Physical digital inputs S1 to S8 are logically ORed with the serial communications digital inputs.
Drive digital are also logically ORed with register 0001H.
WARNING!
Sudden Movement Hazard. Clear all personnel from the drive, motor, and machine area before you reapply power. Set
this parameter to 0 to prevent serial communications from triggering undesired and unexpected system operation. If you set this
parameter to 1, the system can run unexpectedly or not stop when required, even when you de-energize the physical digital input.
Failure to obey can cause injury to personnel.

Set
Z1-06 ≠ 0
to allow the bypass to start running upon application of power.
Note: 1.
Parameter is effective only when
H5-08 = 3 [Serial Communications Protocol Select = BACnet], b1-01 = 2
[Speed Reference Select = Bypass Serial], and/or b1-02 =2 [Run Command Select = Bypass Serial]
.
0 : Disabled
When you reapply power, it will not restore BACNet objects.
1 : Restore Frequency Reference Only
When you reapply power, it will restore the frequency reference object (AV2).
2 : Restore Commands Only
When you reapply power, it will restore various command objects, including the Run commands.
This setting will save BACNet objects:
BV58, BV59, BV60, BV61, BV62, BV63, BV64, BV65, BV69.
3 : Restore Commands and Freq Ref
When you reapply power, it will restore the frequency reference object (AV2) and various command objects.
