Factory default value 50.00Hz
Setup range 0.00Hz~ maximum output frequency
To compensate the low frequency torque characteristics of V/F control, it can boost the output
voltage of the inverter at the time of low frequency.
If the torque boost is set to be too large, the motor may be over heat, and the inverter may be
over current. In general, the torque boost shall not exceed 8.0%.
Adjusting this parameter effectively can avoid over current upon startup. For the relatively large
loads, it is recommended to increase this parameter. For the small loads, this parameter value
may be reduced.
When the torque boost is set to 0.0, the inverter will adopt auto torque boost.
Cutoff frequency of torque boost: Under this frequency, the torque boost is enabled. If it
exceeds this setup frequency, the torque boost is inactive. Refer to Fig.6-3 for details.
machine.
