The 6SE7090-0XX84-0AB0 Control Board is the central processing unit within the SIMOVERT MASTERDRIVES frequency inverter system, commonly designated as the CUVC (Control Unit Vector Control) module.
Basic Terminal Strips
Encoder Feedback Connection
Stackable Expansion Slots
The Siemens 6SE7090-0XX84-0AB0 control board connects to the power drive layer of the inverter. Internal logic chips generate pulse-width modulation (PWM) trigger pulses based on the calculated vector waveforms, and these pulse signals are sent to the IGBT drive circuit of the inverter bridge through an internal ribbon cable.
Simultaneously, the module monitors the hardware status of the inverter power section through the backplane bus, including the V and W phase current feedback signals collected by current transformers and the voltage data from the intermediate DC link. This hardware feedback mechanism allows the control board to respond to electrical abnormalities such as overcurrent, short circuits, or overvoltage within milliseconds, blocking pulse outputs to protect the inverter power devices.

Steel Smelting
Regulates the torque and speed of electric motors for continuous casting straighteners.
Steel Rolling Industry
Controls the dynamic speed of primary drive motors for hot or cold rolling mills.
Paper Manufacturing
Coordinates the synchronous speed of multi-motor drive systems in high-speed paper machines.
Cement Manufacturing
Regulates the low-speed, high-torque output of primary drive motors for large rotary kilns.
Mining Industry
Controls the electrical drive systems of heavy-duty belt conveyors and mine hoists.
Oil Extraction
Regulates the operational speed of mud pumps and drawworks on offshore or onshore drilling rigs.
During field replacement of a failed 6SE7090-0XX84-0AB0 module, technicians must disconnect both the AC main power and the 24V control power, waiting until the DC link capacitors are discharged. Operational parameters, motor model data, and application macros reside within a removable EEPROM chip on the board; swapping this parameter chip onto the replacement board eliminates the need to manually re-enter hundreds of parameter codes.
This board integrates dedicated microprocessors to execute closed-loop or open-loop vector control algorithms. Serving as the primary processor of the drive system, it samples speed and current feedbacks, calculates speed and torque regulation loops, and directly outputs pulse-width modulation (PWM) signals to the inverter firing circuits for precise motor control.
