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. Also refer to digital input functions, Setting 0: 3-Wire Sequence on page 236.
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 A1-03 to 5550.
Notes on Parameter Initialization
The parameters shown in Table 5.1 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.
