HW of the closed-loop thyristor current control D02_TCCONTR
The software for the standard closed-loop thyristor current control
comprises the set from the converter-specific function blocks (FB).
The FBs are programmed in a standard function chart (CFC) for normal
applications of a DC drive.
The closed-loop current control should be integrated in the plant/system
software. Generally, there is a higher-level closed-loop and open-loop
speed control.
