A1-03

(0103)

Initialize Parameters

Sets parameters to default values.

(0 - 3330)

Note:

After you initialize the drive, the drive automatically sets A1-03 = 0.
User Parameters can save the parameter values for your application and use these values as default values for drive initialization.
To use the 2 motor switchover function, first turn OFF the terminal to which H1-xx = 16 [MFDI Function Selection = Motor 2 Selection] is set, then change the A1-03 setting. An incorrect procedure will trigger oPE08 [Parameter Selection Error].

0

No Initialization

1110

User Initialization

Sets parameters to the values set by the user as user settings. Set o2-03 = 1 [User Parameter Default Value = Set defaults] to save the user settings.

You can save the parameter settings that were adjusted for the test run as user-set default values to the drive. When you make changes to the parameter values after you save the settings as User Parameter Settings, the drive will set the parameters to the User Parameter Setting value when you initialize with A1-03 = 1110.

Follow this procedure to save User Parameter setting values, and to do a User Initialization.

Set parameters correctly for the application.
Set o2-03 = 1 [User Parameter Default Value = Set defaults].

This saves parameter settings for a User Initialization.

The drive will then automatically set o2-03 = 0.
Set A1-03 = 1110 to reset to the saved parameter settings.

When you initialize the drive, the drive sets the parameter values to the User Parameter setting values.

2220

2-Wire Initialization

Sets MFDI terminal S1 to Forward Run and terminal S2 to Reverse Run, and resets all parameters to default settings.

3330

3-Wire Initialization

Sets MFDI terminal S1 to Run, terminal S2 to Stop, and terminal S5 to FWD/REV, and resets all parameters to default settings.

The drive will not initialize the parameters in Table 1 when A1-03 = 2220, 3330.

Note:

Set A1-06 [Application Preset] to let the drive automatically set the best parameter settings for the selected application. The drive does not initialize A1-02 when A1-03 = 2220, 3330.
When A1-03 = 2220, 3330, the drive automatically set A1-05 [Password Setting] = 0000. Make sure that you set the password again for applications where a password is necessary.

When you use A1-03 [Initialize Parameters] to initialize drives with software versions PRG:01013 and later, the drive will not reset A1-12. The “PRG” column on the nameplate on the right side of the drive identifies the software version. You can also use U1-25 [SoftwareNumber Flashr] to identify the software version.
