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 = 1B [MFDI Function Select = Program Lockout], you must activate the terminal to change parameter settings.
• When you use MEMOBUS/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 Selection
No.
(Hex.)
Name Description
Default
(Range)
A1-02
(0102)
Control Method Selection
Sets the control method for the drive application and the motor.
0
(0, 2)
Note:
When you change the control methods, 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.
• Applications in which more than one motor are connected 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 : Open Loop Vector
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.
■ A1-03: Initialize Parameters
No.
(Hex.)
Name Description
Default
(Range)
A1-03
(0103)
Initialize Parameters
Sets parameters to default values.
0
(0 - 2220)
Note:
• After you initialize the drive, the drive automatically sets A1-03 = 0.
• User Parameters can save the parameter values for your application and use these values as default values for drive initialization.
0 : No Initialization
1110 : User Initialization
Sets parameters to the values set by the user as user settings. Set o2-03 = 1 [User Parameter Default Value = Set
defaults] to save the user settings.
You can save the parameter settings that were adjusted for the test run as user-set default values to the drive.
When you make changes to the parameter values after you save the settings as User Parameter Settings, the drive
will set the parameters to the User Parameter Setting value when you initialize with A1-03 = 1110.
