4.6 Basic Drive Setup Adjustments
This section explains the basic settings required for initial drive operation. Checking these basic parameter settings will help
to ensure a successful drive start-up. Refer to
Parameter List on page 249 for a complete listing of drive parameters if more
information is required for parameters not listed in this section.
n
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.
Note: When changing control modes, all parameter settings depending upon the setting of A1-02 will be reset to the default.
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 1:200 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. In this case, perform High Frequency Injection
Parameter Tuning after setting the motor parameters. High Frequency Injection cannot be used with an SPM motor.
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 0: No Initialize
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.
