Product Description:

The decentralized frequency inverter 134G0021 is produced by Danfoss for the VLT FCD 302 Decentral Drives series. Mounted close to the motor, the unit regulates speed and torque in conveyor sections, mixers, and other field-installed machinery, eliminating long motor cable runs and reducing panel heat load in distributed automation. Its decentralized layout allows the drive to be installed near the driven equipment instead of inside a main control cabinet. The unit is a complete small stand-alone package, and it has a dedicated display connector for local parameter cloning.

The drive accepts a three-phase input of 380–480 VAC, and its inverter section is rated for 0.75 kW or 1.0 HP mechanical output. A sealed black housing carries an IP66/NEMA4X rating, so washdown and outdoor locations are allowed without added enclosures. Conducted emissions are limited by the integrated RFI Class A1/C2 filter. Communication is handled through the A option, which uses the fieldbus interface Profibus DP; no B or D options are installed. The unit is supplied without brackets, without a mechanical brake, and with no internal switch option, so external isolation hardware must be used where required.

Cabling is field-friendly because the enclosure provides the fieldbus connector as an M12 Profibus plug, while mains, motor, and sensor plugs are omitted, so those conductors are hard-wired. Hard-wired power and motor conductors also allow cable entry methods to match site-specific routing needs. All threaded fittings follow metric threads for consistency with European conduit accessories. The design leaves the B option bay empty, the D option bay empty, and the sensor, switch, and mains receptacles empty, making the layout suitable for standard induction motors. The product is cataloged under the VLT Decentral Drive FCD group and carries the series code 302.
