n Z3-13: BACNet Command Register RetentionWARNING! Sudden Movement Hazard. Setting this parameter to 2 or 3 will allow the bypass unit to start before receiving a valid networkmessage. Clear all personnel from the drive, motor, and machine area before reapplying power. Failure to comply could result in injury topersonnel.Determines whether to restore the frequency reference, bypass command, or both upon the reapplication of power after losingpower. The feature restores all bypass command register values except the fault reset bit.Set Z1-06 ≠ 0 or Z1-38 = 2 to allow the bypass to start running upon application of power.Note: 1. Parameter is effective only when Z3-01 = 3 (Serial Communications Protocol Select = BACnet), Z1-07 = 2 (Speed Reference Select =Bypass Serial), and/or Z1-08 =2 (Run Command Select = Bypass Serial).2. Parameter is available in bypass controller software versions VST800400 and later.No. Name Setting Range DefaultZ3-13 BACNet Command Register Retention 0 to 3 0Setting 0: DisabledReapplying power will not restore any BACNet objects.Setting 1: Reference OnlyReapplying power restores the frequency reference object (AV2).Setting 2: Run/Stop OnlyReapplying power restores various command objects including the Run commands.
