4.6 Basic Drive Setup Adjustments
This section explains the basic settings required for initial drive operation. Checking these
basic parameter settings during start-up will help to ensure a successful drive start-up.
If more information is required for parameters not listed in this section, Refer to Parameter
List on page 167 as required for a complete listing of drive parameters.
u
Control Mode Selection: A1-02
Note: 1. Be sure to perform Auto-Tuning when using one of the vector control modes.
2. Reinitializing the drive does not reset A1-02 to the factory default value.
n
Available Control Modes
Three motor control modes are available. Select the control mode that best suits the application
in which the drive will be used.
Control Mode Parameter Main Applications
V/f Control
A1-02 = 0
(default)
• General variable speed applications
• For running multiple motors from a single drive
• When replacing a drive in which parameter settings are
unknown.
Open Loop Vector Control A1-02 = 2
• General variable speed applications
• Applications requiring high precision, high speed control.
PM Open Loop Vector Control A1-02 = 5
Variable torque applications employing permanent magnet motors
and energy savings.
u
Initialize Parameter Values: A1-03
Parameter A1-03 (Initialize Parameters) resets all parameters to the original default values.
Note: 1. Save all changed parameter settings by setting o2-03 = ”1” before initializing the drive. Settings will
be lost if performing a 2-Wire or 3-Wire initialization using 2220 or 3330 if user parameters are not
saved first.
2. If using Open Loop Vector Control (A1-02 = 2), Auto-Tuning will need to be performed again after
the drive is initialized. Refer to Auto-Tuning on page 113 for details.

Different Methods of Drive initialization
1110: Resets all parameters to user-defined default values
A 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 those values.
Note: Set o2-03 to “1” to save the current parameter settings and changes for a “user-initialization.” After
saving all parameter setting changes, parameter o2-03 automatically returns to 0. .
