SIEMENS 6ES7193-6AR00-0AA0 REV H Digital Qutput Termination

Product Detailed Description:

The Siemens SIMOVERT MASTERDRIVES MV is a high-performance medium-voltage (MV) converter system designed for the precise and efficient speed control of squirrel-cage induction motors. It is part of Siemens’ renowned Masterdrives family, known for its reliability and flexibility in industrial drive applications.

The MV system typically consists of several modules, including the main converter (rectifier and inverter) modules, which are the core components responsible for converting the fixed-frequency medium-voltage AC supply into a variable-frequency, variable-voltage AC output suitable for controlling the motor speed. These modules often utilize Insulated Gate Bipolar Transistors (IGBTs) for efficient power conversion.

The system is designed for voltages typically ranging from 2.3 kV up to 10 kV and powers spanning several hundred kilowatts to several megawatts. It offers various control strategies, including scalar control (V/f) and vector control (field-oriented control), enabling high dynamic performance and precise torque control.

Product Parameters:

• Voltage Range: Typically 2.3 kV, 3.3 kV, 4.16 kV, 6 kV, up to 10 kV (depending on specific module configuration).

• Power Range: Covers a wide spectrum, typically from several hundred kW up to several MW.

• Frequency Range: Output frequency adjustable from near 0 Hz up to several hundred Hz (depending on application and motor).

• Control Methods: Scalar (V/f), Vector (Field-Oriented Control - FOC).

• Cooling: Typically forced air cooling using fans (often redundant for high availability).

• Enclosure: Usually designed for indoor installation, often IP54 or similar protection rating.

• Communication Interfaces: Integrated interfaces for connection to higher-level control systems (e.g., PROFIBUS DP, PROFINET IO, optional others like Modbus).

• Input/Output Terminals: Configured for the specific medium-voltage level and power rating.

• Harmonic Filtering: Often available as an option or standard feature to meet grid connection requirements.

• Redundancy Options: Available for critical applications, such as redundant power modules or fans.

(Note: Specific parameter values like exact power ratings, current ratings, efficiency figures, etc., depend heavily on the exact module type and configuration within the MV system. Always refer to the specific datasheet.)

Product Advantages:

1. High Power Range: Capable of driving very large motors used in heavy industry.

2. Precise Speed and Torque Control: Especially with vector control, enabling smooth operation and accurate process control.

3. Energy Efficiency: Modern IGBT technology and efficient design contribute to lower energy consumption compared to older technologies or fixed-speed operation.

4. Reduced Mechanical Stress: Soft starting and stopping minimize stress on the motor, mechanical components, and the driven equipment, extending equipment life.

5. Process Optimization: Allows operation at optimal speeds for specific process requirements, improving product quality and throughput.

6. Space Saving: Can sometimes replace complex mechanical speed reduction systems.

7. Flexibility: Adaptable to various control strategies and communication protocols.

8. Reliability: Proven technology with a long track record in demanding industrial environments.

9. Reduced Line Current Harmonics: Often incorporates active front-end technology or harmonic filters.

10. Redundancy Options: Enhances system availability for critical processes.

Precautions / Important Notes:

1. High Voltage: These are medium-voltage devices. Strict adherence to high-voltage safety procedures is mandatory during installation, maintenance, and operation. Only qualified personnel should work on or near the equipment.

2. Professional Installation: Requires specialized knowledge for electrical connections, earthing, and integration into the plant’s power system.

3. Cooling System: Ensure the cooling system (fans) is clean and functioning correctly. Blocked cooling can lead to overheating and failure.

4. Harmonics: Be aware of potential harmonic currents injected into the power grid. Ensure the system design complies with local grid codes, potentially requiring harmonic filters.

5. Proper Grounding: Correct and robust grounding is critical for safety and proper operation.

6. Motor Compatibility: Ensure the connected motor is suitable for variable frequency drive operation. Some motors may require specific designs or derating.

7. EMC Considerations: Proper cable routing, shielding, and grounding are essential to minimize electromagnetic interference (EMI).

8. Software/Configuration: Correct parameterization and software configuration are crucial for safe and optimal operation. Use only Siemens-approved software and tools.

9. Maintenance: Follow the manufacturer’s recommended maintenance schedule, including inspections and potential replacement of wear items like cooling fans.

10. Documentation: Always have the latest version of the operating and maintenance manual readily available.
