Overview Manuals Field Circuit Converter Wiring Quadrant Layout Replacement Checks

Features:

  • Supports the 30 A SIMOREG DC-MASTER converter class.
  • Provides a 5 A rated DC field-current path.
  • Connects the field bridge through 3U1/3W1 and 3D/3C terminals.
C98043-A7010-L2 separates the field-supply function from the converter control electronics while remaining part of the low-current power section.

The L2 coding defines the 30 A armature class, 5 A field rating, and the lower R2 resistance used by this arrangement.

Both single-quadrant and four-quadrant connection drawings place the module in the field and power-section wiring path.

The Siemens C98043-A7010-L2 Field Supply Power Section may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Bridge Components and Sensing

  • Bridge Devices: V7 and V8 form the controlled field bridge.
  • Sensing Network: R1 is 0R1 and R2 is 0R05.
  • Field Rating: The DC field-current rating is 5 A.
  • Gate Leads: Betatherm 145 conductors are specified at 1 mm².

From AC Supply to DC Field

  • AC Entry: Field supply enters through 3U1 and 3W1.
  • DC Exit: Field output is presented at 3D and 3C.
  • Connector Set: XF1 and XF2 group the field-bridge connections.
  • Current Class: The L2 path is assigned to 30 A converters.

Operating-Quadrant Context

  • 1Q Drawing: The module appears in the 30 A single-quadrant connection plan.
  • 4Q Drawing: The same field section is shown for 15–30 A four-quadrant converters.
  • Primary Route: The L2 primary conductor is fed through once.
  • Power Context: Armature and field paths remain separately identified in the converter wiring.

Safe Board Change Sequence

  • Isolation: Remove power before the PCB is inserted or removed.
  • Personnel: Replacement is restricted to qualified personnel.
  • ESD: Discharge static electricity before touching the board.
  • Offset: Run P051 = 22 after replacement to reset the field-current zero point.
Description
Siemens C98043-A7010-L2 is the field-supply power section used in 30 A SIMOREG DC-MASTER converter assemblies. It carries the controlled field-current path within the drive power section and is rated for 5 A DC field current.

The field bridge on Siemens C98043-A7010-L2 is built around thyristor positions V7 and V8. Input points 3U1 and 3W1 feed the bridge, while 3D and 3C form the DC field-side terminals after the switching network.

For current handling, Siemens C98043-A7010-L2 uses an R1 value of 0R1 and an R2 value of 0R05. The L2 arrangement serves the 30 A armature-current class with its primary conductor passed once in the connection diagrams.

When Siemens C98043-A7010-L2 is replaced, power must be removed before the PCB is handled and the internal offset adjustment is repeated with P051 = 22. The adjustment re-establishes the zero point of the field-current sensing path.

Technical notes
Siemens C98043-A7010-L2 uses 3U1/3W1 field inputs, 3D/3C field outputs, and 0R1/0R05 sensing resistors.
