Siemens 6SE7090-0XX84-0AH2 T300 Technology Board for MASTERDRIVES
Product Overview
The Siemens 6SE7090-0XX84-0AH2 is a T300 technology board for the SIMOVERT MASTERDRIVES series of AC and DC drives. This option module plugs into the drive’s option slot and extends its capabilities with advanced closed-loop position control, multi-axis synchronization, PID control, and winding/ unwinding functions. The T300 board enables the MASTERDRIVES to perform complex motion tasks without an external motion controller, reducing system cost and complexity.

Function Library: Position control (point-to-point), electronic cam, winding block, PID, math functions
Advanced Motion and Process Control
The T300 board offloads the drive’s main CPU by handling high-level motion tasks in real time. It can manage a master-slave position following with electronic gearing, electronic cam profiles (for flying shears, rotary cutters), and precise positioning via encoder feedback. Internal PID loops can control pressure, flow, or tension using analog inputs. The board also includes built-in winding and unwinding algorithms (constant tension or constant taper) for film, wire, or textile processing.
Integration with Drive and PLC
The T300 board is mounted inside the MASTERDRIVES unit and communicates with the drive’s internal bus. It can receive setpoints from a PLC via PROFIBUS DP (through the drive’s CBP2 or CBE20 communication board) and send status back. Alternatively, the T300 can be programmed directly using Siemens’ DDS (Drive Development Studio) software or the DriveMonitor tool, creating custom closed-loop sequences that run independent of the PLC.
Programming and Parameterization
Configuration is done using the BICO (Binector Connector) technology of MASTERDRIVES. Users interconnect function blocks within the T300’s library using a graphical interface. The board can store up to 64 motion programs, each with multiple steps (position, speed, gear ratio). Real-time trace functions allow monitoring of encoder signals and PID outputs for debugging.
Applications
Flying saws and cut-to-length lines
Rotary knife control for packaging
Winding and unwinding stands (paper, foil, cable)
Positioning axes for material handling
Press feed control
Diagnostic and Status
The T300 board includes an LED status indicator and can generate fault codes that are displayed on the drive’s operator panel. Using PC software, engineers can monitor encoder counts, position deviation, and drive torque in real time.
Conclusion
The Siemens 6SE7090-0XX84-0AH2 T300 technology board transforms a standard MASTERDRIVES into a powerful motion controller. Its flexible function library and direct integration make it an ideal upgrade for complex motion and process applications.
