Torque increase is mainly used to improve the low-frequency torque characteristics under
sensorlessV / F control mode.
Torque boost is too low, weak low speed motor
Torque boost is too high, motor over-excitation operation, large inverter output current, and
low efficiency.
The setting frequency of the inverter is lower than the frequency of the torque rising,the
torque rising will be valid;over than the setting frequency the torque rising will invalid.
F09 Accelerate time: accelerate time from 0Hz to maximum frequency.
F10 Decelerate time: decelerate time from maximum frequency to 0Hz

Percentage of output
voltage
The percentage of the actual output voltage and the rated output voltage.
Used to adjust the output voltage,output voltage＝inverter rated output voltage*percentage
of output voltage.
Inverter output maximum frequency allowed is also the setting basis of acceleration /
deceleration time.
This parameter setting, you should consider characteristics of the motor speed and capacity.
Lower frequency~Upper frequency
F13 Lower frequency: the lower limit of the output frequency.
F14 Upper frequency: the uppper limit of output frequency.
When the frequency setting command is higher than the upper frequency, the operating
frequency
Will be the upper frequency;When the frequency setting command below the lower frequency ,
