What Is a 3 Phase Variable Frequency Drive?
A 3 phase variable frequency drive is a power conversion device that rectifies fixed-frequency three-phase AC mains power to DC and then inverts it to variable-voltage,variable-frequency AC output for motor speed control.It regulates the rotational speed and torque of a three-phase induction or permanent magnet motor by adjusting the output frequency and voltage according to a V/Hz or vector control algorithm.
Industrial frequency converters are categorized by control methodology—scalar(V/Hz),open-loop vector,and closed-loop vector—and by power topology,including 6-pulse diode rectifier,active front end(AFE),and 12-pulse configurations.The VACON NXS00055-A2H1SSV-A1A2000000 is a wall-mounted,air-cooled industrial frequency converter employing sensorless vector control with an integrated brake chopper and a 6-pulse diode rectifier front end with internal DC choke.

Technical Highlights
Sensorless vector control delivers high starting torque without encoder feedback.The drive computes motor flux and torque from measured phase currents and DC bus voltage,achieving starting torque greater than 200%of rated torque with steady-state speed error below 1%of rated speed.
Integrated DC choke reduces harmonic distortion at the mains interface.The internal choke within the 6-pulse rectifier topology lowers line-side total harmonic current distortion(THDi)and extends DC link capacitor life by smoothing ripple current.
Integrated brake chopper enables dynamic braking on a single transistor channel.The built-in chopper supports external brake resistor connection for applications requiring controlled deceleration of high-inertia loads.The DC brake function provides up to 30%of rated motor torque without an external resistor.
Expandable I/O and fieldbus architecture supports five option board slots.The drive includes two basic I/O boards(Slots A and B)and three open option slots(C,D,E).Supported fieldbus protocols include Profibus DP,CANopen,DeviceNet,Modbus RTU,and Modbus/TCP,enabling integration into all major factory automation networks.
Applications
Pump control in water and wastewater systems:Provides variable-speed regulation for centrifugal pumps.The integrated PID controller and pump-fan-control(PFC)function for 1–5 pumps reduce energy consumption by up to 50%compared to fixed-speed throttle control at part-load conditions.
HVAC fan and blower management:Drives supply and return fans,cooling tower fans,and exhaust blowers.The drive’s I/O configuration supports temperature and pressure feedback for closed-loop building automation.Low audible noise from high switching frequency(up to 16 kHz)suits occupied spaces.
Conveyor systems for material handling:Controls belt speed for accumulation,indexing,and merge functions.The sensorless vector mode maintains constant torque at low speeds down to 5%of base speed,supporting precise positioning without shaft encoders.
Mixer and agitator drives in process industries:Powers constant-torque mixing applications.The high starting torque capability(over 200%)overcomes the breakaway friction of settled slurries and viscous media without motor oversizing.
Machine tool spindle and feed axis drives:Supplies variable-speed output for lathes,milling machines,and grinding spindles.The 0–320 Hz output range extends beyond standard 50/60 Hz motor ratings for high-speed machining operations.
Crane and hoist traverse/trolley motion:Operates cross-traverse and long-travel motors.The integrated brake chopper manages overhauling load energy during lowering,eliminating the need for an external braking unit.
Selection Guidance
Suitable applications:
Squirrel-cage induction motors up to 2.2 kW(LO)or 1.5 kW(HO)on 380–500 VAC three-phase supplies,requiring standard sensorless vector performance and an IP21 enclosure suitable for indoor control panels
Variable-torque pump and fan loads benefiting from the built-in PID controller and multi-pump function(up to 5 pumps)without external PLC intervention
High-inertia loads such as centrifuges,large-diameter fans,and flywheel-based machinery where the integrated brake chopper supports external resistor connection for controlled dynamic braking
System architectures requiring fieldbus connectivity—the three open expansion slots accommodate Profibus DP,CANopen,DeviceNet,Modbus RTU,or Modbus/TCP option boards
Not recommended for:
Motors requiring a rated current that exceeds the drive's 5.6 A(LO)or 4.3 A(HO)limit.Select the NXS00075-A2H1SSV(7.6 A LO,3 kW)or larger frame size.
Single-phase mains supplies.This drive requires 380–500 VAC three-phase input.For single-phase 230 VAC mains,use drives from the VACON 20 or VACON 100 series.
Applications requiring IP54/NEMA 12 dust and spray protection.Select the NXS00055-A5H1SSS-A1A2000000,which provides identical electrical ratings in an IP54 enclosure.
690 VAC supply networks.The 500 V voltage class is rated for 380–500 VAC.For 525–690 VAC mains,use models coded with voltage class"6"in the model designation(e.g.,NXS00055-A2L0SSV).
