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: MFDI Function Select = 7C [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.

A1-02 Control Method
(0102)
Note:
• When you change the A1-02 setting, the parameter values specified by A1-02 are changed to their default values.
• To use the 2 motor switchover function, first turn OFF the terminal to which H1-xx: MFDI Function Select = 61 [Motor 2 Select] is
set, then change the A1-02 setting. An incorrect procedure will trigger oPE08 [Parameter Selection Error].
Selects 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.
1 : PG V/f Control
Use this control method in these applications and conditions:
• For general applications in which a high level of responsiveness is not necessary, but high-precision speed
control is necessary.
• 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.
3 : CLVector
Use this control method for general variable-speed control applications in which these qualities are necessary:
• A high level of responsiveness
• High-precision speed control up to zero speed
• High-precision torque control. A speed feedback signal from the motor is necessary for this control method. The
speed control range is 1:1500.
