Siemens 6AU1400-2PA02-0AA0 Replacement CF Card for SINAMICS SIMOTION

Product Overview

Siemens 6AU1400-2PA02-0AA0 Replacement CF Card for SINAMICS SIMOTION: Seamless Transition & Legacy System Upgrade

The Siemens 6AU1400-2PA02-0AA0 is a Compact Flash (CF) Card designed for use within the SINAMICS and SIMOTION motion control platform — one of Siemens’ most widely deployed drive and motion coordination systems in industrial automation. As legacy SIMOTION D and SINAMICS S120 installations age, many facilities face the challenge of sourcing this CF card as a direct replacement for failed, corrupted, or end-of-life memory modules. TOPNLMS stocks verified units of the 6AU1400-2PA02-0AA0 to support your retrofit, upgrade, or emergency replacement requirements with minimal disruption to production.

This CF card serves as the primary program and parameter storage medium for SIMOTION D controllers — including the SIMOTION D410-2, SIMOTION D425-2, SIMOTION D435-2, and SIMOTION D445-2 — as well as compatible SINAMICS S120 Control Units such as the CU320-2 PN and CU320-2 DP. The card stores drive parameters, motion programs, technology objects, and firmware, making it the single most critical component for system recovery after a controller failure or planned upgrade.

When migrating from an older SIMOTION D4x5 or SINAMICS S120 installation, engineers frequently encounter situations where the original CF card has become corrupted due to power interruptions, excessive write cycles, or physical damage. In these scenarios, a direct replacement with the 6AU1400-2PA02-0AA0 allows the existing project data — previously backed up via SIMOTION SCOUT or STARTER commissioning software — to be restored without rewriting the entire drive configuration from scratch. This dramatically reduces commissioning time and minimizes the risk of parameter entry errors during recovery.

From a wiring and installation standpoint, the 6AU1400-2PA02-0AA0 is a plug-in replacement that requires no additional cabling, terminal block modifications, or rack changes. It inserts directly into the CF card slot on the SIMOTION D or compatible SINAMICS Control Unit, maintaining the same physical footprint and connector interface as the original factory-installed card. No changes to the control cabinet layout, DIN rail mounting, or power supply wiring are required, which is a critical advantage when working within space-constrained panels housing components such as the SINAMICS S120 Power Module PM340 or booksize Motor Modules.

Communication protocol compatibility is fully preserved. The SIMOTION D platform communicates via PROFINET IO and/or PROFIBUS DP depending on the Control Unit variant. The 6AU1400-2PA02-0AA0 stores the network configuration, device names, and IP address assignments as part of the project data. After card replacement and project restore, the controller resumes its role as a PROFINET controller or PROFIBUS master without requiring re-parameterization of connected I/O devices, distributed peripherals, or HMI panels such as the Siemens SIMATIC HMI TP900 or KTP700 Basic.

For facilities upgrading from older SIMOTION D4x5 hardware to current D4x5-2 variants, the CF card migration path is well-defined. The project must be converted using SIMOTION SCOUT TIA and re-downloaded to the new card. During this process, engineers typically also review and update associated components including SINAMICS S120 Line Modules, Sensor Modules SMC30 for encoder feedback, and Terminal Modules TM31 or TM41 for analog and digital I/O expansion. TOPNLMS can supply these complementary components alongside the 6AU1400-2PA02-0AA0 to support a complete system refresh.

Downtime reduction is the primary driver for most 6AU1400-2PA02-0AA0 procurement requests. Production lines dependent on SIMOTION-coordinated multi-axis motion — such as packaging machinery, printing presses, textile equipment, and CNC transfer lines — cannot tolerate extended outages. Our in-stock availability and same-day dispatch capability from Xiamen ensures that replacement units reach customers across Asia, Europe, and the Americas within the shortest possible lead time. All units are tested prior to shipment and supplied with full traceability documentation.

Seamless Upgrade Solutions

A successful SIMOTION or SINAMICS S120 upgrade rarely involves a single component. When replacing the 6AU1400-2PA02-0AA0 CF card as part of a broader system modernization, the following components are commonly required in the same retrofit scope:

The SINAMICS S120 CU320-2 PN Control Unit is the host controller that accepts the CF card and manages drive coordination across multiple axes. If the Control Unit itself has failed alongside the CF card, both must be replaced together to restore system operation. Similarly, the SINAMICS S120 Active Line Module and associated Motor Modules in booksize or chassis format may require firmware updates stored on the new CF card to maintain compatibility with the refreshed control software.

For I/O expansion and signal conditioning within the same control cabinet, the SINAMICS Terminal Module TM31 provides analog inputs/outputs and digital I/O that interface directly with the SIMOTION D controller via DRIVE-CLiQ. The Sensor Module Cabinet-Mounted SMC30 handles encoder signal processing for servo axes and must be correctly parameterized as part of the post-replacement commissioning sequence. These modules retain their own parameters independently of the CF card, simplifying the restoration process.

Communication infrastructure components such as the SIMATIC NET CP 343-1 PROFINET module or PROFIBUS DP repeaters may also need attention during a migration, particularly if the network topology is being updated alongside the drive system. On the HMI side, operator panels such as the SIMATIC HMI KTP900 Basic connected via PROFINET will automatically reconnect to the restored SIMOTION controller once the CF card project is reloaded and the controller resumes normal operation.

For customers performing a full cabinet retrofit, TOPNLMS can also supply the SINAMICS S120 Booksize Base Unit BU15 and associated 24 VDC SITOP power supply modules to complete the hardware refresh. Our technical team can advise on component compatibility and assist with BOM verification prior to order placement.

Retrofit Guidance FAQ

Q: Can I use the 6AU1400-2PA02-0AA0 as a direct replacement for a failed CF card without reprogramming?
A: Yes, provided you have a valid project backup from SIMOTION SCOUT or SCOUT TIA. Restore the project to the new card using the commissioning software, insert the card into the Control Unit, and power up. The controller will load the project automatically. No rewiring is required.

Q: Is this CF card compatible with both PROFINET and PROFIBUS variants of the SIMOTION D controller?
A: Yes. The 6AU1400-2PA02-0AA0 is compatible with SIMOTION D controllers equipped with either PROFINET IO or PROFIBUS DP interfaces. The communication protocol configuration is stored within the project data on the card itself.

Q: What happens to my drive parameters and motion programs after CF card replacement?
A: All drive parameters, technology objects, motion programs, and network configurations are stored on the CF card. After replacing the card and restoring your project backup, all settings are recovered exactly as they were before the failure. No manual re-entry of parameters is required.

Q: Does the physical size of the 6AU1400-2PA02-0AA0 match the original card in my SIMOTION D unit?
A: Yes. The card uses the standard CompactFlash form factor and inserts directly into the existing CF slot on the SIMOTION D or SINAMICS CU320-2 Control Unit. No cabinet modifications, bracket changes, or additional mounting hardware are needed.

Q: Can TOPNLMS supply this card pre-loaded with firmware?
A: We supply the card in its standard factory state. Firmware and project data must be loaded using SIMOTION SCOUT TIA according to Siemens’ commissioning procedure. Please contact our technical team if you require assistance with the firmware version compatibility for your specific hardware revision.

Q: What is the lead time and shipping arrangement?
A: Units are in stock in Xiamen and dispatched same day or next business day. We ship via DHL Express, FedEx, and UPS to destinations worldwide. Typical transit times are 3–5 business days to Europe and North America, and 1–3 business days within Asia.
