Redundant system configuration is controlled from the converter’s front panel
configuration menu. Each online unit is assigned a redundancy configuration address.
This address is dependent on the location of the online converter with reference to the
backup. The unit closest to the backup must be converter # 1. The next unit down must
be converter # 2. Figure 28 shows the appropriate entries for a 1:3 system

Configure the online units first, and then configure the backup unit. Redundant polling
starts when the backup is configured. If this polling starts before the online units are
configured, a high-speed bus fault will result. This fault should clear when configuration
is completed. At this point, control of the redundant system is performed from the backup
converter.
