Product Description:

The 178B2377 is a Decentral Drive from the FCD 300 Micro Drives series by Danfoss. It delivers 0.75kW output in a decentralized control setup that brings variable frequency drive functions right to the motor location. This design removes the need for long motor cables, which can cause voltage drops, electromagnetic interference and complicated installations. The drive enhances distributed automation by allowing precise motor control at remote locations. It is engineered to offer full communication and control through its integrated Profibus DP interface, which works at high-speed 12 MB data rates. This decentralized method cuts installation costs and reduces system complexity by shortening electrical connections and providing localized control intelligence. This makes the drive an excellent fit for modern manufacturing systems that need flexible and scalable automation solutions.

The 178B2377 excels in environmental durability due to its robust construction. Its IP66 enclosure protection and specially coated design help it withstand harsh industrial conditions. This allows it to be installed in tough spots that were once unsuitable for electronic drives, broadening automation possibilities for a wide range of applications. With a weight of just 6.8kg, the drive can be mounted directly on machinery, conveyor systems, or in distributed control cabinets. This is important when space and environmental conditions would prevent traditional centralized drive installations.

The 178B2377 also features excellent electromagnetic compatibility. Its electric noise filter meets EN 55011 Class A1 standards. This strong EMC performance means there’s no need for extra filtering components while complying with strict industrial electromagnetic interference rules. The drive's high-speed Profibus DP communication capability allows real-time integration with control systems for complete process automation and monitoring. This makes the drive perfect for applications needing distributed motor control with centralized monitoring and coordination.
