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 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.
