The 6SE7090-0XX84-0BJ0 is a SIMOVERT MASTERDRIVES series CUSA control board module used as a replacement part to govern active front end (AFE) infeed and regenerative feedback operations, containing the motherboard, embedded V2.XX firmware, internal bus plug connectors, and external signal wiring terminals.
The primary function of the 6SE7090-0XX84-0BJ0 is to manage the line-side insulated-gate bipolar transistors in the AFE rectifier. Through its internal processing, it executes four-quadrant operation, enabling bidirectional power control that permits kinetic braking energy from the motor to be converted and returned back to the AC supply grid. The control algorithms on the board regulate the line current to maintain a sinusoidal current control profile, minimizing total harmonic distortion.
Additionally, it continuously monitors and adjusts the phase angle to stabilize the power factor near 1.0, while maintaining a constant DC link voltage regardless of fluctuations in the input mains voltage or changes in the motor load.
The 6SE7090-0XX84-0BJ0 SIEMENS SIMOVERT MASTERDRIVES module is available for purchase and support from Apter Power beyond the manufacturer's (OEM) End-Of-Life (EOL) date.

Metal Rolling Mills
Controls AFE units in main drive systems for steel rolling mills to manage rapid acceleration and regenerative braking energy during steel deformation processes.
Mining and Minerals Processing
Applied to high-power overland conveyor belts and mine hoists to feed gravitational energy back into the power grid during downhill transport or material lowering.
Oil and Gas Extraction
Used on top drives, drawworks, and mud pumps of drilling rigs to stabilize the DC bus voltage under cyclic, heavy-load fluctuations.
Paper and Pulp Manufacturing
Installed in multi-motor sectional drive systems of paper machines to maintain precise tension control and line speed synchronization.
Thermal Power Generation
Used on boiler feed pumps, induced draft (ID) fans, and forced draft (FD) fans to optimize electrical energy usage and regulate the flow rates of critical thermal loops.
Automotive Manufacturing Plants
Used on mechanical stamping presses and continuous assembly conveyor lines to prevent voltage drops caused by concentrated, pulsating load peaks.
Isolate all power supplies and verify capacitor discharge before servicing the 6SE7090-0XX84-0BJ0. Use Electrostatic Discharge grounding during handling.
Ensure the embedded V2.40 firmware parameters match the Active Front End hardware configuration. Do not insert into non-AFE slots like CUVC or CU2. Maintain an ambient operating temperature of 0°C to +50°C and remove dust periodically to prevent insulation breakdown.
The 6SE7090-0XX84-0BJ0 operates within standard MASTERDRIVES chassis units utilizing compatible AFE configurations and cannot function as a standard inverter control board (such as the CUVC or CU2) due to specific hardware limits and control software gating.
It is a control board for Siemens MASTERDRIVES AFE units.
