Variateur Danfoss VLT AutomationDrive FC-302P7K5T5E20H2

Product Overview

The FC-302P7K5T5E20H2XXXXXXSXXXXA0BXCXXXXD0 (131B0689) is a high-performance VLT® AutomationDrive FC-302 engineered by Danfoss for advanced industrial motor control. Delivering 7.5 kW (10 HP) of power, this three-phase inverter is optimized for complex automation tasks in sectors such as automotive assembly, high-speed packaging, and chemical processing. The FC-302P7K5T5E20H2 features a specialized hardware configuration including a PROFIBUS DP MCA 101 interface and an MCB-107 24V DC backup module, ensuring seamless integration into high-level fieldbus networks and maintaining control logic during primary power loss. Its rugged A3 frame size and intelligent thermal management significantly reduce heat-related failures, maximizing system uptime in demanding production environments.

Technical Configuration

The VLT® AutomationDrive FC-302 is built on a modular platform designed for maximum flexibility. This specific unit is configured for 380 - 500 VAC mains voltage and housed in an IP20/Chassis enclosure, suitable for installation within protected control cabinets. While this variant utilizes an H2 RFI filter for electromagnetic compatibility, it is designed for standard environments with non-coated PCBs. A critical functional enhancement included in this model is the D Option (MCB-107), which provides 24V DC backup power to the control card, allowing fieldbus communication and encoder positions to remain active even when the 400V mains power is disconnected for safety or maintenance. The A Option (MCA 101) adds high-speed PROFIBUS DP connectivity, enabling real-time diagnostic feedback and precision speed control.

Technical FAQs

How does the MCB-107 24V DC backup benefit the system?

The MCB-107 module allows the drive's control circuit and communication options (like PROFIBUS) to remain powered from an external 24V source. This ensures the PLC does not lose contact with the drive during a mains power cycle, preventing "node failure" alarms and allowing for faster system recovery.

Can this drive be used in high-humidity environments?

This specific configuration features "X" for PCB coating, meaning the boards are not coated. For environments with high humidity or corrosive gases, it is recommended to specify a "C" version (3C3 coating) to ensure long-term reliability of the internal electronics.

What is the maximum cable length supported for the motor?

With the H2 RFI filter in an A3 frame, the FC-302 typically supports up to 150 meters of shielded motor cable or 300 meters of unshielded cable while maintaining performance. However, for strict EMC compliance, always refer to the specific Danfoss installation manual for the A3 frame size.

Engineering & Installation Guide

• Harmonic Mitigation: The FC-302 includes integrated DC link reactors that reduce harmonic distortion to below 40-45% THDi. To further optimize power quality in facilities with many 7.5 kW drives, ensure that the mains supply is balanced and consider an upstream active filter if the total harmonic load exceeds 5% of the transformer capacity.

• Profibus Termination: When wiring the MCA 101 PROFIBUS option, ensure that the physical termination switch is set to "ON" only at the first and last nodes of the network segment. Use high-quality purple PROFIBUS cable and keep signal lines at least 200 mm away from motor power cables to prevent data corruption.

• Mounting & Cooling: The A3 frame requires a minimum of 100 mm clearance above and below the unit for vertical airflow. Since this is an IP20 chassis, ensure the cabinet fan capacity (m3/h) exceeds the total heat dissipation of all drives within the enclosure to prevent thermal tripping during peak 10 HP loads.
