1.Main Functions

• AC frequency and voltage conversion: Converts fixed-frequency 3-phase 380V mains AC power into adjustable-frequency and adjustable-voltage AC output to control AC induction motor speed.
• Stepless speed regulation: Realizes continuous motor speed adjustment to match process flow requirements, replacing traditional mechanical speed regulation.
• Motor soft start: Starts the motor with low starting current, reduces mechanical impact and inrush current to protect motor and power grid.
• Torque control & constant torque output: Provides stable constant torque output suitable for heavy-duty constant torque loads.
• Multiple protection functions: Overcurrent protection, overvoltage protection, undervoltage protection, overload protection, overheat protection, phase loss protection and short-circuit protection.
• Built-in PID closed-loop control: Supports closed-loop regulation for pressure, flow or temperature control by connecting external sensors.
• Communication interface: Supports RS485 serial communication, compatible with Modbus protocol for connection with PLC, DCS and HMI systems.
• Multi-speed operation: Presets multiple fixed speeds for simple logic switching according to production requirements.
• Energy saving: Reduces power consumption for fan and pump loads by lowering motor operating speed.

Core summary: This variable frequency drive converts fixed 380V three-phase AC power into variable-frequency power to drive asynchronous motors. It achieves stepless speed regulation, soft start and energy saving, and supports closed-loop control and communication with automation systems.plcva.com.
