5.3.3.2 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 the base frequency. The inverter provides a non-
linear V/F acceleration and deceleration pattern to sustain enough torque throughout the speed
range.
Square Reduction V/F pattern Operation - Setting Details
Sets the parameter value to ‘1 (Square)’ or ‘2 (Square2)’ according to the
load’s start characteristics.
The inverter produces output voltage proportional to 1.5
square of the operating frequency.
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.
