Description

The Siemens 6RY1803-0AA00-0AA1 (also referenced as C98043-A7100-L3 in drive documentation)​ is a standard control electronics board / regulator insert​ used in SIMODRIVE 611 / SIMODRIVE 611D / SINUMERIK 810D / 840D servo drive systems. It houses the digital signal processor, feedback evaluation logic (resolver / EnDat / SinCos), and communication interface to the NCU or PLC. The variant 6RY1803-0AA05-0AA1​ is a related sub-version (different firmware / I/O population — verify compatibility with your existing drive rack).
These boards plug into the drive control module (CCU / I/R module)​ of the Simodrive 611 analog/digital rack and are NOT interchangeable with the power sections — they contain all intelligence for current control loops, position loop closure (when used with NCU), and diagnostic LEDs.

Key Features

  • Function: Digital servo drive control electronics — processes setpoint from NCU/PLC, closes current & velocity loops, evaluates motor feedback.
  • Compatible Drives: SIMODRIVE 611 (Analog & Digital versions), SIMODRIVE 611D, integrated in SINUMERIK 810D / 840D sl drive racks.
  • Feedback Supported: Resolver, 1Vpp Sin/Cos (Heidenhain-compatible), EnDat 2.1/2.2 (via plugged measuring card).
  • Interface: Connects to NCU via IM (Interface Module) or directly to Profibus/DevNet option card.
  • Diagnostics: Status LEDs for Ready, Enable, Fault, Feedback status.
  • Country of Origin: Germany

Notes
6RY1803-0AA00-0AA1​
Control Electronics Board (Std. w/ Terminals, 32 MB* — referring to optional memory card C98043-A7100-L3 sometimes bundled)
Most common version for 611 Digital
C98043-A7100-L3​
Associated Memory / Option Card or Drive Electronics Insert (appears on nameplate / docs)
Often listed alongside 6RY1803 — verify if you need main board or plug-in daughter card
6RY1803-0AA05-0AA1​
Variant / Later Revision of same family
Check firmware compatibility with your existing I/R module
⚠️ Critical Replacement Notes:
  1. Record Parameters: Before swapping, save all drive parameters via SimoCom U / STARTER / SINUMERIK HMI​ — especially if the new board is blank.
  2. Daughter Cards: Ensure any plugged measuring cards (EnDat / Resolver / SinCos interface) are transferred from old board to new.
  3. Firmware Match: The control electronics version must be compatible with the IM (Interface Module)​ and NCU software version​ — mismatches cause F0xxxfaults.
  4. ESD Precautions: Board is ESD-sensitive — ground yourself and use original antistatic packaging.
