System Architecture & Signal Flow
The 6SE7037-0EK84-1JC2 operates as the inverter stage within a SIMOVERT MASTERDRIVES system. The rectifier/DC-link unit supplies the DC bus; this module converts DC bus power to variable-frequency AC output for the connected motor. Control signals are received via the onboard CUVC (Control Unit Vector Control) or an external control unit connected through the drive bus. PROFIBUS DP communication (via optional CBP2 board) enables real-time parameter access, fault diagnostics, and setpoint control from a SIMATIC S7 PLC or SCADA system.
Signal Flow: Grid AC → Rectifier → DC Bus → 6SE7037-0EK84-1JC2 Inverter Module → Motor AC Output

Technical FAQ
Q: Is the 6SE7037-0EK84-1JC2 compatible with SIMOVERT MASTERDRIVES MC (Motion Control)?
A: No. This unit is a Vector Control (VC) variant. MC and VC modules are not interchangeable. Confirm your existing system type before ordering.
Q: Can this module operate as a standalone inverter without a separate rectifier unit?
A: No. The 6SE7037-0EK84-1JC2 is an inverter-only module and requires a compatible MASTERDRIVES rectifier/DC-link unit to supply the DC bus.
Q: What encoder interface does this module support?
A: The CUVC control unit supports HTL/TTL incremental encoders. SSI absolute encoders require the SBP option board.
Q: Is PROFIBUS DP built in?
A: PROFIBUS DP requires the CBP2 option board, which is mounted on the CUVC. Confirm whether your unit includes this board or order separately.
Q: What is the warranty policy?
A: Konmask.com provides a 12-month warranty on all verified units. Contact support@konmask.com for warranty claims and RMA procedures.
