Product Description:

The 131B0468 is an AC variable frequency drive produced by Danfoss for the VLT FC 302 Automation Drives series. Within an industrial automation cell, the unit converts fixed-frequency plant power into a regulated output that allows induction motors to follow programmed speed ramps. This control supports applications that regulate flow, pressure, conveyor movement, or linear travel without relying on mechanical gear changes. By adjusting voltage and frequency according to demand, the drive allows supervisory controllers to match motor torque to the connected load and reduce unnecessary energy consumption. Controlled acceleration and deceleration can also reduce mechanical stress on couplings, belts, bearings, and other driven components.

The inverter has a continuous output capacity of 4.0 kW, corresponding to a motor output of 5.0 HP when operating compatible equipment. The incoming supply uses three-phase power, allowing the rectifier to distribute current across the DC link. For controlled deceleration and emergency stopping, an integrated brake chopper routes regenerated energy to an external braking resistor. This arrangement helps manage energy returned by the motor when a high-inertia load slows more quickly than it would through natural deceleration. A graphical local control panel provides access to operating parameters, alarms, status information, and real-time speed feedback without requiring an additional display. Its visual interface supports direct adjustments at the drive and makes operating conditions easier to review from the front of the enclosure.

Physical installation is simplified by standard cable entries that align with commonly used gland plates and support orderly routing inside the cabinet. The unit has uncoated control electronics, making it appropriate for clean indoor installations or sealed electrical cabinets where moisture, conductive dust, and corrosive vapors are controlled. Adequate enclosure protection should therefore be provided when the surrounding area contains airborne contaminants or condensation. The drive belongs to the VLT AutomationDrive FC product group, which supports use in general industrial motor-control applications. Its enclosure arrangement accommodates power, motor, braking, and control wiring while keeping the connections accessible for installation and routine inspection.
