Product features

The Siemens 6SE6420-2UD17-5AA1 is a filterless inverter from the MicroMaster 420 series.

The 6SE6420-2UD17-5AA1 features superior Flux Current Control (FCC) technology, which is one of its main selling advantages. FCC technology enables real-time, exact control of the motor flux and current, resulting in efficient and reliable performance under a variety of load conditions. Compared to typical control methods, the 6SE6420-2UD17-5AA1 inverter with FCC technology can cut motor energy consumption by 10%-20%, resulting in considerable economic benefits for businesses.

The 6SE6420-2UD17-5AA1 inverter has a tiny design measuring only 173mm × 73mm × 149mm (height × width × depth), making it ideal for placement in tight control cabinets. The inverter also has an IP20 protection grade, which effectively prevents dust and foreign objects from entering and ensures the equipment's reliable operation.

The 6SE6420-2UD17-5AA1 inverter can be utilized in a variety of industrial applications, including fans, pumps, compressors, and conveyor belts. For example, in fan applications, using a proper V/f curve can efficiently lower the fan's starting current and running noise, hence increasing its lifespan. In pump applications, it can precisely modulate pump speed based on actual flow and lift needs, resulting in energy-efficient operation.

Precautions

Follow these important tips while utilizing the Siemens 6SE6420-2UD17-5AA1 Drives to achieve peak performance and dependability. First, environmental circumstances are important to this industrial effort. The Siemens 6SE6420-2UD17-5AA1 performs best in temperatures ranging from -10°C to +50°C and requires protection from dust, moisture, and vibration. Avoid exposing it to high humidity or intense sunshine, since these can cause hardware failure. Ensure that the installation area fulfills EMC (electromagnetic compatibility) standards by using shielded connections and correct grounding to reduce interference-especially because this model has a built-in filter and may require external components for compliance.

Power supply is another important consideration. Use a 380-480V AC power supply with short-circuit protection to ensure continuous energy delivery. Check the power module's capacity, as the drive has a 150% overload capability for 60 seconds. Incorrect wiring, such as reversed phase connections, might harm internal components. To avoid electrical problems and improve system safety, ensure that the PE (protected earth) connector on the power supply is properly grounded.

Compatibility issues can emerge between software and hardware. To ensure full support for the drive's functionality, always program and configure it using the STARTER software. Check for I/O address conflicts in the hardware setup, as undefined addresses can cause issues. When adding modules, make sure they are mentioned in the Siemens compatibility matrix to avoid communication issues. The drive supports protocols such as PROFIBUS and Modbus RTU, allowing for simple interaction with automation systems.

Maintenance is critical to the Siemens 6SE6420-2UD17-5AA1's lifetime. Dust can build and cause overheating, so clean the drive and modules on a regular basis with compressed air. Inspect all connections for looseness, particularly the backplane bus connectors, which can shake loose over time and interrupt data transfer. To avoid data loss, make sure the memory card is securely placed and that the application is backed up on a regular basis. For models with a battery, replace it before the BATF (battery failure) LED illuminates-preferably while the drive is turned on to avoid memory loss.

By following these instructions, users can increase the Siemens 6SE6420-2UD17-5AA1's longevity, efficiency, and interoperability with industrial automation systems. Regular maintenance, proper installation, and proactive troubleshooting will help to reduce costly downtime and guarantee the drive runs well in a variety of industrial situations.

FAQ

Q: Will the filterless design of the Siemens 6SE6420-2UD17-5AA1 lead to electromagnetic interference (EMC issues)?

A: The 6SE6420-2UD17-5AA1 inverter, with its filterless design, may lead to electromagnetic interference (EMC) issues.

Q: Is the 150% overload for 60 seconds suitable for frequently starting and stopping conveyor belt applications?

A: The 150% overload for 60 seconds is suited for conveyor belt applications that require frequent starting and stopping. The conveyor belt frequently experiences short-term overload when beginning and stopping because it must overcome high static friction and the system's inertia. The ability to handle a 150% overload for 60 seconds allows for excellent management of huge loads throughout these start and stop procedures, ensuring that the conveyor belt starts and stops smoothly while preventing overload damage to the motor or inverter.

Q: Is derating required when operating at 55°C in a high-temperature workshop?

A: When working at 55°C in a high-temperature workshop, the Siemens 6SE6420-2UD17-5AA1 inverter should normally be derated. For ambient temperatures ranging from +40°C to +50°C, the rated output current must be reduced by 1% for each 1°C increase. When the ambient temperature reaches 55°C, the maximum output current may be lowered to approximately 85% of its rated value.
