More Information

Overview Manuals Field Bridge 15 A Wiring Lead Identification Offset Adjustment

Features:

  • Fits the 15 A SIMOREG DC-MASTER converter class.
  • Supplies a field circuit rated at 3 A DC.
  • Uses a two-pass primary-conductor arrangement with equal R1/R2 values.
C98043-A7010-L1 is the lower-current member of the A7010 field-supply pair and is selected by the converter’s 15 A armature rating.

Its equal sensing-resistor values and doubled primary path establish the L1 current-measurement arrangement.

Field input, controlled bridge, and DC field output are separated into clearly named connection points for tracing during integration.

The Siemens C98043-A7010-L1 Field Supply Power Section may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Supply, Switching, and Field Output

  • Input Pair: 3U1 and 3W1 supply the bridge.
  • Control Devices: V7 and V8 form the thyristor pair.
  • Output Pair: 3D and 3C connect to the DC field circuit.
  • Rated Field: The L1 bridge is rated at 3 A DC.

Two-Pass Measurement Path

  • Armature Class: The L1 arrangement belongs to 15 A converters.
  • Primary Path: The primary conductor is fed through twice.
  • R1: The R1 element is 0R1.
  • R2: The R2 element is also 0R1.

Gate and Cathode Marking

  • Gate Color: Gate leads are identified in yellow.
  • Cathode Color: Cathode leads are identified in red.
  • Lead Type: Betatherm 145 cable is specified for gating.
  • Lead Size: The stated cross-section is 1 mm².

Restoring Field-Current Zero

  • Trigger: Repeat the adjustment after the field board is replaced.
  • Parameter: Use P051 = 22 for the internal offset routine.
  • Purpose: The routine sets the zero point of field-current sensing.
  • Power State: Carry out physical replacement only with supplies isolated.
Description
For low-current SIMOREG DC-MASTER assemblies, Siemens C98043-A7010-L1 serves as the field-supply power section. The L1 configuration is tied to the 15 A armature-current class and supplies a field circuit rated at 3 A DC.

Siemens C98043-A7010-L1 places identical 0R1 values at R1 and R2 in the current-sensing network. In the 15 A connection layout, the primary conductor passes through twice, distinguishing the L1 current path from the single-pass 30 A arrangement.

At the bridge boundary, Siemens C98043-A7010-L1 accepts the field supply on 3U1 and 3W1 and presents the DC field connection on 3D and 3C. Thyristor positions V7 and V8 are driven through 1 mm² Betatherm 145 gate leads.

The maintenance procedure for Siemens C98043-A7010-L1 requires an isolated converter and ESD handling before board removal. After installation, P051 = 22 repeats the internal offset setting for the field-current measurement path.

Technical notes
Siemens C98043-A7010-L1 uses equal 0R1 values at R1 and R2 and a two-pass primary-conductor route for the 15 A class.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which ratings identify Siemens C98043-A7010-L1 rather than the L2 board?
Siemens C98043-A7010-L1 is specified for 15 A armature current and 3 A field current, with 0R1 used for both R1 and R2.
Why is the primary conductor routed twice for C98043-A7010-L1?
The official 15 A connection layout requires the C98043-A7010-L1 primary conductor to pass through twice; keep that routing when matching the original assembly.
Which terminals define the field circuit on C98043-A7010-L1?
C98043-A7010-L1 receives the field supply at 3U1/3W1 and connects the DC field side at 3D/3C.
How are gate and cathode leads identified around Siemens C98043-A7010-L1?
Around Siemens C98043-A7010-L1, gate leads are yellow and cathode leads are red; the gate-lead specification is Betatherm 145, 1 mm².
Can C98043-A7010-L1 be substituted for a 30 A L2 section?
Do not treat C98043-A7010-L1 as the 30 A version: its documented ratings and primary-conductor routing are different from L2.
Which parameter restores the field-current offset after changing C98043-A7010-L1?
Use P051 = 22 after changing C98043-A7010-L1 to repeat the internal offset adjustment.
