Rely on power supply voltage compensate function, while motor rated
Rated output voltage voltage is 100%, set it at the range of 50-100%(output can not over input
voltage).
Voltage While power supply voltage fluctuates, it can auto-keep constant output
auto-adjustment voltage.
Auto energy-saving While under V/F control mode, according to load situation, auto-optimize
running output voltage to save energy.
Basic
Auto-limit current Auto-limit the current while running to prevent over current break trouble.
