When the torque boost is set to 0.0%,the inverter is in the automatic torque boost state.
Cut-off point of torque boost:The torque boost is valid under this point,and the torque
boost is invalid when exceeding this set frequency.

When motor In no load or light load run at constant speed,it will adjust the inverter
output voltage and save energy through detecting the load current.
Note:This function is especially effective for fan and pump load

When V/F is running and the motor light load and low frequency (average 5.00 Hz ~
20.00 Hz),it may appear Mechanical and electrical parameters of resonance.At the
moment,Motor speed fluctuate, the inverter output current, bus voltage fluctuate.Serious
when may damage the load equipment downtime or frequency inverter.At the moment,it
