More Information

Overview Manuals Control Core Interfaces Software Match Supply Limits

Features:

  • Implements SIMOREG converter regulation through CUD1 L2 processor electronics.
  • Combines serial, analog, and binary control paths on one board.
  • Includes the terminal set supplied with the C98043-A7001-L2 assembly.
The CUD1 architecture brings command processing and signal conversion together inside the converter control layer.

Its L2 hardware designation separates this board from the earlier control-electronics release associated with pre-3.0 software.

Terminal-level interfaces expose operating signals without moving the regulation algorithms away from the central processor electronics.

The Siemens 6RY1703-0AA01 SIMOREG DC-MASTER CUD1 Control Electronics may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
Siemens 6RY1703-0AA01 SIMOREG DC-MASTER CUD1 Control Electronics Manuals, Datasheets, Links Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

CUD1 Regulation Core

  • Board identity: The control electronics use internal part C98043-A7001-L2.
  • Processor duty: CUD1 executes both open-loop and closed-loop converter control.
  • Hardware generation: The L2 assembly is assigned to software release 3.0 and higher.
  • Signal conversion: On-board ADC and DAC circuits link the processor with analog channels.

Terminal and Serial Paths

  • G-SST1: The first serial connection is available at X300 through the PMU.
  • G-SST2: The second serial path is routed to terminals 56 through 60.
  • Analog outputs: DAC channels appear at terminals 14 and 16.
  • Current signal: Terminal 12 delivers 5 V when rated current is reached.

L2 Release Boundary

  • Release threshold: C98043-A7001-L2 is used with software version 3.0 or later.
  • Earlier hardware: C98043-A7001-L1 belongs to software below release 3.0.
  • Matching rule: The complete L-number is required when identifying the correct CUD1 electronics.
  • Stored parameters: Converter parameters reside in the backplane EEPROM rather than the CUD1 board.

Auxiliary Output Limits

  • Encoder feed: P15 provides encoder power with a 200 mA limit.
  • Binary-input feed: P24 is an output and must not be externally energized.
  • Digital outputs: Terminals 46 and 48 provide 24 V outputs rated at 100 mA.
  • Reference scheme: The analog and binary interfaces operate with ground-referenced signals.
Description
At the center of SIMOREG DC-MASTER regulation, Siemens 6RY1703-0AA01 provides CUD1 control electronics identified as C98043-A7001-L2. The processor board performs open-loop and closed-loop control and is supplied with its terminal connections.

Software compatibility distinguishes 6RY1703-0AA01 from the earlier L1 hardware. The L2 electronics are assigned to software release 3.0 and higher, so the complete internal part number must be matched when the control hardware is identified.

Field and command signals reach Siemens 6RY1703-0AA01 through ground-referenced analog and binary I/O. G-SST1 is available at X300 through the PMU path, G-SST2 is routed to terminals 56–60, and the analog channels include inputs 4/5 and 6/7 plus DAC outputs at terminals 14 and 16.

Auxiliary supplies on 6RY1703-0AA01 have defined boundaries: P15 provides up to 200 mA for encoder power, while the P24 point belongs to the binary-input supply and must not receive an external feed. Two 24 V binary outputs are available at terminals 46 and 48 with 100 mA capacity.

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.
Why must the L-number be checked when identifying 6RY1703-0AA01?
Siemens 6RY1703-0AA01 corresponds to C98043-A7001-L2; matching the L2 suffix avoids confusing it with earlier CUD1 hardware.
Which software range belongs with Siemens 6RY1703-0AA01?
The L2 control electronics supplied as Siemens 6RY1703-0AA01 are assigned to software release 3.0 and higher.
Where are the two serial paths located on 6RY1703-0AA01?
G-SST1 is reached at X300 through the PMU path, while G-SST2 for 6RY1703-0AA01 is available at terminals 56–60.
Can an external 24 V source be applied to the P24 point of 6RY1703-0AA01?
No. The P24 point on 6RY1703-0AA01 supplies its binary-input circuit and is not intended for an external feed.
What should be verified before using an encoder with 6RY1703-0AA01?
Confirm the encoder wiring and the 200 mA limit of the P15 encoder supply provided by 6RY1703-0AA01.
How can current feedback be checked at the terminal level on Siemens 6RY1703-0AA01?
Terminal 12 on Siemens 6RY1703-0AA01 provides the current actual-value signal, reaching 5 V at rated current.
