A1-02: Control Method Selection
■
Selects the Control Method (also referred to as the "control mode") the drive uses to operate the motor. If the drive is set
up to run two motors, then A1-02 determines the control mode for motor 1.
Note: When changing control modes, all parameter settings depending upon the setting of A1-02 will be reset to the default.
No.
A1-02
Control Modes for Induction Motors (IM)
Setting 0: V/f Control
V/f Control is for simple speed control and multiple motor applications with low demands to dynamic response or speed
accuracy. This control mode should be used when the motor parameters are unknown and Auto-Tuning cannot be
performed.
Setting 2: Open Loop Vector Control
For general, variable-speed applications 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
For general, variable-speed applications that requiring precise speed control down to zero speed, fast torque response, or
precise torque control. A speed feedback signal from the motor is required.
A1-03: Initialize Parameters
■
Resets parameters back to the original default values. After initialization, the setting for A1-03 automatically returns to 0.
No.
A1-03
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: A "user-initialization" resets all parameters to a user-defined set of default values that were previously saved to the drive. To
clear the user-defined default values, set parameter o2-03 to 2.
Setting 2220: 2-Wire Initialization
Resets all parameters back to their original default settings with contact inputs S1 and S2 configured as Forward run and
Reverse run, respectively.
