Product Description:

The 134F2970 is an AC variable-frequency drive built by Danfoss for the VLT FC 360 Automation Drives series. It converts fixed-frequency mains power into adjustable motor voltage and frequency, allowing plant controllers to regulate motor speed without mechanical throttling. The chassis is intended for cabinet mounting and supports compact machines that require consistent torque and modest power output. The drive can be used for applications such as small conveyors, pumps, fans, and other automated equipment that requires controlled acceleration and speed.

It accepts a three-phase input between 380 to 480 VAC and routes the output through a standard control card that manages operating signals and faults. Under rated conditions, the inverter supplies 0.37 kW, which is equivalent to 0.50 HP and is suitable for small pumps or conveyors. The IP20 chassis protection helps prevent accidental contact with live parts but does not seal the enclosure against liquids. To limit conducted emissions, the line filter is rated as RFI Class A2, supporting operation on suitable factory power networks without external chokes. Standard cable entries provide organized routing for power and control wiring inside the cabinet. The keypad area is supplied without a display, so drive status and parameters must be accessed through compatible remote controls or communication tools. A standard language pack provides menu text and parameter descriptions for the control interface.

The dynamic section includes a brake chopper that directs regenerated energy to a suitable braking resistor during rapid deceleration. This function allows the drive to handle frequent speed changes while operating within its electrical and thermal limits. The drive supports the high-overload duty class for short bursts of additional motor torque during demanding starts or load changes. Power sharing across a common DC link is enabled by the load-sharing mains option, allowing multiple FC 360 units to exchange regenerated energy instead of immediately returning it to the supply. This arrangement can reduce the amount of energy dissipated during coordinated acceleration and deceleration cycles. A coated printed circuit board protects internal electronics from dust and moisture carried by cabinet airflow. The coating supports reliable operation in typical industrial environments where airborne contaminants may reach equipment through ventilation openings.
