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 connected to more than one motor or spe-
cial motors such as high-speed motors.

Value Description
0 V/f control mode
1 Vector control mode (open loop)
Note 1. This parameter is not initialized by setting n001 (parameter write-prohibit selec-
tion/parameter initialization) to 8 or 9 for parameter initialization.
Note 2. Each of the following parameters is initialized according to the control mode set
in this parameter. The default value varies with the control mode. Therefore, be
sure to set the following parameters after setting the control mode in n002.
