XD3000 0.55kW 415V Three-Phase Variable Frequency Drive | xD3000 Series VFD

XD3000-01P9-4B2121 — 0.55kW Three-Phase Variable Frequency Drive (415V)

The Lauritz Knudsen xD3000 XD3000-01P9-4B2121 is a 0.55kW 415V VFD built for demanding OEM and hoisting applications on a 380–500V (-15/+10%), three-phase, 50/60Hz supply. It combines a compact S2C frame with advanced motor control, built-in EMC filtering, and crane-duty features such as external brake control and load sharing. Explore the complete range in our Lauritz Knudsen variable frequency drives collection.

0.55kW 415V VFD – Motor Control Modes

The xD3000 supports Async Motor V/F control (2-point and 5-point), slip compensation, V/F energy saving with quadratic V/F, and sensorless vector control (SVC). It also drives Permanent Magnet synchronous motors directly. The output frequency range extends to 599Hz, so this 0.55kW 415V VFD suits both standard induction motors and high-speed spindle applications. A motor surge limit function further protects old, poor-quality, or rewound motors.

0.55kW 415V VFD – Hoisting & Crane-Duty Features

Unlike a general-purpose drive, the xD3000 includes dedicated hoisting functions: external brake release/engage control with configurable interlocks for horizontal and vertical movement, high-speed hoisting with rope-slack detection, external load measurement via a weight sensor, torque limitation, traverse control, and load sharing across multiple motors. Kinetic Energy Buffering (KEB) rides through short supply dips without tripping the drive, and five built-in safety functions (STO, SLS, SS1, SMS, GDL with an optional safety card) protect personnel and equipment.

0.55kW 415V VFD – Built-in Modbus RTU & Fieldbus Options

A built-in RJ45 port gives native Modbus RTU and CANopen connectivity, so the XD3000-01P9-4B2121 links directly to a PLC, HMI, or SCADA system. Optional communication cards add Modbus TCP, EtherNet/IP, PROFIBUS-DP, PROFINET, DeviceNet, EtherCAT, and POWERLINK. General-purpose features round out the package: an in-built PID controller with four preset references, Sleep/Wake-Up, Catch-on-the-Fly (flying start), Fire Mode/fault inhibition, current limitation, DC braking, and freewheel/fast stop.

0.55kW 415V VFD – Applications

This 0.55kW 415V VFD is widely used in overhead cranes and hoists, warehouse and material-handling equipment, winding/unwinding and traverse machinery, conveyors, gate barriers, and other OEM equipment that needs precise torque and speed control. Its S2C frame keeps the footprint small inside crowded control panels while still meeting IEC 61800-3 Category C2/C3 EMC requirements with the built-in filter.

Frequently Asked Questions

Is the XD3000-01P9-4B2121 suitable for crane and hoist duty? Yes. It includes dedicated brake control, rope-slack detection, and load-sharing functions built specifically for vertical and horizontal hoisting movement.

Can it control Permanent Magnet (PM) motors? Yes, the xD3000 has a native control law for Permanent Magnet synchronous motors in addition to standard induction motors.

Does it need an external EMC filter? No for most installations — an EMC filter compliant with IEC/EN 61800-3 Category C2/C3 is built in; an external filter is only needed for Category C1 environments.

Summary

In summary, the XD3000-01P9-4B2121 0.55kW 415V VFD pairs a compact S2C footprint with hoist-ready features, native fieldbus connectivity, and a wide 0.5–599Hz frequency range. It is a strong choice for crane, hoist, and general OEM motor-control applications, and it ships fast from Stockhai’s warehouse in India.
