Z3-13: BACNet Command Register Retention
WARNING! Sudden Movement Hazard. Setting this parameter to 2 or 3 will allow the bypass unit to start before receiving a valid network
message. Clear all personnel from the drive, motor, and machine area before reapplying power. Failure to comply could result in injury to
personnel.
Determines whether to restore the frequency reference, bypass command, or both upon the reapplication of power after losing
power. 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 Default
Z3-13 BACNet Command Register Retention 0 to 3 0
Setting 0: Disabled
Reapplying power will not restore any BACNet objects.
Setting 1: Reference Only
Reapplying power restores the frequency reference object (AV2).
Setting 2: Run/Stop Only
Reapplying power restores various command objects including the Run commands. Refer to BACNet Values Restored When
Z3-13 = 2 or 3 on page 217 for a list of command objects.
Setting 3: Ref & Run/Stop
Reapplying power restores the frequency reference object (AV2) and various command objects. Refer to BACNet Values
Restored When Z3-13 = 2 or 3 on page 217 for a list of command objects.
