Remark
p0130
4
Configure four MDS.
p0180 4 Configure four DDS.
p0186[0...3]
0, 1, 2, 3
The MDS are assigned to the DDS.
p0820, p0821 Digital inputs DDS
selection
The digital inputs for motor changeover via DDS selec-
tion are selected. Binary coding is used (p0820 = bit 0,
etc.).
p0822 to p0824
0
p0826[0...3]
0, 1, 2, 3
Different numbers indicate a different thermal model.
p0827[0...3] 0, 1, 2, 3 Assigning the bit from r0830 to the MDS. If p0827[0] =
1, for example, bit p0830.1 is set when MDS0 is se-
lected via DDS0.
r0830.0 to r0830.3 Digital outputs, contac-
tors
The digital outputs for the 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.
p0833.0..2 0, 0, 0 The drive controls the contactor circuit and pulse inhi-
bition. Parking bit (Gn_ZSW14) is set.
Procedure for changeover between motor data sets
1. Start condition:
For synchronous motors, the actual speed must be lower than the speed at the start of
field weakening. This prevents the regenerative voltage from exceeding the terminal
voltage.
2. Pulse inhibit:
The pulses are inhibited after a new drive data set is selected with p0820 to p0824.
