Technique features
FST-900 four quadrant frequency inverter adopt the latest and most sophisticated control technology, and use the energy regeneration of IGBT DC supply device, so as to finish the bi-directional control of rectifier energy feedback and realize the real four quadrant run.
- Renewable control, can help to save much energy on the use of inertial-load crane application system.
- Controllable unit power factor "1" can help to reduce the harmonic to less than 2%.
- Applicable to monitor operation condition and fault through the keyboard, keep various control variables a second before the fault, such as the input voltage, current, frequency, input power and temperature, so as to follow and refresh the data records.
- Rectifier/feedback unit adopt sine wave to provide renewable electric energy feedback to grid automatically, this is more energy-saving and environmental than the traditional braking unit and braking resistor.
- Excellent closed loop vector control perfomance to realize 200% torque output at zero speed.
- Four speed control modes: no PG vector control, PG vector control, V/F control without PG, V/F control with PG.
