Drive configuration with reduced components
Converters D1...D4 (400...500 V) using ’on board’ field exciters
Converters D5 using FEX-425-Int field exciter, but externally supplied
Wiring the drive according to this diagram gives the same control performance, but a lower degree of
flexibility. Dynamic Braking keeps the main contactor K1 in state ON during braking.
Selection of components: The wiring diagram is valid for a DCS800 converter construction type D1...D4 ≤ 525 V and D5
≤ 500 V. The ’on board’ field exciter (D1...D4) can be used at line voltages up to 525 V and will give field currents up to 6 /
15 / 20 / 25 A. For higher field currents, use the next larger field supply units DCF803/804 or a 3-phase field supply DCS800.
* D1-D4: On board field exciter (PIN-4)
D5: FEX-425-Int field exciter, supplied external
