Functionality
Multi-Mode Speed Regulation
Offers flexible speed control through three distinct modes, adapting to the specific requirements of different industrial scenarios. From basic V/F control for simple applications to precise FVC for high-demand tasks, it ensures optimal performance across use cases.
Rapid Torque Response
The DSP control system decouples and regulates magnetic flux current and torque current, enabling quick torque response. This is critical for applications where sudden load changes require immediate adjustment to maintain stability.
Smooth Tracing Start
Features a speed tracing re-start function that achieves non-shock, gentle start-up by tracing the motor’s existing speed. This protects equipment from mechanical stress and ensures smooth operational transitions.
Intelligent Control Functions
Integrates 16-section speed control, simple PLC logic, PID control, and swing frequency control. These built-in functions reduce the need for additional control components, simplifying system design.
