5-1-2 Setting the Control Mode (n002)
•
The 3G3MV Inverter operates in vector or V/f control mode to be selected according to the application.
•
These two modes have the following characteristics.
Vector Control Mode
The Inverter in vector control mode calculates the vector of the operating condition of the motor. Then
the 150% rated output torque of the motor is provided at an output frequency of 1 Hz. Vector control
provides more powerful motor control than V/f control and makes it possible to suppress speed fluctua-
tion regardless of changes in loads. Normally set the Inverter to this mode.
V/f Control Mode
This mode, which is used by conventional general-purpose inverters, is convenient when replacing a
conventional model with the 3G3MV Inverter because the Inverter in this mode can be operated without
considering the constants of the motor. Furthermore, set the Inverter to this mode if the Inverter is con-
nected to more than one motor or special motors such as high-speed motors.

Note 1.
This parameter is not initialized by setting n001 (parameter write-prohibit selection/parameter
initialization) to 8, 9, 10, or 11 for parameter initialization. Be sure to change the parameter
n002 before changing the control mode.
Note 2.
Each of the following parameters is initialized according to the control mode set in this param-
eter. The default value varies with the control mode. Therefore, be sure to set the following
parameters after setting the control mode in n002.
