XD4000-46P3-4C2221 — 18.5kW(HD)/22kW(ND) Three-Phase Variable Frequency Drive (415V)
The Lauritz Knudsen xD4000 XD4000-46P3-4C2221 is a 18.5kW(HD)/22kW(ND) 415V VFD built for crane/hoist duty, pump & PID process control, and general OEM/process automation. Because every xD4000 drive ships with a built-in DC reactor and a built-in EMC filter (C2/C3 compliant), it is part of the flagship Lauritz Knudsen range.

18.5kW(HD)/22kW(ND) 415V VFD – Control & Motor Compatibility
This 18.5kW(HD)/22kW(ND) 415V VFD supports open-loop V/F control (5-point), slip compensation and Sensorless Vector Control (SVC). It also offers closed-loop vector control with encoder feedback for asynchronous motors, plus native control laws for permanent magnet (PM) and reluctance motors.
As a result, it delivers 150% overload (Heavy Duty) or 120% overload (Normal Duty) of rated current for one minute. The output frequency range spans 0.1–599 Hz, and efficiency reaches up to 98.6% at full load — for example, giving reliable torque and speed control across induction, PM and reluctance motor types.
18.5kW(HD)/22kW(ND) 415V VFD – Crane & Hoisting Features
For crane, hoist and material-handling duty, this 18.5kW(HD)/22kW(ND) 415V VFD provides dedicated brake control with brake feedback. It also sets separate brake-release currents for hoisting and lowering.
Because empty hooks travel faster with high-speed hoisting (adapting motor speed to load), operators save cycle time. In addition, rope slack detection, external load measurement via a weight sensor, and dynamic load detection are included. Open- and closed-loop torque control for winder applications, plus positioning by limit switches or sensors, round out the package — a built-in braking transistor is standard up to 160kW HD.
18.5kW(HD)/22kW(ND) 415V VFD – Pump, PID & Oil-Field Features
For pumping and process applications, this 18.5kW(HD)/22kW(ND) 415V VFD includes a built-in PID controller with 4 preset references. It also supports sleep/wake-up and sleep-boost modes, along with pre-PID predictive frequency.
The ENA (Energy Adaptation) / Sucker-Rod function supports progressive cavity pumps (PCP) in oil & gas duty. Therefore, operation is possible without a braking resistor, reducing mechanical stress and energy use; Backspin Control for PCP pumps complements this. Feedback monitoring covers pipe break, fire-hydrant-opened, mechanical breakdown and water-leakage conditions, and pump cycle monitoring tracks start counts to avoid unwanted aging.
18.5kW(HD)/22kW(ND) 415V VFD – Master-Slave, MultiDriveLink & Connectivity
Using the onboard Ethernet port, one master 18.5kW(HD)/22kW(ND) 415V VFD can coordinate up to 10 slave drives via MultiDriveLink. This enables speed synchronisation or torque/load sharing in common-shaft applications such as dual-motor kilns, tandem or grab cranes, long belt conveyors and parallel-chain textile stenters.
Wiring is flexible — daisy-chain, star or redundant-ring (RSTP) topology over standard Ethernet cabling. Communication is built-in via Modbus RTU / Modbus TCP / Ethernet IP (1 RJ45 port for Modbus plus 2 RJ45 ports for Modbus TCP/Ethernet IP). Optional PROFIBUS-DP, PROFINET, DeviceNet, CANopen, EtherCAT and POWERLINK cards are available, all managed from the advanced 8-line, IP65, 2-colour graphical LCD keypad.
18.5kW(HD)/22kW(ND) 415V VFD – Applications
This 18.5kW(HD)/22kW(ND) 415V VFD is well suited to chemical & petrochemical conveyors, overhead cranes, sucker rod (PCP) oil pumps, distillery ID/SA fans, sponge iron DRI ID fans, cold storage screw compressors, paper mill pumps, and wire drawing winders. In short, it fits water & wastewater, chemical & petrochemical, food & beverage, building/HVAC, metal & mining, paper and OEM segments.
