Z1-12
(85D1)
Run Delay Time Delays the drive or bypass Run from when commanded (after RUN, RUN ENABLE, and
RUN INTERLOCK are all asserted).
0.0 s
(0.0 to 300.0 s)

Z1-13
(85D2)
Pre Interlock Run Select Lets the bypass run at a preset speed starting when it receives a Run command, and it
ignores the BAS Interlock Input. The drive frequency reference stays at this preset speed
until Z1-12 [Run Delay Time] is expired.
0 : Disabled
1 : Enable time delay only

Run Delay Frequency
Reference
Sets the frequency that the bypass uses when it delays the Run command. 60.00 Hz
(0.00 - Max. Freq.)
431
Z1-15
(85D4)
Interlock Wait Time When you enter a Run command, it asserts the damper actuator output. When you program
an input for Interlock and the time set to this parameter expires before the Interlock input
activates, it will trigger a fault.
Note:
Set this parameter to 0.0 s to disable this function.
0.0 s
(0.0 - 300.0 s)
431
Z1-16
(85D5)
Energy Savings Mode When you enter a Run command, it asserts the damper actuator output. When you program
an input for Interlock and the time set to this parameter expires before the Interlock input
activates, it will trigger a fault.
0 : Disabled
1 : Frequency
2 : Frequency + Current
Note:
If the motor is running in reverse, Energy Savings will not function.

Energy Savings
Frequency Ref
Sets the value of the drive frequency reference for use in comparison to enter or exit
Energy Savings Mode.
60.00 Hz
(0.00 - Max. Freq.)

Z1-18
(85D7)
Energy Savings Output
Cur Level
Lets the system switch when the output current is more than this level of motor rated
current for the time set in Z1-22, Energy Time.
0.0%
(0.0 - 100.0%)

Z1-19
(85D8)
Energy Savings Fref
Deadband
Sets the tolerance around the drive frequency reference value during comparisons to enter
or exit Energy Savings Mode.
Note:
Units, default, and range are different for different o1-03 [Frequency Display Unit
Selection] values.
0.50 Hz
(0.00 - 5.00 Hz)
