Allen-Bradley 20F11ND040AA0NNNNN

The Allen-Bradley 20F11ND040AA0NNNNN is an adjustable frequency AC drive that stands as a robust and adaptable solution for industrial applications, offering precise control, reliable performance, and a comprehensive set of features.

Technical Details:

The 20F11ND040AA0NNNNN belongs to the PowerFlex 753 product family, offering compatibility with 3-phase power systems at voltage classes of 400 VAC and 480 VAC. The drive supports a wide input voltage range, ranging from 342 VAC to 440 VAC for the 400 VAC class and 432 VAC to 528 VAC for the 480 VAC class.

For the 400 VAC input, the drive exhibits Normal Duty output ratings of 40 A and 22 kW, with Heavy Duty ratings of 37 A and 18.5 kW. On the other hand, the 460 VAC input results in Normal Duty outputs of 43 A and 30 HP, with Heavy Duty outputs of 51 A and 25 HP. Additionally, a break resistor is included to enhance performance.

Communication Interface:

The 20F11ND040AA0NNNNN supports the installation of communication modules, notably the dual Ethernet communication adapter. This adapter facilitates high-speed communication, supporting both fast Ethernet and gigabit Ethernet, enabling seamless interaction with partner devices.

Furthermore, the 20F11ND040AA0NNNNN incorporates three option slots for connecting I/O, enhancing its flexibility for various applications. The auxiliary control power of the drive ensures continued support in the event of power loss from the main supply.

It features an automatic feedback loss switchover and offers versatile feedback options, including universal, encoder, and dual encoder feedback. This broad range of feedback interfaces supports applications such as Incremental, SSI, BiSS rotary-linear, EnDat, and Hiperface for Stegmann and Heidenhain high-resolution feedback.

Mounting and Installation Instructions:

Begin by selecting an appropriate location for mounting the drive. Ensure the chosen space is well-ventilated and free from excessive dust or moisture. The IP00/IP20 enclosure is designed to provide protection in various industrial environments.

Mount the drive on a stable and secure surface using the provided mounting brackets. Ensure that the mounting surface can withstand the weight of the drive. Connect the power supply to the AC input terminals of the drive. Use proper electrical connections and secure them tightly to prevent loose connections.

Ensure the included break resistor is installed correctly. This resistor plays a crucial role in dissipating heat generated during braking, maintaining optimal performance. If your application requires protection against electromagnetic interference, ensure that EMC filtering options are correctly configured.

Before powering up the drive, double-check the environmental conditions. Ensure that the ambient temperature, humidity, and other relevant factors align with the specified operating conditions for the drive.

Perform a final inspection to ensure all connections are secure and there are no loose components. Verify that the drive is correctly configured for your application requirements.
