Introduction
As for the vector universal converter, the DSP control system is used to complete optimized speed sensorless vector control, V/F control and torque control, with more optimized function, more flexible application and more stable performance.
It can be widely used for plastic film blowing machines, fan, pump load and applications with high requirements for speed control, torque response speed and low frequency output characteristics.
Our company continues to pursue product quality, strictly screen the original products, pay attention to each production process, and wholeheartedly manufacture each product.

Three control methods: No PG vector control (SVc), VIF control and torque control Starting torque: No PG vector control (SvC): 05Hz/150% rated torque;
0.75~18.5kW specification built-in brake unit. If the quick parking is required, the brake resistance can be directly connected; 16-segment simple PLC, multi-speed control and PID control;
Supporting a variety of frequency settings: Digital setting, analog setting, PID setting, communication setting, etc. Support start and stop DC braking;
Input and output terminals are freely programmed. Users can combine a variety of working modes as per their needs; There is a hopping frequency control function, with mechanical resonance avoided to make the system more stable; Instantaneous power failure non-stop function;
Hibernation wake-up delay setting function Over torque detection function;
Selection of multiple upper limit frequency setting sources;
Speed tracking restart function: realizing the smooth start without impact of the rotating motor;
Forward and reverse rotation inching function: Users can freely define the multi-function shortcut key. The modified function code which is different from the factory default can be quickly browsed by setting the parameter;
Automatic voltage adjustment function: When the grid voltage changes, the constant output voltage is automatically kept; The oscillation suppression function effectively solves the problem of low-frequency oscillation of high-power motor;
Multiple fault protection functions: overcurrent, overvoltage, undervoltage, over-temperature, phase loss, overload and other protection functions.
