180 4 Configure 4 DDS
p0186[0..3] 0, 1, 2, 3 The MDS are assigned to the DDS.
p0820, p0821 Digital inputs DDS
selection
p0822 to p0824 0
The digital inputs for motor switchover via DDS
selection are selected. Binary coding is used
(p0820 = bit 0 etc.).
p0826[0..3] 1, 2, 3, 4 Different numbers indicate a different thermal model
p0827[0..3] 1, 2, 3, 4 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.
p0830.1 to
p0830.4
Digital outputs, auxiliary
contactors
The digital outputs for the auxiliary contactors are
assigned to the bits.
p0831[0..3] Digital inputs, auxiliary
contacts
The digital inputs for the feedback signal of the motor
contactors are assigned.
