4.13.2 Square Reduction V/FPattern Operation
Square reduction V/F pattern is ideal for loads such as fans and pumps. It provides non-
linear acceleration and deceleration patterns to sustain torque throughout the whole
frequency range.

BAS-07 V/F
Pattern
Sets the parameter value to ‗1 (Square)‘ or ‗2 (Square2)‘ according to the
load‘s start characteristics.
Setting
Function
1
Square
The inverter produces output voltage proportional to 1.5
square of the operation frequency.
3
Square2
The inverter produces output voltage proportional to 2
square of the operation frequency. This setup is ideal for
variable torque loads such as fans or pumps.
