Features 1、Better Control: PID control unit enables fast operation speed, short response time, and can quickly get to the equilibrium value for torsion control. Also support online switching of torsion and speed control as well as up to 16 speed running and 4 stage acceleration setting by control terminals. 2、High in Safety: Wide voltage design, the input voltage range is 320V‑460V, which can prevent influence of voltage fluctuations during use, ensuring normal start up, stable and reliable. The current sampling mechanism will enhance the protection of the inverter and peripheral equipment for safety. 3、Other Function: 7 frequency sources, including keyboard setting, analog voltage setting, analog current setting, multi speed running setting, PID control setting, remote communication setting, keyboard encoder. And has V F control, non inductive vector control, switching flux vector control, open loop torsion control, PG vector control and other control methods. 4、Simple Setting: With automatic torsion boost function for 1Hz low frequency large output torsion control under V F control mode, and the torsion response time is less than 40 microseconds. Just select the type according to motor to for quick G type and P type load adjustment, and it will automatically set the most suitable parameters. 5、Practical Uses: Adjust the output voltage by automatically detecting the load current, and perform the maximum efficiency control, the high efficiency operation of the vector control and V F control, not only the fan, the water pump, but also the ordinary machinery can play an outstanding energy saving effect.
