Example application
Figure 4-12 Configuration 2 with six Unidrive SPM power modules
4.7.3 Configuration 3
This configuration allows the user to operate, either with both modules or with one
individual module (when low current required / a module is faulty) thereby providing
redundancy. In the event of power module failure, this configuration allows operation to
be continued with the healthy / OK module at lower current profile.
A block diagram for configuration 3 is shown in Figure 4-13. The items shown in Figure
4-13 may be required for this configuration.
