Siemens 6SE7031-6EB87-2DA0 ControlLinks actuator

Product Detailed Description:

The Siemens 6SE7031-6EB87-2DA0 is an SIMOVERT MASTERDRIVES MV converter module. This is a key component within the well-known Masterdrives MV series of medium-voltage converters developed by Siemens. It is designed for the frequency control (variable speed drive - VSD) of squirrel-cage induction motors in medium-voltage applications.

The “MV” in the name signifies its application range, typically for voltages up to 6 kV (and specific models up to 10 kV) and powers ranging from tens to several hundred kilowatts. The module itself likely represents a specific functional unit within the converter system, such as an output module (feeding the motor) or potentially an input module (receiving power from the grid), depending on the exact suffix and configuration. These converters utilize IGBT (Insulated Gate Bipolar Transistor) technology for efficient power conversion and advanced control algorithms for precise motor speed and torque regulation.

Product Parameters:

• Product Type: SIMOVERT MASTERDRIVES MV Converter Module

• Voltage Class: Medium Voltage (Typically up to 6 kV, check specific datasheet for exact rating)

• Cooling: Forced Air Cooling (requires a cooling unit)

• Control Method: Vector Control (for high dynamic performance)

• Protection Classes: Varies by module and enclosure, typically IP23 or higher depending on installation.

• Communication: Often includes options for PROFIBUS DP, PROFINET IO, or other industrial networks (specific capabilities depend on the configuration and additional options).

• Power Range: Depends on the overall converter system configuration (kW or kVA).

• Frequency Range: Adjustable, typically 0 to 400 Hz or higher, depending on motor and application.

• Module Function: Likely an Output Module (6SE7 031…) designed to connect to the motor terminals. Specific parameters like current rating, voltage level, and cooling fan details are critical and found in the datasheet.

(Note: Exact electrical parameters like nominal current, voltage level, power rating, and specific dimensions require consulting the official Siemens datasheet for this exact part number.)

Product Advantages:

1. High Power and Voltage Capability: Designed for demanding medium-voltage applications where standard low-voltage drives are insufficient.

2. Robust Construction: Built to withstand harsh industrial environments, often with high mechanical and thermal stability.

3. Advanced Control Performance: Utilizes vector control for precise speed and torque control, enabling high dynamic response and accurate positioning if required.

4. Flexibility and Modularity: The Masterdrives MV system is modular, allowing for flexible configuration and scalability to meet specific application needs.

5. Wide Range of Functions: Offers numerous integrated functions (e.g., braking, overload protection, diagnostics) and options for customization.

6. Proven Reliability: Siemens Masterdrives are a long-standing and widely used product family known for their reliability in industrial applications.

7. Integration: Seamless integration into Siemens’ automation landscape, particularly with PLCs and other devices using PROFIBUS or PROFINET.

Precautions / Important Notes:

1. High Voltage Risk: These are medium-voltage devices. Extreme caution must be exercised during installation, commissioning, operation, and maintenance. Only qualified personnel should work on these systems.

2. Proper Installation: Requires careful attention to earthing, cable routing (especially for EMC), and thermal management (adequate cooling airflow).

3. Harmonics: Medium-voltage converters can generate harmonics that may affect other equipment on the power system. Consideration of harmonic filters might be necessary.

4. Commissioning: Requires specialized knowledge for parameterization and commissioning to ensure safe and efficient operation.

5. Cooling: Reliable operation depends on the proper functioning of the cooling system (fans, heat exchangers). Regular maintenance is essential.

6. Documentation: Always refer to the official Siemens documentation (manuals, datasheets, application guides) specific to this part number for detailed installation, operation, and safety instructions.

7. Component Specificity: This is a module within a larger system. Its function and connection depend on the overall converter rack configuration.
