Siemens 6FC5450-3AY01-3AH0 | SINUMERIK 810D System Software for CCU1 — PC Card, SW Version 3.x

Part Number: 6FC5450-3AY01-3AH0

Manufacturer: Siemens AG (Germany)

Product Type: CNC System Software — PC Card (Export Version)

CNC Platform: SINUMERIK 810D

CNC Software on a Card

The 6FC5450-3AY01-3AH0 is the SINUMERIK 810D system software for the CCU1 control unit, delivered on a PC card. The software card is the firmware and operating system for the CCU1 — without it, the CCU1 cannot perform any CNC control function. This PC card is both the delivery medium and the licensing vehicle for the SINUMERIK 810D software.

SINUMERIK 810D is Siemens' compact CNC for mid-range machine tools — milling machines, turning centres, and machining centres requiring up to 4 controlled axes. The CCU1 is the first-generation hardware variant of the 810D control platform, integrating the NC processor, PLC, and axis control in a single compact housing.

Version 3.x of the 810D software introduced significant capability improvements over earlier versions — extending axis count support, improving interpolation performance, and adding new PLC function blocks. The "-3AH0" suffix in the order number identifies this as export-controlled and single-licence.

Licence and Export Note

The 6FC5450-3AY01-3AH0 carries export control designations. It is a single licence — the software authorises one installation on one CCU1 unit. The licence is tied to the PC card, not the CCU1 hardware. Transferring the card to a different CCU1 transfers the software licence along with it.

Siemens' SINUMERIK 810D has reached its end-of-life phase. Replacement PC cards and software licences are sourced from the CNC aftermarket or Siemens' service channels, subject to availability.

Key Specifications

FAQ

Q1: The CCU1 shows a boot error after the PC card was replaced. What should be checked first?

Confirm the PC card is fully and correctly seated in the CCU1's card slot. A partially inserted card is the most common cause of boot errors after card replacement. If seating is confirmed, verify the software version on the card is compatible with the CCU1 hardware revision — some CCU1 hardware versions require a minimum SW version.

Q2: Can the 6FC5450-3AY01-3AH0 PC card be used in a SINUMERIK 840D or other platform?

No. The 6FC5450 series software is specific to the SINUMERIK 810D / CCU1 architecture. A 840D uses a different NCU hardware with incompatible software. Each SINUMERIK platform requires its own matching software and hardware.

Q3: The PC card was damaged. Can the software be transferred to a blank card?

SINUMERIK software is licence-bound to the specific card. It cannot be copied to a blank card without a new licence. If the original card is damaged, a replacement card with the same software version and a new licence must be obtained through Siemens' service channel or the CNC aftermarket.

Q4: The machine uses SW version 3.3. Is 6FC5450-3AY01-3AH0 the correct card?

The "3AY01" part of the order number confirms SW version 3.x compatibility, and sub-versions such as 3.3 are within this range. However, confirm the exact sub-version available on the card with the supplier — Siemens released multiple sub-versions within the v3.x branch. Run a software version check on the control after installation.

Q5: Can SINUMERIK 810D machine data (NC parameters) be restored after replacing the PC card?

Yes, if a machine data backup exists. Machine data is saved using the SINUMERIK backup functions (via Siemens PCIN tool or a memory card). After fitting the replacement software card, restore the backup. Without a backup, the machine must be recommissioned from the NC parameter manual and machine tool builder documentation.
