Chapter 2 - Start-Up Instructions
IV A 2 - 22 DCS 500B / DCP 500B Operating Instructions
2.9 Presetting the 3-phase field supply unit DCF 50xB
This is a new functionality available for the first time with software version S21.232.
When commissioning a drive consisting of a DCS converter for the armature supply
and a DCF converter for the field please try to make sure both converters will be
equipped with at least this software version.
Make sure that existing supply voltages for power section, field supply unit (field ex-
citer) and field winding, fan, etc. match the rated data of the components used.
402 = 11303
field current reference received from the DCS 500B via FEX-link connected to cur-
rent controller
405 = 1 Panel display: CURR_REF
input P402 via CURR_REF activated
409 = 0
current controller without feedforward function
420 = 2 or 3 Panel display: METHOD 2 ALARM or METHOD 2 FAULT
current ripple monitoring based on method 2; in case a current bubble is missing an
alarm or fault is generated
421 = 25.0
threshold for current ripple monitoring = 25%
501 = Rated motor voltage
keep it to default; if set to lower values adapt the current controller to avoid over
voltage faults
502 = Rated motor current
set this parameter to the motor´s nominal field current
507 = Rated line voltage
Used to scale parameters referring to the line voltage, such as line undervoltage.
901 = 10916
902 = 10916
no need for an external start command for the field converter; when the start command
is given to the DCS 500B feeding the armature, this converter automatically starts and
controls the DCF 500B
906 = 12502
emergency stop command disabled
907 = 10917
no need for an external reset command for the field converter; when an error occurred
either in the field or the armature converter the fault can be reset by the reset command
connected and given to the DCS 500B; it is internally transferred to the DCF 500B
911 = 10908
input motor fan acknowledge deactivated
1215 = 4 Panel display: FEXLINK NODE 1
DCF field mode, DCF 506 is monitored, FEX-link in use and DCF 500B is node 1
1216 = 10703
digital input 2 used to monitor the motor fan at a DCS 500B is now used to monitor
the DCF 506 overvoltage protection
1217 = 0 or 1 Panel display: OVP ALARM or OVP ALARM
