◆Applicable to the occasions of large starting resistance, rapid acceleration and deceleration, crane, mud machine, mixer, gantry planer, injection molding machine, extruder and other loads.

SC-600-3R7T2 powerful features:

--Protection of mechanical torque***
◆SC600 inverter can ***torque ***, when the torque exceeds the *** torque that the machine can withstand, the inverter can set the torque *** within the set *** torque Better protect equipment safety under the premise of mechanical efficiency;
◆Reliable torque *** (torque *** value 150%) is suitable for loads such as cranes and extruders.

-- Instant stop
◆This function will only stop the inverter when the power is cut off in an instant. In the case of instantaneous power failure or sudden voltage drop, the inverter reduces the output speed, and the voltage is reduced by the load *** energy to maintain the inverter for a short time. continue working;
◆Applicable to chemical fiber, textile production and other loads.

-- fast current limiting function
◆The fast current limiting function can avoid frequent overcurrent of the inverter. When the current exceeds the current protection point, the fast current limiting function can quickly *** the current in the current protection point, thus protecting the safety of the equipment and avoiding Overcurrent caused by sudden load or interference***.

--Speed tracking function
◆Automatic patented speed tracking algorithm; fast and smooth, zero impact *** motor *** rotation speed, only used for high inertia centrifuges, induced draft fans, electric vehicles and other occasions.
