Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Siemens 6SN1145-1BA01-0BA0 is a regulated infeed and regenerative feedback module (E/R module) designed for the SIMODRIVE 611 modular drive system. Functioning as a central power unit in industrial automation setups, this infeed module converts incoming AC mains power into a stable, regulated DC link supply for multi-axis drive line-ups. It delivers a continuous power rating of 16 kW with a peak power capability of 21 kW under closed-loop control, protecting connected axis controllers and drives from incoming line voltage fluctuations. Physical features include direct panel integration with internal forced-air cooling and an integrated mains contactor equipped with a normally closed (NC) break contact for controlled safety isolation.
Interfacing directly with SIMODRIVE 611-A analog and SIMODRIVE 611-D digital drive configurations, the 6SN1145-1BA01-0BA0 connects to drive modules through the internal SIMODRIVE bus architecture and common DC link busbars. The module provides stable energy to high-performance machine tools and robotic systems operating Siemens 1FT, 1FK, and 1PH servo and induction motors. Commissioning a replacement unit requires confirming correct DC link jumper installations, verifying control wiring to the internal mains contactor break contact, and aligning parameter settings with the host system. ABC Industrial Parts can supply replacement modules to assist in restoring operational capability without requiring a full drive system overhaul.
Operating as a closed-loop system, the 6SN1145-1BA01-0BA0 actively monitors power flow and directs excess kinetic braking energy back into the power grid to reduce energy losses. Initial line checks during machine downtime should focus on verifying three-phase input balance, proper activation of the integrated mains contactor, and adequate clearance for internal forced-air circulation. Because internal power component degradation or board-level failures cannot be serviced in the field, exchanging a faulty unit for a tested replacement through ABC Industrial Parts offers a fast and effective path to resume production.

Replacement and Spare Part Considerations
When replacing a failed Siemens 6SN1145-1BA01-0BA0 module, verify that the existing cabinet space accommodates its physical dimensions of 300 mm in height and 600 mm in depth, with a total weight of 10 kg. Proper positioning within the SIMODRIVE 611 rack is essential to ensure that the internal forced-air cooling vents remain unobstructed by surrounding cabling or trunking.
The direct successor designated for this unit is part number 6SN1145-1BA01-0BA2. Both the original 6SN1145-1BA01-0BA0 and its successor maintain full operational compatibility with SIMODRIVE 611-A and 611-D drive frameworks, offering identical 16 kW continuous and 21 kW peak power handling capacities without requiring physical modification to the mounting panel.
Frequently Asked Questions
What is the primary function of the Siemens 6SN1145-1BA01-0BA0 in a machine drive system?
