SIEMENS 6SN1145-1BA01-0BA2 – SIMODRIVE 611 Infeed/Regenerative Power Module | SIMODRIVE 611 Platform
Engineering Background
The SIMODRIVE 611 series represents Siemens’ flagship modular drive system for CNC machine tools, developed for high-dynamic servo and spindle applications. The 6SN1145-1BA01-0BA2 is a regulated infeed/regenerative feedback power module (Einspeisung mit Rückspeisefähigkeit) that provides a stable DC bus for downstream axis and spindle drive modules. It supports both motoring and regenerative braking energy feedback to the AC supply, making it the preferred choice for energy-efficient multi-axis CNC installations.
Product Positioning
Designed for procurement engineers and maintenance teams operating Siemens SINUMERIK 840D/810D CNC systems, this module is the power backbone of the SIMODRIVE 611 drive line. It is a direct OEM replacement for aging infeed modules in retrofit, repair, and new machine build projects across aerospace, automotive, and precision machining sectors.

- Compact Footprint: 200 mm wide module slot minimizes cabinet space in multi-axis configurations
System Architecture & Signal Flow
The 6SN1145-1BA01-0BA2 occupies the infeed position (leftmost slot) in the SIMODRIVE 611 drive line assembly. AC mains (3-phase, 380–480 V) enters the module, is rectified and regulated to a 600 V DC bus, and distributed via the internal DC bus bar to all connected axis and spindle drive modules (6SN1123/6SN1124 series). During deceleration, regenerative energy flows back through the module’s active front-end IGBT bridge to the AC supply. The module communicates drive-line status via the SIMODRIVE 611 internal bus to the SINUMERIK CNC controller.
Typical Drive Line Configuration:
AC Mains → [6SN1145-1BA01-0BA2 Infeed Module] → DC Bus → [Axis Modules ×N] → Servo/Spindle Motors

Technical FAQ
Q: Is the 6SN1145-1BA01-0BA2 compatible with SINUMERIK 840D sl?
A: Yes. This module is fully compatible with SINUMERIK 840D sl, 840D, and 810D CNC controllers when used within a standard SIMODRIVE 611 drive line.
Q: Can this module replace a 6SN1145-1BA00-0BA2 (non-regenerative version)?
A: Yes, with minor wiring modifications. The -1BA01- variant adds active regeneration capability; it is a functional superset of the -1BA00- non-regenerative module. Consult Siemens documentation or contact Konmask engineering for retrofit guidance.
Q: What is the maximum number of axis modules this infeed can support?
A: The 80 A continuous / 160 A peak rating supports up to 6–8 standard axis modules depending on individual axis current demand. A detailed power budget calculation is recommended for configurations exceeding 6 axes.
Q: Do you provide a test report with each unit?
A: Yes. A pre-shipment inspection report including visual check, label verification, and capacitor ESR test results is provided with every unit.
Q: What is the lead time for in-stock units?
A: In-stock units ship within 1–3 business days. For units sourced to order, lead time is typically 2–4 weeks. Contact us for real-time stock status.
