Note:
• When you use A1-04 and A1-05 [Password Setting] to set a password, you cannot change the values set in A1-01 to A1-03, A1-07,or
A2-01 to A2-32.
• When H1-xx = 7C [MFDI Function Select = Prg Lock], you must activate the terminal to change parameter settings.
• When you use Modbus communications, you must send the Enter command from the controller to the drive and complete the serial
communication write process before you can use the keypad to change parameter settings.

Note:
When you change the A1-02 setting, the parameter values specified by A1-02 are changed to their default values.
Sets the control method for the drive application and the motor.
0 : V/f Control
Use this control method in these applications and conditions:
• For general variable-speed control applications in which a high level of responsiveness or high-precision speed
control is not necessary.
• To connect more than one motor to one drive
• When there is not sufficient data to set the motor parameters
• When it is not possible to do Auto-Tuning. The speed control range is 1:40.
2 : OLVector
Use this control method for general variable-speed control applications in which high-precision speed control is
necessary. In this control method, a feedback signal from the motor is not necessary to have high torque response
and high torque when operating at low speeds. The speed control range is 1:120.
5 : PM OLVector
The drive controls an IPM motor or SPM motor in this control method. Use this control method for general
variable-speed control applications in which a high level of responsiveness or high-precision speed control are not
necessary. The speed control range is 1:20.
6 : PM AOLVector
The drive can control an IPM motor in this control method. Use this control method for general variable-speed
control applications in which high-precision speed control and torque limit are necessary. The speed control range
is 1:20. The speed control range is 1:100 when n8-57 = 1 [High-Freq Injection = Enabled].
8 : EZ Vector
The drive controls induction motors and PM motors in this control method. This control method uses an easier
procedure to operate motors with more efficiency. Use this control method for derating torque applications. For
example, fans and pumps.
