The Siemens 6SL3040-0LA01-0AA1 is a SINAMICS S120 Control Unit CU310 PN — a spare part for the modular drive system, carrying a PROFINET interface and shipped without a CompactFlash card. It sits in the control cabinet as the brains of a single-axis drive group, handling motion control, fieldbus communication, and safety functions through the S120 shared DC-link architecture.

Frequently asked questions
How do I get current pricing and availability for 6SL3040-0LA01-0AA1?
Submit an RFQ through the storefront. Pricing and stock are confirmed at quote time — no published figures are kept on this page.
What is the closest functional second-source to 6SL3040-0LA01-0AA1?
No direct second-source exists. The 6ES7314-1AE03-0AB0 is a Siemens S7-300 CPU, not a drive control unit — they share a manufacturer but serve completely different system architectures. The CU310 PN is specific to the SINAMICS S120 drive platform.
Will 6SL3040-0LA01-0AA1 drop into a panel specified around 6ES7314-1AE03-0AB0 without rewiring?
No. The 6ES7314-1AE03-0AB0 is a PLC CPU for the S7-300 rack; the CU310 PN is a drive control unit for the S120 DRIVE-CLiQ system. They use different backplanes, power supplies, and fieldbus protocols (PROFIBUS vs PROFINET). Rewiring the entire control section would be required.
