Z1-12
(85D1) Run Delay Time
Run Delay Time
Delays the drive or bypass Run from when commanded (after
RUN, RUN ENABLE, and RUN INTERLOCK are all asserted).
Default: 0.0 s
Min.: 0.0
Max.: 300.0
Z1-13
(85D2) Pre-Interlock Run
Select
Pre Int Run Sel
0: Disable
1: Enable
Allows running at a preset speed starting immediately upon a Run
command, ignoring the BAS Interlock Input. The drive frequency
reference stays at this preset speed until the Run Delay time
(Z1-12) times out.
0: Disabled
1: Enable delay time only
Default: 0
Range: 0, 1
Z1-14
(85D3) Run Delay Frequency
Reference
Run Delay Fref
Frequency used while delaying the Run command.
Default: 60.0
Hz
<1>
Min.: 0.0
Max.: 60.0
Z1-15
(85D4) Interlock Wait Time
Interlck Wait
Upon entering a Run command, the damper actuator output will
be asserted. When an input is programmed for Interlock and the
time set to this parameter is reached before the Interlock input
goes active, a fault will be declared.
A setting of 0.0 will never time out.
Default: 0.0 s
Min.: 0.0
Max.: 300.0
Z1-24
(85DD) Contactor Open Delay
Time
Kx Open Delay
Sets the time to delay after commanding the drive output
contactor K2 or bypass contactor K3 or 2-Motor OR/AND
contactors K4 and K5 to open to allow the contacts to open.
Default: 0.2 s
Min.: 0.0
Max.: 5.0
Z1-25
(85DE) Contactor Close Delay
Time
Kx Close Delay
Sets the time to delay after commanding the drive output
contactor K2 or bypass contactor K3 or 2-Motor OR/AND
contactors K4 and K5 to close to allow the contacts to close.
Default: 0.2 s
Min.: 0.0
Max.: 5.0
Z1-27
(08E0) Phase Loss Brownout
Voltage Level
PL Brownout V
Sets the voltage level below which is considered a brownout
condition.
Default: 98 V
Min.: 0
Max.: 150
Z1-28
(85E1)
Phase Loss Brownout
Detection Time
PL Brownout T
PL Brownout T
Sets the time that the input voltage is continuously measured to
be below the Brownout Voltage level before declaring a
Brownout fault.
Default: 3.0 s
Min.: 0.0
Max.: 300.0
Z1-29
(85E2) Phase Loss Blackout
Voltage Level
PL Blackout V
Sets the voltage level below which is considered a blackout
condition. When the input voltage is measured below this level,
a Blackout fault will be declared.
Default: 0 V
Min.: 0
Max.: 150
Z1-30
(85E3) EF0 Fault Delay Time EF0 Flt Delay T
Sets the time between declaring a drive fault and opening the
drive and bypass contactors.
Default: 1.0 s
Min.: 0.0
Max.: 300.0
Z1-31
(85E4) Loss of Load Detection
Enable
Loss of Load En
0: Disable
1: Enable Fault
2: Enable Alarm
0: Disable
1: Enable and declare fault.
2: Enable and alarm only
Default: 0
Range: 0 to 2
Z1-32
(85E5) Loss of Load Drive
Frequency
Load Drive Freq
Sets the value to which the drive output frequency must be equal
to or greater than for the drive to detect a loss of load.
Default: 60.0
Hz
<1>
Min.: 0.0
Max.: 60.0
