SIEMENS 6SE7090-0XX84-0AB0 Regenerative Inverter Module

Product Description:

The 6SE7090-0XX84-0AB0 is a high-performance inverter output module from Siemens' SINAMICS series, designed for precise motor speed control in industrial automation. Below are its key features, technical specifications, and application details:

Technical Specifications:

Features and Advantages:

Energy Efficiency

Regenerative Feedback: Returns braking energy to the grid, reducing heat loss.

Efficient Rectification: Minimizes capacitive reactive current, improving grid stability.

Flexible Control

Vector Control: High dynamic response for precision positioning (e.g., packaging machines, CNC machines).

V/F Control: Simplified commissioning for general-purpose equipment (e.g., fans, pumps).

Comprehensive Protection

Built-in overcurrent, overvoltage, phase-loss, and overload protection for motor and system safety.

Supports integration with external protection devices (e.g., circuit breakers, thermal relays).

Communication Capabilities

Real-time data exchange via PROFIBUS/PROFINET with PLCs or upper-level systems.

Configurable via TIA Portal/STEP 7 software for parameter settings and diagnostics.

Applications

Vertical Loads: Cranes, elevators, conveyors.

High-Inertia Loads: Centrifuges, rolling mills, winding machines.

Frequent Start/Stop: Theater stage equipment, automated storage systems.

Application Examples:

Manufacturing:

Precision conveyor belt speed control (±0.1mm accuracy) for food/pharmaceutical packaging.

Energy Sector:

Stable power transmission in ±800kV UHVDC systems.

Automation Equipment:

Dynamic tool feed speed adjustment in CNC machines, improving milling efficiency by 35%.

Installation and Configuration:

Installation Requirements:

Install in a well-ventilated control cabinet, avoiding dust and humidity.

Separate power and signal cables to prevent electromagnetic interference (EMI).

Commissioning Tools:

Use SINAMICS Drive ES or STARTER software for parameter setup and tuning.

Wiring Example:

U/T1, V/T2, W/T3: 3-phase motor output terminals.

AI1/AO1: Analog input/output terminals (for speed/torque reference).

Notes:

Compatibility Verification:

Ensure communication protocol compatibility with target inverters (e.g., SINAMICS G120) or PLCs.

Firmware Updates:

Regularly check Siemens' official website for firmware upgrades to optimize performance.

Thermal Management:

Clean dust from fans and modules periodically to prevent overheating.
