The entire product series supports a common DC bus scheme, reducing power loss in the braking resistor. However, careful calculation of the inrush current and input AC system capacity is necessary.
3000 Series Inverter Overview
The 3000 series is a powerful, high-performance current vector inverter capable of controlling asynchronous and permanent magnet synchronous motors. Building upon the 3000 series technology, it adds PG control, supports various PG cards, supports multi-motor switching, and can be used to drive various automated production equipment in textiles, papermaking, fiber drawing, machine tools, packaging, food processing, and other industries.
3000 Excellent Performance
- Supports Vector Control of Multiple Motors
Supports vector control of three-phase AC asynchronous motors and three-phase AC synchronous motors, and supports vector control of permanent magnet synchronous motors without absolute position feedback. Switching between synchronous and asynchronous motors is possible.
- Supports Multiple Encoders
- New Sensorless Vector Control Performance;
Sensorless vector control allows for stalled operation, outputting 150% of rated torque at 0.5Hz. Sensorless vector control reduces sensitivity to motor parameters, improving field adaptability. It can be applied to winding control, load distribution under multiple motors driving the same load, and other applications.
