Product Description:
The VLT 2900 by Danfoss is a reliable and efficient industrial drive. It is designed to handle a wide range of industrial applications with precision and safety. The drive offers outstanding functionalities for various power requirements. This model is part of the VLT 2900 Industrial Drives series.
The VLT 2900 series is available in multiple configurations, providing flexibility to suit diverse needs. It supports mains supply voltages from 380 to 415 V with a frequency range of 0.2 to 132 Hz. This drive ensures a true power factor of 0.90 and a displacement power factor of more than 0.98. In some configurations, the output frequency can be extended up to 1000 Hz. The unit is air-cooled and it requires a minimum air passage of 100 mm for proper cooling. With a wide temperature range of 0°C to 45°C the VLT 2900 may operate successfully up to 55°C with derating. Additionally, it provides precise speed control with an accuracy of ±23 rpm in open loop and ±7.5 rpm in closed loop. The efficiency of the unit ranges from 96% to 97% which depends on the model. It operates with a rated output current of 1.7 A for smaller models and up to 18.5 kg in weight. The unit also supports an overload torque of 160% for both constant and variable torque applications that makes it appropriate for a wide range of operational requirements.
In the VLT 2900 series, if the interior temperature surpasses 100°C, the unit will shut off automatically. It also provides protection against phase loss and intermediate circuit voltage. It may be fine-tuned for specific applications by adjusting parameters such as motor power, current restrictions and braking functions. This drive offers exceptional reliability and performance across multiple applications.
Frequently Asked Questions about VLT 2900:
Q: What does the overload protection in the VLT 2900 help with?
A: The overload protection ensures the motor is safeguarded against excessive load. It helps prevent motor damage and extends its lifespan.
Q: How does the VLT 2900 handle phase loss protection?
A: Phase loss protection in the VLT 2900 immediately cuts off the drive if a phase is missing. This feature prevents potential motor damage from unstable power supply conditions.
Q: Why does the VLT 2900 require a 100 mm air passage for cooling?
A: The VLT 2900 needs proper airflow for effective cooling. It ensures the unit maintains optimal operating temperatures and prevents overheating during continuous operation.
Q: How does the wobble function in the VLT 2900 improve application control?
A: The wobble function in the VLT 2900 helps control the traverse velocity of synthetic yarn winding. It enables precise back-and-forth motion with adjustable parameters for better accuracy.
Q: What is the significance of the 160% overload torque in the VLT 2900?
A: The 160% overload torque provides extra power during high-demand applications. It ensures the drive can handle sudden spikes in load without compromising performance.
