4.4 Basic Parameter Adjustments
4.4 Basic Parameter 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 331 as required for a complete listing of drive parameters.
◆ Control Mode Selection
■ 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: Be sure to save all changed parameter settings by setting o2-03=”1” before
initializing the drive. Your settings will be lost if a 2-wire or 3-wire initialization
using 2220, or 3330 if performed without first saving user parameters. Refer to
Back-up of Parameter Values: o2-03 on page 173.
