ABB DCS 500B

DCS500 Pin and Parameter list
A 38
DCF MODE
Parameter of DCF_FIELDMODE-function block (S2/16 | S21.232)
Selects the control configuration for the DCF mode used for high inductive loads:
0 = DISABLE
1 = DCF CURR CONTROL Current controller adapted for high inductive load
2 = STAND ALONE functionality of (1) plus monitoring of overvoltage
protection DCF 506
3 = Reserved
4 = FEXLINK NODE 1 functionality of (2) plus reading of references /
commands via X16 as first field exciter
5 = FEXLINK NODE 2 functionality of (2) plus reading of references /
commands via X16 as second field exciter
6 = MG-SET functionality of (2) plus transfer of references /
commands via X16 to other field exciter(s)

DI/OVP
Input of DCF_FIELDMODE-function block (S2/16 | S21.232)
Based on the wiring diagram example the relay contact of the overvoltage protection DCF
506 is connected to the digital input 2 of the SDCS-CON-2 board. By default this hardware
input is connected to the input of the DCF fieldmode block. In case a different hardware
input is used, adapt the interconnection!

OVP_SELECT
Parameter of DCF_FIELDMODE-function block (S2/16 | S21.232)
If the overvoltage protection unit DCF 506 has triggered because of an overvoltage
condition the reaction of the converter can be selected by this parameter:
0 = OVP ALARM indication and blocking of current controller; controller is
released, when trigger signal goes back to logic “0” level
1 = OVP FAULT indication, forcing the current to zero and switch off
