·
Set the rated motor frequency as the maximum voltage frequency, and set the rated
motor voltage as the maximum voltage.
·
The vertical-axis load or the load with high viscous friction may require high torque at
low speed. If the torque is insufficient at low speed, increase the voltage in the low-
speed range by 1 V, provided that no overload (OL1 or OL2) is detected. If an overload
is detected, decrease the set values or consider the use of an Inverter model with a
higher capacity.
·
The required torque of fan or pump control increases in proportion to the square of the
speed. By setting a quadratic V/f pattern to increase the voltage in the low-speed
range, the power consumption of the system will increase.
