Setting 2: Open Loop Vector
• For general, variable-speed applications.
• For applications requiring precise speed control, quick response, and higher torque at low
speeds.
Setting 5: PM Open Loop Vector
For operating SPM, IPM, and various permanent magnet motors. Takes advantage of Energy
Saving features when operating with derated torque.

A1-03: Initialization
Resets parameter settings back to their original default values. After the initialization the
parameter automatically returns to 0.
Setting 1110: User Initialize
The modified drive parameters are returned to the values selected as user settings. User
settings are stored when parameter o2-03 = “1: Set Defaults”.
Note: A “user-initialization” resets all parameters to a user-defined set of default values that were
previously saved to the drive. To clear the user-defined default values, set parameter o2-03 to
“2”.
Setting 2220: 2-Wire Initialization
Resets all parameters back to their original default settings with digital inputs S1 and S2
configured as forward run and reverse run, respectively.
Setting 3330: 3-Wire Initialization
The drive parameters are returned to factory default values with digital inputs S1, S2, and S5
configured as run, stop, and forward/reverse respectively.
Setting 5550: oPE04 Reset
If parameters on a certain drive have been edited and then a different terminal block is
installed with different settings saved in its built-in memory, an oPE04 error will appear on
the display. To use the parameter settings saved to the terminal block memory, set A1-02 to
“5550”.
Notes on Parameter Initialization
The parameters shown in Table 1.1 will not be reset when the drive is initialized by setting
A1-03 = 2220 or 3330. Although the control mode in A1-02 is not reset when A1-03 is set to
2220 or 3330, it may change when an application preset is selected.
