The max output frequency is the highest permissible frequency of the inverter, as shown in Fig.4-2 .
Basic running frequency is the lowest frequency when the inverter output the highest voltage and it is usually rated
frequency of the motor, as shown in Fig4-2 as
FB
.
The ma x output voltage is the relevant output voltage w hen the inverter output basic running frequency and it is usually
rated voltage of the motor
,
as shown in Fig.4-2 as Vmax.

In order to compensate the torque drop at low frequency
,
the inverter can be boost the output voltage so as to boost the
torque, the torque boost of constant torque c urve and square torque curve are shown in Fig. 4-3 as
