SIEMENS 6SL3040-0JA02-0AA0 – SINAMICS S110 CU305 PN Control Unit | Precision Servo Drive Controller
Engineering Background
The SIEMENS 6SL3040-0JA02-0AA0 is the CU305 PN Control Unit for the SINAMICS S110 single-axis servo drive platform — Siemens’ dedicated solution for high-precision positioning tasks in machine tool, packaging, and handling automation. Designed to operate seamlessly within the SINAMICS S110 drive system, this control unit integrates PROFINET IO communication, enabling deterministic real-time control over servo axes in demanding industrial environments.
Product Positioning
Targeted at OEM machine builders and system integrators who require a compact, high-performance servo controller with native SIMATIC S7 / TIA Portal integration. The CU305 PN is the preferred choice when PROFINET-based motion control, Safety Integrated functions, and single-axis positioning accuracy are non-negotiable requirements.

System Architecture & Signal Flow
The 6SL3040-0JA02-0AA0 CU305 PN sits at the top of the SINAMICS S110 drive train. The PLC (SIMATIC S7 / S7-1500) communicates via PROFINET to the CU305 PN, which processes motion setpoints and transmits torque/speed commands to the connected Power Module (PM340) via the internal drive bus. Encoder feedback is returned through DRIVE-CLiQ or conventional encoder interfaces, closing the position loop at the control unit level. Safety signals (STO) are hardwired directly to the CU305 PN terminal strip, ensuring fail-safe operation independent of the fieldbus.

Technical FAQ
Q: Is the 6SL3040-0JA02-0AA0 compatible with SIMATIC S7-1500 via PROFINET?
A: Yes. The CU305 PN supports PROFINET IO RT and IRT, fully compatible with S7-300, S7-400, and S7-1500 controllers using standard GSD/GSDML device files.
Q: Which Power Modules are compatible with this Control Unit?
A: The CU305 PN is designed for use with SINAMICS S110 PM340 Power Modules (booksize format). Refer to the SINAMICS S110 system manual for the complete compatibility matrix.
Q: Can STO be used without a safety PLC?
A: Yes. STO via terminals operates independently of the fieldbus and can be triggered by a hardwired safety circuit (e.g., emergency stop relay), meeting SIL 2 / PLe Cat. 3 requirements without a safety-rated PLC.
Q: What software is required for commissioning?
A: Siemens STARTER (standalone) or TIA Portal with the Startdrive add-on. Both support full parameterization, auto-tuning, and online diagnostics for the CU305 PN.
Q: Is this a new or refurbished unit?
A: Konmask.com supplies both new OEM stock and professionally refurbished units. Product condition is clearly stated on the listing. Contact us to confirm availability of new stock.
