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.

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 102
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
Refer to Setting 0: 3-Wire Sequence on page 96
for more information on digital input functions.
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.
Notes on Parameter Initialization
will not be reset when the drive is initialized by setting A1-03 = 2220 or 3330. Although
the control mode in A1-02 is not reset when A1-03 is set to 2220 or 3330, it may change when an application preset is selected.
