• 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.
2
(0 - 4)
Note:
Parameters that are determined by A1-02 are changed back to their default settings whenever the control method is changed.
Sets the control method for the drive application and the motor.
0 : V/f Control
Use this control method for general variable speed control applications that do not require a high level of
responsiveness and high-precision speed control and connect multiple motors to a single drive. Also use this
control method when there is not enough data to set the motor parameters or when it is not possible to perform
Auto-Tuning. The speed control range is 1:40.
1 : V/f Control w/ PG
Use this control method for general applications that do not require a high level of responsiveness but require
high-precision speed control. Also use this control method when it is not possible to perform Auto-Tuning
because there is not enough data to set the motor parameters. The speed control range is 1:40.
2 : Open Loop Vector Control
Use this control method for general variable speed control applications that require high-precision speed control.
This control method achieves high torque response as well as high torque even when operating at low speeds,
even without a feedback signal from the motor. The speed control range is 1:120.
3 : Closed Loop Vector
Use this control method for general variable speed control applications that require high torque response, high-
precision speed control up to zero speed, and high-precision torque control. This method requires a speed
feedback signal from the motor. The speed control range is 1:1500.
4 : Advanced Open Loop Vector
This is a control method for induction motors. Use this control method for applications that require high-precision
speed control.
This control method achieves high speed and torque response as well as high torque even when operating at low
speeds. The speed control range is 1:200.

A1-03: Initialize Parameters
No.
(Hex.)
Name Description
Default
(Range)
A1-03
(0103)
Initialize Parameters
Sets parameters to default values.
0
(0 - 2220)
Note:
• A1-03 = 0 is automatically set after initializing the drive.
• User Parameter Settings let the user save parameter values needed for the application, and have the drive use those parameter settings
as the default value when initializing the drive.
• When using the 2 motor switchover function, turn off the terminal to which
H1-xx = 16 [Terminal Sx Function Selection = Motor 2
Selection] has been assigned, and then change the A1-03 setting. An incorrect procedure will trigger oPE08 [Parameter Selection
Error] .
0 : No Initialization
1110 : User Initialization
Resets parameters to the values selected by the user as User Settings. Set o2-03 = 1 [User Parameter Default
Value = Set defaults]
to save the user settings.
Users can save the parameter settings adjusted for the test run as user-set default values to the drive. Set A1-03 =
1110 to reset to the saved parameter settings.
Follow the following steps to save User Parameter setting values, and to perform a User Initialization.
1. Set parameters appropriately for the application.
