Product Overview
MODBUS VFD980It is a high-performance vector frequency converter, from0.75kWArrived400kWThe entire series is available for selection,380VThree phase input/three-phase output. By adopting advanced sensorless vector control algorithms, the speed and torque of industrial motors such as fans, pumps, and compressors can be accurately controlled. supportSVCCommunication, throughRS485 Modbus RTURemote monitoring of motor operation status, frequency adjustment, and motor start stop to achieve industrial applicationsHome AssistantIntelligent motor control.4.0Vector control technology
Traditional
The frequency converter has low control accuracy and poor low-speed torque.V/FUsing vector control, the motor current is decomposed into excitation component and torque component for independent control, achieving:VFD980Rated torque150%Low speed startup@0.5HzSteady state speed accuracy and fast dynamic response±0.5%Core parameters.

Control start/stop, set frequencyModbusRead operating frequency, current, voltage, temperature, and fault codes. Typical automation: water pressure(0-50Hz)Set value<Speed up of frequency converter→Water pressure restoration→Variable frequency drive deceleration (constant pressure water supply→application scenariosPID).
constant pressure water supply
- closed-loop control of water pump speed to maintain constant pressure in the pipeline network: PIDenergy-saving of fans
- deceleration operation when air volume demand decreases, energy-savingair compressor transformation30-60%
- variable frequency drive replacing power frequency start stop to eliminate current shockpurchase and consultation
