Overview of Drive 1-15
7000 “C” Frame - Marine 7000L-UM302B-EN-P – June 2013
Control Hardware
The control hardware includes a processor board (DPM) with an
interface to six fiber optic boards (depending on the voltage and
number of switching devices) via OIBB, an analog conditioning
board (ACB) and an external IO board (XIO). The control hardware
is used for rectifier and inverter, induction or synchronous drive
control and the two rectifier types (18-pulse or Active Front End).
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.
