Product Description:

The 134H0484 is a decentralized AC motor drive produced by Danfoss for the VLT FCD 302 Decentral Drives series. Mounted close to the motor, it provides localized speed control for distributed automation layouts. This placement reduces the length of shielded motor cable runs back to a central cabinet and helps simplify routing along conveyors and transfer sections. The distributed layout also keeps the drive electronics near the point of use, which is useful in material-handling systems where the drive must fit near the machine rather than inside a large enclosure.

This model supplies a motor shaft output of 4.0 HP, while the inverter section is rated for 380-480 VAC three-phase operation that matches common low-voltage industrial AC supplies. Internally, the power section is designed for a continuous output of 3.0 kW, which aligns with the horsepower rating under typical motor efficiencies. Communication to higher-level PLCs occurs through the integrated Profinet interface, permitting cyclic setpoint exchange, status monitoring, and diagnostic queries without add-on cards. The unit uses a standard black IP66/NEMA 4X enclosure, which blocks dust ingress and high-pressure washdown water so it can be mounted directly on machine frames. Conducted emissions are attenuated by the built-in RFI Class A1/C2 filter, helping limit radio-frequency interference in industrial installations.

The mechanical interface relies on metric threads for cable glands and fasteners, simplifying integration in regions where ISO hardware is standard. Parameters can be accessed through the front connector, identified in the options list as a display connector, for use with a handheld keypad during setup and local adjustment. The drive is delivered in a complete large stand-alone configuration, so no additional option boards, mains plugs, or motor connectors need to be fitted before operation. This arrangement supports decentralized installation where a sealed, field-mounted unit is preferred over a cabinet-based drive and where minimal auxiliary hardware is desired.
