System Architecture & Signal Flow
The 6SE7034-6EC85-0JA0 operates as the inverter stage within a SIMOVERT MASTERDRIVES system. The typical signal and power flow is:
- AC Mains Input → Rectifier/Active Front End (AFE) module converts to DC bus voltage
- DC Bus → 6SE7034-6EC85-0JA0 inverter module receives DC power
- IGBT Switching → PWM-controlled IGBT bridge synthesizes variable-frequency, variable-voltage AC output
- Motor Output → Three-phase AC output drives the connected induction or synchronous motor
- Control Interface → CU (Control Unit) communicates via fiber optic or PROFIBUS DP for speed/torque setpoints and feedback
This modular topology allows independent replacement of the inverter module without disturbing the rectifier, control unit, or other drive modules sharing the same DC bus.

Technical FAQ
Q: Is the 6SE7034-6EC85-0JA0 a standalone drive or a module?
A: It is an inverter module designed for integration into a SIMOVERT MASTERDRIVES cabinet system. It requires a compatible rectifier/AFE module, control unit (CU), and DC bus infrastructure to operate.
Q: What control unit (CU) is compatible with this module?
A: This module is compatible with Siemens SIMOVERT MASTERDRIVES CU series control units, including the CU3 and VC (Vector Control) variants. Please consult the Siemens SIMOVERT MASTERDRIVES configuration manual (Order No. 6SE7087-6QX70) for exact pairing.
Q: Can this module be used with a third-party rectifier?
A: Not recommended. The DC bus voltage and communication protocols are optimized for Siemens SIMOVERT MASTERDRIVES rectifier modules. Third-party rectifiers may cause compatibility and safety issues.
Q: What is the replacement procedure for a failed module?
A: Isolate the DC bus, discharge capacitors per Siemens safety procedure, disconnect fiber optic and power connections, slide out the module, insert the replacement, and recommission via the CU parameter set. Full procedure is documented in Siemens Service Manual 6SE7087-6CX87-2DA0.
Q: Does Konmask.com provide commissioning support?
A: Yes. Our technical team provides remote commissioning guidance via email and video call. On-site support can be arranged for large-scale projects.
