18.5kW(HD)/22kW(ND) 415V VFD – Control & Motor Compatibility
The XD4000-46P3-4C2221 supports open-loop V/F control (5-point), slip compensation and Sensorless Vector Control (SVC), plus closed-loop vector control with encoder feedback for asynchronous motors, and native control laws for permanent magnet (PM) and reluctance motors. It delivers 150% overload (Heavy Duty) / 120% overload (Normal Duty) of rated current for 1 minute, an output frequency range of 0.1–599 Hz, and efficiency up to 98.6% at full load — 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, the XD4000-46P3-4C2221 provides dedicated brake control with brake feedback and separate brake-release current settings for hoisting and lowering, high-speed hoisting (adapting motor speed to load so an empty hook can travel faster), rope slack detection, external load measurement via a weight sensor, dynamic load / load-variation detection, open- and closed-loop torque control for winder applications, and positioning by limit switches or sensors — with a built-in braking transistor standard up to 160kW HD.
18.5kW(HD)/22kW(ND) 415V VFD – Pump, PID & Oil-Field Features
For pumping and process applications the drive includes a built-in PID controller with 4 preset references, sleep/wake-up and sleep-boost modes, and pre-PID predictive frequency. The ENA (Energy Adaptation) / Sucker-Rod function supports progressive cavity pumps (PCP) in oil & gas duty, allowing operation without a braking resistor while reducing mechanical stress and energy use, complemented by Backspin Control for PCP pumps. 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 XD4000-46P3-4C2221 drive can coordinate up to 10 slave drives via MultiDriveLink for 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, wired in 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), with optional PROFIBUS-DP, PROFINET, DeviceNet, CANopen, EtherCAT and POWERLINK cards, all managed from the advanced 8-line, IP65, 2-colour graphical LCD keypad.
18.5kW(HD)/22kW(ND) 415V VFD – Applications
The XD4000-46P3-4C2221 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, and other applications across water & wastewater, chemical & petrochemical, food & beverage, building/HVAC, metal & mining, paper and OEM segments.
