H2-03: A6 (BP BAS Interlock)
o1-16: 2 (Drive/Bypass)
Note:
After performing an OEM Bypass Initialization, H1-03 to H1-05, H2-01 to H2-03, and o1-16 will be displayed in the Modified Parameters
list.
Notes on Parameter Initialization
The parameters shown in
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.
