Learning Basic Features
Square Reduction V/F Pattern Operation
Square reduction V/F pattern is ideal for variable torque loads such as fans and pumps that do not
require high torque at frequencies lower than base frequency. The inverter provides a non-linear
V/F acceleration and deceleration pattern to sustain enough torque throughout the speed range.

V/F Pattern
Sets the parameter value to 1 (Square) or 2 (Square2) according to the
load’s start characteristics.
Configuration
Function
1
Square
The inverter produces output voltage
proportional to 1.5 square of the operating
frequency.
3
Square2
The inverter produces output voltage
proportional to 2 square of the operating
frequency. This setup is ideal for variable torque
loads such as fans or pumps.
