Drive line-up comprising four Motor Modules in the chassis format with different pulse frequencies
It is advantageous to connect Motor Modules with different pulse frequencies to different
DRIVE-CLiQ sockets of the Control Unit. They may also be connected at the same DRIVE-
CLiQ line.
In the following diagram, two Motor Modules (400 V, output ≤ 250 kW, pulse frequency
2 kHz) are connected to interface X101 and two Motor Modules (400 V, output > 250 kW,
pulse frequency 1.25 kHz) are connected to interface X102.
Note
This topology does not match the topology created offline by STARTER and must be
changed manually.
