Preparation for commissioning
2.6 Supported sample topologies
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
The offline topology automatically generated in the STARTER commissioning tool must be
manually modified, if this topology was wired.
