DCM armature supply unit master Signals are exchanged via a peer to peer interface The armature supply unit generates the current setpoint for the field supply unit and receives from the field supply unit the current actual value and fault signal Field weakening is possible Version 4 The same as version 3 however additionally with field reversal A 4Q unit should be used for the field supply unit in order to permit contactless changeover A warnine If the armature power unit is used to supply the field then it is absolutely necessary to provide overvoltage protection for the converter power semiconductors This is because if the input voltage is no longer present then the energy in the field circuit cannot be dissipated For version 4 with field reversal it is important to note that the overvoltage protection must be effective for both polarities In order not to unnecessarily load the overvoltage protection it should be ensured that when the pulses are inhibited the field current is already 0 for example this can be achieved by activating the standstill excitation as otherwise the remaining field energy must be dissipated through the overvoltage protection device Application SINAMICS DCM as field supply unit C98130 A7066 A501 03 7619 1 2012 3 Block diagrams 3 1 Version 1 Field supply with internal setpoint Field supply 1V1 1W1 3U1 3W1 O O O O O Current controller Switchover to f standstill
