This series of variable frequency drives is designed for general-purpose speed and torque control of three-phase induction motors and selected permanent magnet synchronous motors. Built on a proven and stable control platform, the inverter offers reliable operation and flexible parameter configuration, meeting the basic requirements of industrial motor speed regulation, soft starting, and operational protection.
Control Performance
- Supports V/F control for standard loads and multi-motor applications
- Provides sensorless vector control with stable torque output in low and medium speed ranges
- Adjustable acceleration and deceleration curves for different load inertias
- Smooth frequency output helps reduce mechanical stress
Functional Features
- Multiple frequency setting methods: keypad, analog input, and communication
- Multi-speed operation for process control
- Built-in PID function for constant pressure or flow applications
- Programmable I/O terminals for flexible system integration
- Parameter backup and restore for easier maintenance and replacement
