HIEE300697R1 Controller DC

HIEE300697R1 Controller DC

The control system requires inputs signals in order to carry out control, supervision and protection of the drive. The output signals are triggering pulses to thyristors, excitation reference current and digital outputs for control and supervision. The processor (PPC322 AE) where the control program is running, communicates with its analogue/digital input/output cards (UAC326), digital input/output cards (UDA327) pulse generation card (GDB021) and serial communications with the plant control system (PMA324) through a 16-bit parallel communication bus B448.

For command and supervision of the equipment there are local and in-field control panels with direct communication with the processor through the ARCNet network. This network also serves for control and supervision of the cooling system for the power part components (thyristors, resistors).

Part of the hardware is also represented by the PSR input signal modulation cards, the UGA 359 motor current cards, UUA 358 voltage reference adapting card, current-voltage signal converter for the motor air gap supervision and cycloconverter output voltage measuring LEM sensors.

The thyristor supervision cards in the power part provide an optical signal to the XV C513 receiver cards and through the XV C512 control card, they provide a PSR controller condition signal through digital inputs. Also, there are analogue signal supervision cards (CSA 463 motor over current supervision) and digital signals (supervision of backplane cards B448, CSA 465), DDA 353 cycloconverter bridge control and pulse amplifying cards LT8951.
