励磁机)或

DCF504A-0050或三相励磁机)8.4.7 Field exciter configurations
The data exchange between the SDCS-CON-x and
the field exciter SDCS-FEX-2 or the DCF503A/
504A-0050 is done via a RS485 serial link, which
can be configured as a bus structure. This link is
used to transfer references, actual values and settings for up to two field exciter units.
The drive software located on the SDCS-CON-x
board consists of two field supply functions, first
field exciter and second field exciter. The first field
exciter is already connected to the EMF controller
to control the motor in all points of the motor diagram. The second field exciter is accessible via the
field current reference.
The RS485 interface works with a screened twowire cable. The allowed length is 5 m. The wires
have to be connected to the terminals X2:1 and
X2:2 and the screen to X2:3.
Typical application of this kind is two DC motors
connected to one converter. The load sharing can
be done by means of adjusting the excitation current of the second DC-motor.
There are two possible configurations for two Node
numbers of the field exciters:
- one SDCS-FEX-2 and one external field exciter
(DCF503A-0050, DCF504A-0050 or 3-phase
field exciter) or
- two external field exciter units (DCF503A-0050,
DCF504A-0050 or 3-phase field exciter)If a DCF503A-0050 is in use two diode-thyristor
modules are arranged as a half-controlled singlephase rectifier. If a DCS504A-0050 is in use four
thyristor-thyristor modules are arranged as a fullcontrolled single-phase rectifier. The anodes of the
two diodes (anodes / cathodes of the thyristors) are
not connected directly to each other as usual; they
are connected to the ends of the primary winding of
the current transformer. The centre tap is the negative output of the rectifier. Thus it is possible to
measure the DC current with an AC current transformer.
A MOV (Metal Oxide Varistor) protects the AC input
against voltage spikes from the external source.
Another MOV protects the DC output against voltage surges which can be caused by the field winding of a DC machine. The free wheeling function
needed e.g. during network failure is ”build in” because of the diodes, if the half-controlled version is
in use. If the full-controlled version is used the free
wheeling function is realized by using the thyristors
in diode mode, triggered by a fast voltage rise.The setting and updating of all control parameters
are set from armature converter via RS485 interface. Actual current, field current reference, control
and status bit are cyclic sent via RS
