n A1-02: Control Method Selection
Selects the Control Method (also referred to as the control mode) the drive uses to operate the motor. Parameter A1-02
determines the control mode for motor 1 when the drive is set up to run two motors.
Note: When changing control modes, all parameter settings depending upon the setting of A1-02 will be reset to the default.
Control Modes for Induction Motors (IM)
Setting 0: V/f Control
Use this mode for simple speed control and for multiple motor applications with low demands to dynamic response or
speed accuracy. This control mode is also used when the motor parameters are unknown and Auto-Tuning cannot be
performed.
Setting 2: Open Loop Vector Control
Use this mode for general, variable-speed applications with a speed control range of 1:200 that require precise speed
control, quick torque response, and high torque at low speed without using a speed feedback signal from the motor.
Setting 3: Closed Loop Vector Control
Use this mode for general, variable-speed applications that require precise speed control down to zero speed, quick
torque response or precise torque control, and a speed feedback signal from the motor. The speed control range is up to
1:1500.

A1-03: Initialize Parameters
Resets parameters to default values. After initialization, the setting for A1-03 automatically returns to 0.
Setting 1110: User Initialize
Drive parameters are reset to values selected by the user as User Settings. User Settings are stored when parameter o2-03
is set to “1: Set defaults”.
Note: User-initialization resets all parameters to a user-defined set of default values that were previously saved to the drive. Set
parameter o2-03 to 2 to clear the user-defined default values.
Setting 2220: 2-Wire Initialization
Resets parameters to default settings with digital inputs S1 and S2 configured as Forward run and Reverse run,
respectively.
Notes on Parameter Initialization
The parameters shown in Table 2. 1 will not be reset when the drive is initialized by setting A1-03 = 2220.
