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.

Control Mode Selection: A1-02

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: 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.

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.

Refer to Verifying Parameter Settings and Backing Up Changes on page

2220: 2-Wire Initialization

Returns all parameters to factory default values for 2-wire control.

3330: 3-Wire Initialization

Returns all parameters to factory default values for 3-wire control.

5550: Uploads Parameter Data from the Removable Control Circuit Terminal Board

Replacing either the removable control circuit terminal board or the drive and applying main power may result in an oPE04 fault. If parameter setting

data in the removable control circuit terminal board is correct, set A1-03 to "5550" to upload the data to the drive.

Note:

Refer to Run Command Input Selection: b1-02 on page 77

Note: Initializing the drive for 2-wire sequence (A1-03 = 2220) returns all drive parameters to factory settings. Back up all parameters in the event of accidental initialization. the

data with 2-wire sequence returns all the set parameters to the factory settings.

Application Presets: A1-06

The drive features application presets to facilitate the set up of commonly used applications such as a water supply pump, conveyor, exhaust fan, HVAC

fan, compressor, hoist, and crane. Selecting one of these presets automatically sets the required parameters to the optimum values and changes the

appropriate I/O terminal settings for that specific application.

Verify all I/O signals and external sequences before operating the motor.

Users are able to make further adjustments to these settings using the Setup Mode.

<1> All general-purpose parameters are accessible when A1-06 = 0.

DWEZ Function Selection: A1-07

DriveWorksEZ is an independent software package that can be used to operate and monitor the drive with a 2 ms scan. It is fully compatible with all types

of serial communication software available on the market.
