131B0081 Variable Frequency Drive VLT FC302 5.5kW 3-ф/380

131B0081 — VLT FC302 rated 5.5 kW, three-phase 380 V. The top AutomationDrive build — flux-vector, torque at zero, STO for critical and dynamic tasks.

Typical applications:

• A hoist with torque at zero speed
• Winding, a centrifuge or extruder with torque control
• A dynamic machine-tool or robot drive

Note: three-phase 380 V model on the AutomationDrive platform. At this power Danfoss offers several builds (EMC filter class, IP rating, LCP panel, board coating, mains-disconnect option). Before ordering, check it against order code 131B0081 so the build matches your cabinet — ask us if unsure.

Danfoss VLT AutomationDrive FC302 — the top drive for dynamics and high power

The FC302 is the AutomationDrive flagship: encoder flux-vector control, full torque at zero speed, precise positioning and axis synchronisation. It is chosen where the FC301 can no longer keep up dynamically, or where power up to 500 kW is needed. This is our widest Danfoss range: 0.7–500 kW, all three-phase 380 V. Hoists, centrifuges, winders, large extruders, test rigs — that is its work.

What the FC302 is good for

• Hoisting gear and cranes (5.5–90 kW): torque at zero holds the load, controlled brake operation.
• Winding, centrifuges, extrusion (11–160 kW): precise torque and tension control.
• Large pumps, compressors, mains machinery (160–500 kW): where the FC301 is no longer built.

What the FC302 adds over the FC301

The key is closed-loop control. In encoder flux-vector mode the FC302 holds set torque from zero speed — critical for hoists and winders. Built-in Safe Torque Off (STO) simplifies the emergency-stop circuit without external contactors. Dynamic braking with the built-in chopper absorbs the inertia of a centrifuge or flywheel. Communication is Modbus RTU on board, with optional PROFIBUS, PROFINET, EtherCAT and EtherNet/IP via MCA cards. This is a drive built to integrate into serious automation.

For a static task the FC302 is overkill and costs more than an FC301. But for dynamics, positioning and power above 75 kW there is no alternative in the range.

When the FC302 is NOT the right choice

• A simple constant-torque conveyor or pump — you overpay; choose the FC301.
• A water-utility pump with dedicated functions — the FC202 AQUA series fits better.
• Small machinery up to 22 kW with no dynamics — an iC2 is enough.

Our experience with the FC302

Customers choose the FC302 for critical jobs — hoists, winding, large drives from 90 kW, where the cost of an error is high. Sizing to the load profile and picking the right communication options matter here, so we recommend confirming the configuration with our engineer before ordering. We can also advise on the motor for flux-vector control. The full Danfoss range is on the brand page.
