Product Description:

The FC-051PK75TE20H3XXCXXXSXXX is an AC variable frequency drive manufactured by Danfoss for the VLT FC 51 Micro Drives series. It takes constant-frequency mains power and produces variable output voltage and frequency, allowing automation controllers to regulate squirrel-cage induction motors in compact machinery. By matching motor speed to real-time load conditions, the unit supports precise conveyor pacing, pump flow adjustment, and small fan control. Its compact format also conserves space in crowded control panels where larger drives may be difficult to install.

This model accepts a three-phase supply, so it can be wired directly to standard industrial power distribution without single-phase derating. Its continuous motor output is rated at 0.75 kW, which corresponds to 1.0 HP and suits auxiliary axes and other low-power applications. Cabling enters through standard cable entries, simplifying gland plate design because proprietary knockouts are not required. Regenerative energy produced during deceleration is not dissipated internally because the drive has no brake chopper. An external braking resistor cannot be connected directly to the unit, so rapid stopping must be managed through the motor, adjusted deceleration ramps, or a mechanical brake when required. The variable-frequency output provides controlled acceleration and deceleration, which can reduce mechanical stress on belts, couplings, and driven equipment.

The model code includes 051, associating the unit with the parameter menus and control functions used by the micro-drive platform. The unit has no mains option, so harmonic mitigation or supplemental RFI filtering must be installed separately when site requirements call for those functions. Its compact housing and thermal design support installation with reduced panel depth and limited airflow clearance. Built-in control algorithms regulate motor speed according to commands from automation equipment, while application macros simplify setup for common pumps, fans, and conveyors. Parameter copying utilities also allow saved operating values to be transferred between compatible units without manually entering each setting.
