A1-02: Control Method Selection
Selects the Control Method (also referred to as the control mode) that 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.
No. Parameter Name Setting Range Default
A1-02 Control Method Selection 0, 1, 2, 3, 5, 6, 7 2
Control Modes for Induction Motors (IM)
Setting 0: V/f Control for Induction Motors
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. The
speed control range is 1:40.
Setting 1: V/f Control with PG Speed Feedback
Use this mode for general-purpose applications that require high speed accuracy but do not require high dynamic response.
This control mode is also used when the motor parameters are unknown and Auto-Tuning cannot be performed. The speed
control range is 1:40.
Setting 2: Open Loop Vector Control
Use this mode for general, variable-speed applications with a speed control range of 1:120 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.
Control Modes for Permanent Magnet Motors (SPM or IPM)
Note:
PM motor control modes are not available on 600 V class drives, CIMR-Ao5oooooooo.
Setting 5: Open Loop Vector Control for PM
Use this mode when running a PM motor in variable torque applications that benefit from energy efficiency. The drive can
control an SPM or IPM motor with a speed range of 1:20 in this control mode.
Setting 6: Advanced Open Loop Vector Control for PM
Use this mode to operate an IPM motor for constant torque applications. Using High Frequency Injection, a speed control
range as high as 1:100 is possible. Refer to Control Mode Selection on page 30 for details.
Setting 7: Closed Loop Vector Control for PM
Use this mode for high-precision control of a PM motor in constant torque or variable torque applications. The speed control
range reaches 1:1500. A speed feedback signal is required.

A1-03: Initialize Parameters
Resets parameters to default values. After initialization, the setting for A1-03 automatically returns to 0.
No. Parameter Name Setting Range Default
A1-03 Initialize Parameters 0, 1110, 2220, 3330, 5550 0
Setting 1110: User Initialize
Resets parameters to the 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 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.
Refer to Setting 40, 41: Forward Run, Reverse Run Command for 2-Wire Sequence on page 214 for more information on
digital input functions.
Setting 3330: 3-Wire Initialization
Resets parameters to default settings with digital inputs S1, S2, and S5 configured as Run, Stop, and Forward/Reverse
respectively. Refer to Setting 0: 3-Wire Sequence on page 208 for more information on digital input functions.
