Multiple-tier configuration
Figure 8-6
Note
When the power supply input is on the right-hand side of the drive line-up (e.g. in a multiple-
tier configuration), the above rules apply in reverse.
This means that: The Motor Modules are arranged in order of power from the highest power
to the lowest power followed by the DC link components, such as the Braking Module.
