Initialize Parameters

Sets parameters to default values.

0

(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. Set A1-03 = 1110 to reset to the saved parameter settings.

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

  1. Set parameters correctly for the application.

  2. 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.

  3. 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.
