No. Parameter Name Setting Range Default
A1-02 Control Method Selection 0, 1, 2, 3, 5, 6, 7 0
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 1:200 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.
Control Modes for Permanent Magnet Motors (SPM or IPM)
Setting 5: Open Loop Vector Control for PM
Use this mode for general, variable-speed applications with low demands on dynamic response or speed accuracy. 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 for general, variable speed applications that require precise speed control and torque limit. Set High Frequency
Injection parameter n8-57 to 1 to achieve a speed control range as high as 1:100.
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.
n 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.
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.
Setting 5550: oPE04 Reset
An oPE04 error appears on the digital operator when a terminal block with settings saved to its built-in memory is installed
in a drive that has edited parameters. Set A1-03 to 5550 to use the parameter settings saved to the terminal block memory.
