Stall control
mode
If the utility supply voltage declines, the output frequency will decrease to
maintain a constant motor V/f relation. In some applications the motor is
required to operate at the desired set speed, regardless of supply line
voltage variations. In this situation, the under voltage control is disable,
the frequency will not decrease as the utility supply voltage decreases.
This could lead to under exciting the motor, resulting in a large increase in
motor current during under voltage conditions.

V/f curve
selection
Voltage / frequency curve selection.
0: linear
The voltage of the motor changes linearly with the frequency in the
constant flux area from 0 Hz to the motor rated frequency where the
rated voltage is supplied to the motor. Linear V/f curve should be used in
constant torque applications.
1: multi-point V/f
User can program multi-point V/f based on the needs of application. See
Fig.6-D2
2: 1.2-power V/F
3: 1.4-power V/F
4: 1.6-power V/F
5: 1.8-power V/F
6: squared V/f
Squared V/f curve can be used in applications where torque demand of
the load is proportional to the square of the speed, e.g in centrifugal fans
and pumps.
