FST-900 4 Quadrant Energy Feedback Frequency Inverter
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.
200% torque output at 0 speed
PG vector control and V/F control
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 performance to realized 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
The expansion board can be selected by customer’s request.
Conveyor belt, harbor machinery, mine hoist, pour-into washing machine, pharmaceutical machinery, centrifugal casting machine, centrifuge and metal processing machinery such as large punching machine
