XD1000 5.5kW Variable Speed Drive – 415V xD1000 Series VFD by Lauritz Knudsen
The Lauritz Knudsen XD1000-16P0-4B2111 is a 5.5kW variable speed drive, a 415V AC Variable Frequency Drive rated 5.50kW (Heavy Duty) / 7.50kW (Normal Duty), part of the xD1000 AC Drive series from Lauritz Knudsen Electrical and Automation. Built on Frame S3, this is now the highest-power model in the xD1000 lineup available from Konica Automation, stepping up from the 4kW(HD)/5.5kW(ND) model while keeping the same compact S3 footprint.

Motor Control Modes
The XD1000-16P0-4B2111 supports multiple control algorithms to suit different load types: V/F Control (2 Point), Pump-optimized U2/F Control, Sensorless Vector Control (SVC), and Slip Compensation for improved speed accuracy under varying load — making it suitable for fans, pumps, conveyors, and general industrial motor control applications.
Built-in Braking Chopper
This model includes an integrated dynamic braking chopper as standard, enabling fast motor deceleration and controlled stopping without the need for an external braking unit — useful in applications requiring quick stops or frequent start/stop cycles.
Forced-Fan Cooling – Frame S3
As a Frame S3 unit, the drive uses forced-fan cooling (1 fan, minimum airflow 50 m³/h) to manage heat dissipation at this higher power rating, maintaining reliable operation with acoustic noise kept to approximately 50 dBA.
Built-in Modbus RTU
Integrated Modbus RTU communication (RJ45 connector, 2-wire RS485, 4800–38400 bps) allows the drive to be connected directly into a PLC or SCADA-based automation network for remote monitoring, parameter configuration, and centralized control — without requiring an external communication module.
Applications
Well suited for HVAC fans and pumps, water supply systems, compressors, conveyor systems, mixers, and general-purpose industrial motor control where a higher-power 415V drive with robust overload capacity is required. As a 5.5kW variable speed drive, it delivers the torque and speed control needed to keep these demanding loads running efficiently.

FAQ
Q: Can this drive be used for pump and fan applications?
A: Yes, the built-in Pump U2/F control mode is specifically designed for variable-torque pump and fan loads.
Q: Does it need an external braking resistor unit?
A: No external chopper unit is required — the braking chopper is built into the drive; an external braking resistor (minimum 28Ω) can be added for higher braking duty if needed.
Q: What communication protocol does it support?
A: Built-in Modbus RTU is standard for integration with PLC/SCADA systems.
