Siemens 6SE7023-4TC84-1HF3 SIMOVERT MASTERDRIVES PEU Power Output Module
A SIMOVERT MASTERDRIVES power output module identified for 34 A equipment on the documented DC-link class.
Product Profile
Siemens 6SE7023-4TC84-1HF3 is a SIMOVERT MASTERDRIVES PEU power output module supplied as a spare for 34 A equipment in the 510–620 V DC class.
The complete article includes the 1HF3 suffix and must be matched to the installed drive. Service work requires the MASTERDRIVES isolation, discharge, ESD and recommissioning procedure for the host equipment.
Technical Data
System Role
The module is identified as a power-output spare rather than a complete standalone drive.
The 34 A and DC-link class define the equipment boundary documented for the PEU.
The full article suffix remains part of receiving and replacement control.
Recommissioning is completed inside the host MASTERDRIVES system with the correct control and protection hardware.
Compatibility & Service
- Identify the host drive, control unit, DC-link source, cooling arrangement and exact PEU label.
- Isolate the incoming supply and DC link, wait the documented discharge time and prove absence of hazardous voltage.
- Record gate, phase, feedback and protective-earth connections before removal.
- After installation, complete insulation and power-stage checks, review diagnostics and test output symmetry under the approved procedure.
Applications
- Service of SIMOVERT MASTERDRIVES equipment documented for the 34 A PEU class.
- Power-section maintenance supported by the full drive nameplate and circuit record.
- Legacy spare stocking for a known 1HF3 installation.
- Controlled repair and recommissioning during a planned drive shutdown.
FAQ
Is 6SE7023-4TC84-1HF3 a complete variable-speed drive?
No. Siemens identifies it as a PEU power output module supplied for the corresponding MASTERDRIVES equipment class.
What must be confirmed beyond the 34 A current class?
Confirm the complete 1HF3 article, host drive configuration, DC-link class, control hardware, connectors, cooling and service documentation.
Why is the DC link still dangerous after the mains supply is opened?
Stored energy can remain in the converter capacitors. Follow the documented wait time and verify absence of voltage before touching the PEU.
What board-level records are needed for a repair evaluation?
Provide both sides, label and revision, connector condition, damaged areas, host fault codes, failure circumstances and any earlier repairs.
What should be verified before energizing the serviced PEU?
Check connection mapping, protective earth, insulation, cooling, fasteners and the host-specific commissioning sequence before controlled power-up.
