Control Hardware
The control hardware (Series B) 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 two rectifier types (18 Pulse or
PWM 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.
