Preparation for commissioning
1.5 Rules for wiring with DRIVE-CLiQ
Drive line-up comprising four Motor Modules in chassis format with different pulse frequencies
Motor Modules with different pulse frequencies must be connected to different DRIVE-CLiQ
sockets on the Control Unit.
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.
