Control system block diagram
The BCU is the major component of the drive control system and performs general drive,
motor control, and closed loop functions.
The main internal control devices and the peripheral input and output interfaces to the
customer communicate with the BCU via optical fibers and hardwired I/Os.
The control hub provides the interfaces between the inverter unit and the control
compartment. This includes the inverter control as well as the monitoring signals from the
inverter cabinet.
DDCS communication channels are used for high speed data transfer via the control hub
to the PEBB control boards inside the power modules.
Internal and external, analog and binary I/O signals are connected to the BCU via an
AC500 I/O controller. The I/O controller and the BCU communicate via a fieldbus link.
Analog measurement signals (i.e. supply and motor voltages and currents) are transmitted
to the BCU via the CVMI2 board.
For the physical locations of the control components see chapter
