4.7.4 Arranging the Inverter Modules

Arrangement with
the ZKF 120
Voltage protection
module
4 – 34
The following connection overview illustrates the combination of different
types of drives in an inverter system. The arrangement of the inverter modules
also depends on the combination used.
The following guidelines should be observed:
The inverter modules for the most powerful motors (e.g. spindle, axis 1, axis
2, etc.) must be placed next to the right of the power supply module.
If you want to connect motors requiring a dc-link filter (linear motors, torque
motors, special synchronous spindle motors), first of all ensure that the ZKF
dc-link filter's maximum permissible load is not exceeded. The dc-link filter
is inserted next to the left of the inverters in the dc-link and connected.
Depending on the application, there are the following possibilities:
In this application, a ZKF 120 was inserted after the high-performance
modules for the spindles in order to connect two direct drives.
