122 YASKAWA ELECTRIC TOEP C710606 09B YASKAWA AC Drive V1000 Installation & Start-Up Manual4.6 Basic Drive Setup Adjustments4.6 Basic Drive Setup AdjustmentsThis section explains the basic settings required for initial drive operation. Checking thesebasic 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 ParameterList on page 305 as required for a complete listing of drive parameters.◆ Control Mode Selection: A1-02■ Available Control ModesThree motor control modes are available. Select the control mode that best suits theapplication in which the drive will be used.◆ Initialize Parameter Values: A1-03Parameter A1-03 (Initialize Parameters) resets all parameters to the original default values.Note: Save all changed parameter settings by setting o2-03=”1” before initializing the drive. Yoursettings will be lost if a 2-wire or 3-wire initialization using 2220, or 3330 if performed withoutfirst saving user parameters. Refer to Backing Up Parameter Values: o2-03 on page 164.■ Different Methods of Drive initialization1110: Resets all parameters to user-defined default valuesA user-initialization resets all parameters to a user-defined set of default values previouslysaved 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. Refer toVerifying Parameter Settings and Backing Up Changes on page 163.2220: 2-Wire InitializationReturns all parameters to factory default values for 2-wire control.Control Mode Parameter Main ApplicationsV/f Control A1-02 = 0(default)• General variable speed applications, particularly useful forrunning multiple motors from a single drive• When replacing a drive in which parameter settings areunknown.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 motorsand energy savings.
