More Information

Overview Manuals Control AFE Design Configuration Safety

Features:

  • CUSA control regulates the Active Front End DC-link voltage.
  • Mains-angle-oriented vector control shapes a nearly sinusoidal line current.
  • Firmware V2.XX identifies the supported AFE control release.
Siemens 6SE7090-0XX84-0BJ0 provides the command and regulation layer for a SIMOVERT MASTERDRIVES Active Front End rather than serving as a stand-alone power converter.

Line-angle information arrives from the VSB, enabling the controller to coordinate the AFE inverter as energy moves from the mains into the DC link or returns toward the supply.

A complete arrangement combines the control module with the specified reactor, supply connecting module, CleanPower filter and main contactor to form the infeed/backfeed path.

The Siemens 6SE7090-0XX84-0BJ0 CUSA AFE Control Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
Siemens 6SE7090-0XX84-0BJ0 CUSA AFE Control Module Manuals,Datasheets,Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

Regulation Behavior

  • DC-link control: The CUSA holds the commanded link voltage as line conditions and returned energy change.
  • Bidirectional operation: The same control section manages rectifier and regenerative feedback states.
  • Current waveform: Mains-oriented vector control supports a nearly sinusoidal line current.
  • Command priority: Operating-current demand takes precedence when power-factor and current requests compete.

Required AFE Components

  • AFE inverter: The CUSA commands the voltage-source converter that transfers energy to and from the DC link.
  • Voltage sensing: A VSB board supplies the line-angle reference used by the controller.
  • Line conditioning: The specified reactor and CleanPower filter form part of the mains-side arrangement.
  • Connection path: A supply connecting module and main contactor complete the controlled mains interface.

Control Structure

  • Firmware identity: V2.XX distinguishes the documented CUSA control release.
  • Angle feedback: The FKBL3 signal cable carries VSB line-angle information to the control module.
  • Voltage loop: The controller responds to DC-link deviation instead of relying on open-loop switching.
  • Power-factor request: The command remains adjustable within the available operating-current margin.

Mains Connection Safeguards

  • Electronics supply: An external 24 V DC source powers the AFE control and voltage-sensing electronics.
  • Main contactor: The mains path includes a contactor so the AFE can be isolated by the surrounding control system.
  • Matched reactor: Use the reactor specified for the AFE assembly rather than an arbitrary line inductance.
  • Filter coordination: Confirm the CleanPower filter and supply module are arranged for the selected converter frame.
Description
Siemens 6SE7090-0XX84-0BJ0 is the CUSA control module for SIMOVERT MASTERDRIVES Active Front End infeed and regenerative feedback units. The official product identity specifies firmware V2.XX and positions the board as the control section of the AFE voltage-source converter.

During rectifier and regenerative operation, Siemens 6SE7090-0XX84-0BJ0 regulates the DC-link voltage against changes in line voltage and returned energy. Its mains-angle-oriented vector control commands nearly sinusoidal line current and permits power-factor adjustment while giving operating-current demand priority.

The VSB voltage sensing board supplies line-angle information to Siemens 6SE7090-0XX84-0BJ0 through the FKBL3 signal cable. The surrounding AFE arrangement also requires an external 24 V DC electronics supply and a main contactor in the mains connection path.

Within a complete AFE assembly, Siemens 6SE7090-0XX84-0BJ0 coordinates with the AFE inverter, reactor, supply connecting module and CleanPower filter. These components form the controlled infeed/backfeed path rather than functioning as interchangeable stand-alone boards.

What problem does Siemens 6SE7090-0XX84-0BJ0 solve in an AFE system?
Siemens 6SE7090-0XX84-0BJ0 controls the SIMOVERT MASTERDRIVES AFE converter so the DC link can accept power from the mains or return regenerated energy.
How does Siemens 6SE7090-0XX84-0BJ0 keep the DC-link voltage steady?
Siemens 6SE7090-0XX84-0BJ0 uses mains-angle-oriented vector control to regulate DC-link voltage as line voltage and regenerated energy change.
Which signal path supplies line-angle information to Siemens 6SE7090-0XX84-0BJ0?
The VSB voltage sensing board sends line-angle data to Siemens 6SE7090-0XX84-0BJ0 through the FKBL3 signal cable.
Why does Siemens 6SE7090-0XX84-0BJ0 require an external 24 V DC supply?
Siemens 6SE7090-0XX84-0BJ0 and its VSB electronics use the external 24 V DC supply so control and sensing remain available for the AFE arrangement.
What should be checked if power-factor control on Siemens 6SE7090-0XX84-0BJ0 appears limited?
Siemens 6SE7090-0XX84-0BJ0 gives operating-current demand priority, so verify current loading and commanded power factor before treating the behavior as a fault.
