Z1-12: Run Delay Time
No.
(Hex.)
Name Description
Default
(Range)
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)
■

No.
(Hex.)
Name Description
Default
(Range)
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, 1)
0 : Disabled
1 : Enable time delay only
■
Z1-14: Run Delay Frequency Reference
No.
(Hex.)
Name Description
Default
(Range)
Z1-14
(85D3)
Run Delay Frequency
Reference Sets the frequency that the bypass uses when it delays the Run command. 60.00 Hz
(0.00 - Max. Freq.)
Note:
Actual values depend on unit settings of drive parameters o1-03, o1-09, o1-10, and o1-11 .
