Features:
- Controls the field power stage in 2Q and 4Q SINAMICS DCM converters.
- Isolates field firing commands through dedicated pulse transformers.
- Returns measured field current through a shunt-based evaluation path.
The board occupies the field-converter branch rather than the armature control path.
Its input and output terminals keep incoming field power distinct from the controlled connection to the motor field.
An independent field-voltage measurement supplies the timing reference used for gating synchronization.

Infeed and Controlled Output
- Incoming field power: The supply connects at 3U1 and 3W1.
- Load-side path: Controlled field output is provided at 3C and 3D.
- Converter scope: The same board arrangement covers 2Q and 4Q converters.
- Functional boundary: Field-current control remains separate from the armature channel.
Gate-Pulse Transfer
- Pulse generation: The board develops firing commands for the field power stage.
- Galvanic separation: Pulse transformers isolate the firing path.
- Voltage acquisition: Field-supply line voltage is measured through an isolated circuit.
- Timing reference: The isolated voltage signal establishes the field gating phase.
Field Actual-Value Circuit
- Sensing element: Shunt resistors measure current in the field path.
- Evaluation stage: Dedicated circuitry converts the shunt signal into the actual value.
- Control return: The measured value is supplied to the field-current regulator.
- Channel separation: Field feedback is evaluated independently of armature-current measurement.
Independent Field Phasing
- Sync source: Gating timing is derived from the field-supply infeed.
- Phase freedom: The field infeed phase angle may be selected independently.
- Armature relation: No fixed phase relationship to the armature infeed is required.
- Electronics relation: The electronics supply does not define the field gating phase.
