Description
Product Overview
In a Robicon Perfect Harmony medium-voltage drive, the controller depends on dedicated interface hardware to exchange signals with the wider drive system. The Siemens Robicon A1A10000423.00M is identified in Siemens GH180 / Perfect Harmony spare-parts references as a firmware-equipped System I/O board for the NXG/NXGII controller platform. It is a drive-specific control assembly, not a general-purpose PLC I/O module. Its replacement must be assessed within the installed controller architecture and the drive’s production bill of materials.
The board appears in the same NXGII spare-parts list as the single-board computer and keypad adapter, modulator board, fiber-optic link board, communications board, and signal conditioning board. Those assemblies have separate functions, so a drive alarm involving I/O, communications, or power-cell control does not automatically establish that the System I/O board has failed. Check the alarm history, connector condition, associated wiring, and controller diagnostics before replacing hardware. The Siemens order number 6SR0960-0CB02-0AD0 and legacy reference LDZ10000423.00C provide additional identification points when comparing the installed board with a proposed spare.
For maintenance planning, the Siemens Robicon A1A10000423.00M is relevant to spare-parts management for supported NXG/NXGII drive installations. Since the board is listed as firmware-equipped, procurement should account for both the hardware revision and the software configuration. Confirm the full part number, revision marking, and applicable Siemens documentation before installation. Do not assume that a board with a similar designation or matching connectors is a valid substitute. For critical applications, request photographs of the actual unit and available functional-test records, and confirm the replacement procedure and commissioning checks with the responsible drive service team.
Product Introduction
A System I/O fault can affect drive control functions, but replacing the board without checking the associated wiring and diagnostics may not resolve the problem. The A1A10000423.00M is cataloged as a firmware-equipped System I/O board for the Robicon NXG/NXGII controller.
Before ordering, match the installed board’s part number and revision to the drive documentation. Confirm firmware requirements, condition, and the exact replacement reference before scheduling maintenance.

Frequently Asked Questions
Q1. What does the Siemens Robicon A1A10000423.00M do?
It is a firmware-equipped System I/O board used in the Robicon NXG/NXGII controller architecture. Its exact I/O functions depend on the board revision and drive configuration.
Q2. Is A1A10000423.00M a standard PLC I/O card?
No. It is a drive-specific PCA intended for the Robicon Perfect Harmony control system. Do not treat it as a generic PLC module based on the I/O designation alone.
Q3. Can I substitute another revision or a board with a similar number?
Only if the applicable Siemens documentation or an approved engineering cross-reference confirms compatibility. The Perfect Harmony operating instructions advise replacing components with the same part number and revision unless otherwise specified.
Q4. Can I hot-swap this board while the drive is running?
Do not assume hot-swap support. Follow the drive-specific isolation and stored-energy discharge procedure, along with site lockout/tagout requirements. Work on medium-voltage drive equipment should be performed by qualified personnel.
Q5. Does it support firmware v3.1?
A specific compatibility statement for firmware v3.1 has not been verified. Confirm the controller generation, installed software version, board revision, and any required firmware-loading procedure before commissioning.
Q6. Will replacing the System I/O board erase drive parameters?
That depends on the control architecture and where the relevant settings are stored. Back up accessible configuration data and record the existing board details before replacement. Confirm whether the replacement requires firmware loading, configuration, or additional commissioning.
Q7. What should I request when buying a replacement?
Request clear photographs of the actual board label, full part number, revision markings, connectors, and condition. Ask for functional-test evidence where available, plus written confirmation of compatibility with the installed drive. Clarify whether the unit is new, unused surplus, repaired, or refurbished, and confirm the warranty and return terms before purchase.
