Product Description:

The 134F3020 is an AC variable frequency drive manufactured by Danfoss for the VLT FC 360 Automation Drives series. The unit converts fixed-frequency input power into regulated voltage and frequency for compatible AC motors. This output allows pumps, fans, and conveyors to operate at commanded speeds across varying process conditions. Adjusting motor speed to actual demand can improve energy use and provide more precise control in automated plants.

The drive delivers a shaft output of 25 HP, corresponding to a continuous electrical rating of 18.5 kW. It accepts a three-phase supply from 380 to 480 VAC, so a step-up transformer is not required on compatible industrial grids. The IP20 chassis enclosure is intended for installation inside a suitable control cabinet where protection against direct finger contact is sufficient. Conducted emissions are reduced by the integral RFI Class A2 filter, supporting operation on general industrial networks without a separate radio-frequency interference filter. Standard cable entries are included through Adaptation A to support routine cabinet wiring. High-overload mode provides 150% torque for short acceleration periods when the connected load requires increased starting or transient torque. The included standard language pack supports common operator-interface languages when parameters and operating data are accessed.

Dynamic stopping is handled by the integrated brake chopper, which allows an external resistor to absorb regenerated energy during rapid deceleration. Circuit boards have a coated PCB finish that protects the electronics from moisture and airborne contaminants in production areas. A control card with PROFINET provides deterministic communication with compatible PLCs and supports network-based access to drive data. The load-sharing mains option connects compatible parallel drives so regenerated energy and DC-bus loading can be distributed across the system. The housing does not include a local display, so parameters can be adjusted through network tools or an optional remote keypad. This arrangement allows the drive to be operated from a centralized control interface when direct access to the cabinet is limited.
