voltage

Torque boost is used to increase the output voltage during low-frequency operation and
improve the low-frequency torque characteristics of V/F control.

The setting range of the torque boost voltage is 0~300‰. When the set value is 0, there
is no increase, but when the set value is 300‰, the increase range is maximum.

voltage

AVR function refers to the automatic adjusting function of the output voltage: when the
AVR function is disabled, the output voltage will change with the change of the input
voltage (or the DC bus voltage); when the AVR function is enabled, the output voltage
will not change with the change of the input voltage (or the DC bus voltage), and the
output voltage will basically keep constant within the normal input voltage variation
range.
