Rules for wiring with DRIVE-CLiQ
Drive line-up comprising four Motor Modules (chassis) with different pulse frequencies
Motor Modules with different pulse frequencies must be connected to different
DRIVE-CLiQ interfaces on the Control Unit.
In the following diagram, two Motor Modules (400 V; output v 250 kW; pulse fre-
quency 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 (see Subsection 2.3.4.)
