Note 1. [ ] values indicate those for 400-V-class Inverters.
Note 2. For 5.5- and 7.5-kW Inverters, this value is set to 10.0 V for 200-V-class models and to 20.0 V
for 400-V-class models.

• 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 set-
ting a quadratic V/f pattern to increase the voltage in the low-speed range, the power consumption of
the system will increase.
