Figure 1.4 Active Converter Operating as a Coupled Unit (DPI SLAVE)
Stand Alone
Figure 1.5
shows the Active Converter wired to operate as a Stand Alone
unit (DPI MASTER). In this configuration, the Converter may have a HIM
or any PowerFlex 7-Class network communication adapter (20-COMM-x)
connected. This may be preferred when the converter is to supply the DC
bus for a set of common bus inverters. When configured for "Run On Start,"
the precharge bypass contactor may be configured to close when the power
is turned on and the DC Bus voltage is stable (see Parameter 51 - [Option
Select]). The Converter starts and stops with commands from the HIM, the
1203-USB or 1203-SSS serial converter, or a 20-COMM-x network
communication adapter.
