Power Section Field To 600a 6RY1703-0CA01 6RY1 703-0CA01 6RY17O3-OCAO1

Siemens 6RY1703-0CA01 Field Supply Board

The Siemens 6RY1703-0CA01 is a field supply board / field power section used in the SIMOREG DC Master platform.

Siemens’ own portal identifies it as “power section field to 600A”, while Siemens application material for the 6RA70 series explains that these drives are used for the armature and field supply of DC motors and support several field-supply operating modes, including autonomous field supply, external field current setpoint control, and operation as a field slave with an armature supply master.

Trade catalog data for the same part lists 6RY17030CA01 as the catalog number, ties it to the SIMOREG DC Master Base Drive Panel, and gives a working range of 140 to 510 A at 460 V.

Siemens fault-diagnostics material for 6RA70 devices also explains that the field module consists of C98043-A7014 + C98043-A7015, and that A7014 handles field-supply firing pulses together with shunt-based field-current sensing.

Product Data

Application Scenarios

6RY1703-0CA01 is used in DC motor field-supply applications built around SIMOREG 6RA70 drives.

Siemens documents four practical field-supply arrangements for this platform: internal fixed field current, external analog field current setpoint, field supply linked to an armature supply unit via peer-to-peer interface, and field reversal. That makes this board relevant in DC drive systems where stable field current control is part of the drive architecture rather than an external add-on function.

Why Choose This Product

This board is a strong match when the installed DC drive already uses the SIMOREG field-supply section and the repair needs to remain aligned with the original 6RA70 hardware path.

Its value is not just that it is a Siemens spare PCB, but that it belongs to the field power section of the drive, which directly affects field-current generation, synchronization, and related field-side measurement functions.

FAQ

Q1. What type of board is 6RY1703-0CA01?
6RY1703-0CA01 is a field supply board for the SIMOREG DC Master platform. Siemens describes it as a power section field to 600A.

Q2. What does this board do in the system?
Its role is to handle the field supply section of the DC drive. Siemens application material for the 6RA70 explains that the drive platform is used for the armature and field supply of DC motors and supports multiple field-control operating modes.

Q3. What should be checked when selecting 6RY1703-0CA01?
Confirm the exact order number, the SIMOREG / 6RA70 platform, and the installed field-supply configuration. If the drive is part of a base-drive panel setup, the matching SIMOREG panel family should also be checked.

Q4. How should the key specification be understood?
The most useful identifiers are field power section, up to 600 A, and the matching SIMOREG DC Master platform.

A catalog entry also lists 140 to 510 A at 460 V, which is a practical panel-selection reference for this part.

Q5. How should faults be diagnosed before replacing this board?
For 6RA70 field-side diagnosis, Siemens notes that field-current behavior can be checked through parameters such as r034, r035, and r036, and that the field module handles field firing pulses and field-current sensing.

Siemens also states that after replacing field modules such as A7014+A7015, an offset adjustment with P051 = 22 is required.

That makes it important to confirm a genuine field-module fault before replacement and to complete the required adjustment afterward.
