Variateur d'automatisation VLT 75kW Danfoss FC-302P75KT5P55H2XGCXXXSXXXXA4BXCXXXXD0

Product Overview

The FC-302P75KT5P55H2XGCXXXSXXXXA4BXCXXXXD0 (FC-302P75KT5P55H2XGCXXXSXXXXA4BXCXXXXD0) is a high-performance VLT® AutomationDrive FC 302 designed for complex industrial applications requiring precision speed and torque control. This 75 kW (100 hp) advanced version is engineered to manage all asynchronous and permanent magnet motors with exceptional reliability. Built with a modular architecture, this specific unit features an IP55/Type 12 enclosure for protection against dust and water, and is equipped with Class 3C3 conformal coating on all PCBs to ensure durability in corrosive or harsh environments. With integrated DeviceNet connectivity and a 24 VDC backup supply option, the FC-302 serves as the central control hub for heavy-duty operations in mining, marine, and chemical processing industries.

Technical Specifications

Technical FAQs

What is the advantage of the MCB 107 24 VDC Supply Option (D0)?

The D0 suffix indicates the inclusion of the MCB 107 module. This allows the drive’s control logic, fieldbus (DeviceNet), and LCP to remain active even if the 400V mains power is disconnected. This is critical for maintaining communication with the master PLC and performing diagnostics during power outages or maintenance.

How does the 3C3 Conformal Coating protect the drive?

The Class 3C3 coating provides superior resistance against aggressive gases (such as Hydrogen Sulphide, Chlorine, and Ammonia). While standard drives fail due to corrosion on solder joints, the FC-302P75K is specifically built for environments like wastewater treatment or chemical plants where these gases are present.

Does this drive require a separate interface for commissioning?

No. This unit comes with the LCP-102 Graphical Display. It supports multiple languages and provides trending graphs and setup wizards, allowing for full commissioning and troubleshooting without the need for external software, although MCT 10 software can still be used via the USB port.

Engineering & Installation Guide

• IP55 Enclosure Integrity: To maintain the IP55 rating, ensure that all cable glands are correctly sized and tightened. The entry plates must be sealed according to Danfoss specifications to prevent moisture or dust from entering the power section, which is critical for the 75 kW power electronics.

• Thermal Management: Even with an IP55 rating, the drive generates significant heat at full 75 kW load. Ensure sufficient clearance around the drive and verify that the ambient temperature does not exceed 45 deg C without derating. The internal fans must have an unobstructed path for air circulation.

• DeviceNet Termination: When integrating the MCA 104 (A4 option) into a DeviceNet network, ensure that termination resistors (121 ohms) are placed at both ends of the trunk line. Use high-quality thick or thin DeviceNet cable to ensure signal integrity across the 75 kW electromagnetic environment.
