Hardware description
The BCU-01/11 are control units used for controlling converters via fiber optic links.
It contains integrated branching unit functionality for collecting and storing real-
time data from the converter modules to help fault tracing and analysis. The data is
stored in a secure data card.
The control unit types have a different number of fiber optic connections:
The control unit requires an external 24 V DC power source. It has two option slots
for encoders and fieldbus adapters and a removable memory unit. For example, if
the control unit needs to be replaced, the parameter settings can be retained by
transferring the memory unit from the defective control unit to the new one.
The control unit has an on-board data logger that collects real-time data from the
converter power stages to help fault tracing and analysis. The data is stored onto
