Using V/f Control Mode
V/f control mode is preset at the factory.
Control Mode Selection (n002) = 0: V/f control mode (factory setting)
1: Vector control mode
Adjusting Torque According to Application
Adjust motor torque by using the V/f pattern and full-range automatic
torque boost settings.
V/f Pattern Setting
Set the V/f pattern in n011 to n017 as described below. Set each pattern
when using a special motor (e.g., high-speed motor) or when requiring
special torque adjustment of the machine.
Note: The values in the parentheses are for the 400 V Class of Inverters.
