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,
List on page 167 as required for a complete listing of drive parameters.

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.

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.
n 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. .
