More Information

Overview Manuals Analog Paths Serial Interfaces Memory Boundary Diagnostic Signals

Features:

  • Coordinates armature and field control in SIMOREG DC-MASTER.
  • Processes analog, serial and pulse-encoder signal paths.
  • Uses the external A7009 EEPROM for non-volatile parameters.
The CUD1 architecture places converter calculations and signal conversion on one control board.

Ground-referenced analog channels connect measured values and command inputs to the control processor.

Hardware version L1 belongs to product states A1/A2 and is paired with software generations 1.xx and 2.xx.

The Siemens C98043-A7001-L1 6RY1703-0AA00 CUD1 Control Electronics Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

How measured values enter and leave CUD1

  • Input 1: Terminals 4/5 feed the main setpoint or analog-select channel.
  • Input 2: Terminals 6/7 provide a second ground-referenced analog channel.
  • Outputs: Terminals 14 and 16 carry configurable analog values.
  • Current signal: Terminal 12 delivers 5 V at rated armature current.

Two independent communication routes

  • G-SST1: X300 supports the first RS232 or RS485 path.
  • G-SST2: Terminals 56–60 form the second RS485 path.
  • Reference: Each serial route includes its defined signal ground.
  • Separation: The two interfaces occupy different physical connection points.

Where non-volatile data is retained

  • Storage device: Parameter data resides in the EEPROM on A7009.
  • Board link: CUD1 reaches that memory through connector X109.
  • Power loss: Stored parameter and process data remain non-volatile.
  • Hardware rule: L1 hardware belongs to product states A1 and A2.

Fault checks associated with CUD1

  • F063: Verifies analog input and output compensation data.
  • F064: A hardware watchdog checks the firing-pulse calculation cycle.
  • F068: Monitors the main setpoint and analog measuring channels.
  • Saturation limit: Inputs above about 11.3 V can trigger F068.
Description
Siemens C98043-A7001-L1 6RY1703-0AA00 is the CUD1 control electronics board in the SIMOREG DC-MASTER platform. It performs open-loop and closed-loop control for the armature and field while coordinating the converter's measured values, command signals and firing-pulse calculations.

Analog processing on C98043-A7001-L1 6RY1703-0AA00 includes ground-referenced inputs at terminals 4/5 and 6/7, analog outputs at terminals 14 and 16, and a real-time armature-current signal at terminal 12. The terminal-12 output reaches 5 V when the rated armature current is present.

Two serial paths are available to C98043-A7001-L1 6RY1703-0AA00. The first operates through X300 for RS232 or RS485 communication, while the second uses terminals 56–60 as an RS485 interface. Pulse-encoder evaluation and KTY84/PTC motor-temperature sensing are integrated into the surrounding CUD1 signal structure.

Non-volatile parameter values are not stored on C98043-A7001-L1 6RY1703-0AA00 itself. They reside in the EEPROM on the A7009 rear-panel wiring assembly and communicate with CUD1 through X109; product states A1 and A2 require software versions 1.xx or 2.xx.

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 software versions belong with Siemens C98043-A7001-L1 6RY1703-0AA00?
Product states A1 and A2 with the L1 CUD1 board are limited to software versions 1.xx and 2.xx.
Where are parameters retained when Siemens C98043-A7001-L1 6RY1703-0AA00 loses power?
The non-volatile values are held in the EEPROM on A7009 and accessed from CUD1 through X109.
What should be checked when F068 appears with Siemens C98043-A7001-L1 6RY1703-0AA00?
Inspect the analog measuring circuits at terminals 4/5 and 6/7; input levels above about 11.3 V can saturate a channel.
How do the two serial routes differ on Siemens C98043-A7001-L1 6RY1703-0AA00?
G-SST1 is available at X300 as RS232/RS485, while G-SST2 uses terminals 56–60 as RS485.
Can Siemens C98043-A7001-L1 6RY1703-0AA00 be exchanged with the L2 hardware without checking software?
No. L1 is tied to software 1.xx–2.xx, whereas the L2 generation is associated with software 3.xx.
Which output gives a direct current-related signal on Siemens C98043-A7001-L1 6RY1703-0AA00?
Terminal 12 provides the real-time armature-current signal and reaches 5 V at rated current.
