Siemens 6RY1803-0AA05-0AA1 Advanced CUD
An active SINAMICS DCM spare for the uncoated 32 MB Advanced CUD board C98043-A7100-L4 with terminals.
Key Information
6RY1803-0AA05-0AA1 is the Siemens spare-part order for SINAMICS DCM Advanced control electronics with terminals and 32 MB memory. The corresponding board label is C98043-A7100-L4.
The uncoated Advanced CUD can be assigned to the documented left or right CUD position; right-side configurations have additional system prerequisites. Siemens lists the spare as an active PM300 service product.
Functions
- Provides advanced closed-loop control and converter coordination in the SINAMICS DCM platform.
- Supports option G00 as the Advanced CUD left configuration.
- Can support a documented G11 right-side Advanced CUD arrangement when the system prerequisites are met.
- Provides the control platform required for supported communication and memory-card options.

Installation
- Confirm converter firmware, CUD position, connector board, CBE20 and memory-card arrangement.
- Create a full parameter/project backup and record the hardware label before isolation.
- Install under the SINAMICS DCM ESD, discharge and connector-handling procedures.
- Validate terminal I/O, communications, field and armature behavior, diagnostics and controlled operation.
Lifecycle
- Maintain both the 6RY order number and C98043 board identity in the service record.
- Use the spare-parts ordering channel and state whether accessories or connector boards are required.
- Review hardware/firmware compatibility before any converter software update.
FAQ
When should a quote use 6RY1803-0AA05-0AA1 instead of only C98043-A7100-L4?
Use the 6RY number for the Siemens spare order and retain the C98043 label as the physical-board identity and inspection reference.
What changes if 6RY1803-0AA05-0AA1 is being added rather than replaced?
A retrofit needs the appropriate connector board and an engineered slot/option arrangement; a like-for-like replacement may reuse the installed companion hardware after inspection.
Can 6RY1803-0AA05-0AA1 be ordered for a right-side Advanced CUD position?
Yes only within the documented G11 architecture, which requires an Advanced CUD on the left and the correct connector/option configuration.
Which accessories should be stated separately with 6RY1803-0AA05-0AA1?
Specify connector board, CBE20, memory card, terminals and any service/exchange requirement so the supply boundary is unambiguous.
What is the safest way to restore a project after fitting 6RY1803-0AA05-0AA1?
Match hardware and firmware first, restore a verified converter backup, then validate options, terminals, communications and controlled DC-drive behavior before production release.
