Siemens 6SE7041-8EK85-1HA0 Rectifier Interface Module
A legacy PER2 spare for the rectifier interface of matching H- and K-design infeed and regenerative supply units.
Key Information
6SE7041-8EK85-1HA0 is a Siemens SIMOVERT MASTERDRIVES rectifier-interface spare identified as module PER2. It belongs to the control interface between the electronics and power section of the correct infeed or regenerative feedback supply unit.
Selection must be based on the complete host-unit article number and voltage family. Physical similarity to another PER board is not sufficient evidence of interchangeability.
Functions
- Provides the specified rectifier-interface function inside matching H- and K-design supply units.
- Supports the internal control connection required by the infeed or regenerative power section.
- Preserves the documented PER2 execution during maintenance of an installed MASTERDRIVES system.

Installation
- Record the complete supply-unit nameplate, hardware state and every connector position before removal.
- Isolate the mains and DC link, prove discharge and follow the approved electrostatic-discharge procedure.
- Compare board identity, mounting points and connector coding before transferring any plugs.
- After installation, verify unit diagnostics, precharge or infeed behavior and regenerative operation where fitted.
Lifecycle
- Retain the original board label, host serial number and commissioning backup with the service record.
- Treat later SINAMICS migration as a system-engineering project rather than a board-only substitution.
- Keep a tested spare under controlled storage when continued MASTERDRIVES operation is business-critical.
FAQ
Can 6SE7041-8EK85-1HA0 replace 6SE7041-8EK85-0HA0?
Do not assume so. The final execution digit distinguishes the board version and must be checked against the host documentation.
What host information is needed for 6SE7041-8EK85-1HA0?
Provide the complete supply-unit article, serial number, hardware version, cabinet photographs and the removed-board label.
Is 6SE7041-8EK85-1HA0 a complete infeed unit?
No. It is an internal rectifier-interface spare for the correct MASTERDRIVES supply unit.
Can 6SE7041-8EK85-1HA0 be selected from board appearance alone?
No. Connector layout may look similar across revisions, while voltage class, host design and interface execution remain decisive.
What should be tested after a 6SE7041-8EK85-1HA0 exchange?
Check internal diagnostics, charging sequence, DC-link response, enable chain, fault history and regenerative operation where applicable.
How should a future replacement for 6SE7041-8EK85-1HA0 be planned?
Capture the complete drive topology, motors, feedback, fieldbus, safety, braking and regenerative requirements before evaluating a SINAMICS migration.
