Control Hardware
The control hardware includes identical drive control boards for
machine and line side complete with up to three fiber optic interface
boards (depending on the voltage and number of switching devices),
signal conditioning boards for machine and line side, customer
interface board and external I/O board. The common drive control
boards are used for the rectifier and inverter, induction or synchronous
drive control, and the three rectifier types (6-pulse, 18-pulse, or
Active Rectifier).
The drive control boards feature a floating point digital signal
processor and field programmable gate arrays for advanced functions
such as gating and diagnostics, fault handling, and drive
synchronization control.
