Rockwell Automation 7000A PowerFlex Medium Voltage AC Drive - Air-Cooled (A Frame) - Manual (Page 28)

1-12 Overview of Drive
7000A-RM001A-EN-P – January 2011 7000 “A” Frame
Control Hardware The control hardware includes a Drive Processor Module (DPM)
with an interface to six Optical Interface Boards (OIB) (depending
on the voltage and number of switching devices) via the Optical
Interface Base Board (OIBB), an Analog Control Board (ACB) and
an external IO board (XIO). The control hardware is used for
rectifier and inverter, induction or synchronous drive control and all
configurations.
The DPM features two floating point DSPs (Digital Signal
Processor) and a FPGA (Field Programmable Gate Array) for
advanced functions such as gating and diagnostics, fault handling
and drive synchronization control.
