1、Through the built‑in PLC or control terminal to achieve up to 16‑speed operation, linear or S‑curve acceleration and deceleration mode, the range is 0.0‑3600.0s. 2、In case of instantaneous power failure, the voltage is compensated by the load feedback energy to keep the inverter running in a short time. 3、When the VF operating load changes, the output current is automatically limited to prevent over‑current tripping and realize the "shovel" characteristics. 4、With motor short circuit detection, input and output phase loss protection, overcurrent, overvoltage protection, undervoltage, protection, overload protection, etc. 5、The parameters can be quickly copied through the LED operation panel, and part or all of the keys can be locked to prevent misoperation. 6、Digital setting, analog voltage setting, analog current setting, pulse setting, communication setting, can be switched in many ways.
