Sample wiring for vector drives

Drive line-up comprising three Motor Modules (chassis) with identical pulse frequencies or vector
(booksize)
Motor Modules (chassis) with identical pulse frequencies or vector (booksize) can be
connected to a DRIVE-CLiQ interface on the Control Unit.
In the following diagram, three Motor Modules are connected to interface X101.
Note
This topology does not match the topology created offline by STARTER and must be
changed.
Figure 12-25 Drive line-up (chassis) with identical pulse frequencies
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 ≤ 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.
