V/F Curve
(Voltage-Frequency character) Base frequency can be set from 5~500Hz arbitrarily, and there are three kinds of curve: constant torque ,Dec torque 1 and Dec torque 2.
Torque Boost Manual Setting: 0~20% of rated output, Auto-boost: Automatically boost torque according to output current.
Auto Energy-saving running Adjust output voltage and slip compensation properly according to output current, which will make the motor working in highest efficiency.
