Section V Parameter Function Table
parameters which affect automatic torque enhance :
Actual value torque component S15
b06/b19 stator resistance
F07 torque enhance value
Automatic torque enhance value = actual value of torque component * stator resistance
*torque enhance value.
100 bit: VF mode 0 speed maintain function
0 VF mode 0 Speed No Output: Output frequency is less than 0.5Hz, stop PWM output to
reduce the switching loss.
1 VF mode keep 0 speed: the output frequency is 0Hz, in accordance with the DC braking
current of starting F26, keep 0 speed.

down the torque curve torque boost
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.
