DC Drive Hardware Components

For SD3000 and SF3000 DC drives, the PMI is a four-slot rack containing the same
Power Supply module, PMI Processor module, and Resolver & Drive I/O module that
is used for Medium Power SA3000 AC drives. The hardware components that are
unique to a DPS DC drive system are the DC Power Technology module in the PMI
rack and the DC Power Modules. These are described in the following sections. See
figure 1.1.

2.3.1 Four-Slot PMI Rack and Modules

The PMI rack is designed to be mounted in the same cabinet or within 3.5 meters
(12 feet) of the DC Power Module. The PMI rack contains a Power Supply module, a
PMI Processor module, a Resolver and Drive I/O module, and a DC Power
Technology module as shown in figure 2.3.
