5.0 to 120.0 secs
The drive should first be set up and operating
correctly with the E-Clipse Bypass.
Comments
Verify that the Drive is set up for E-Clipse
bypass. Word value for 95.21 = [1] E-Clipse
bypass is = 0010 0000.
Default is [0] Off
• Off: Override is not being used,
• On: Uses programmed number of fault
resets,
• On, Critical: infinite number of fault
resets.
Contacts closing against the drive's DI5 will
activate Override Mode in the ACH580 VFD.
Defaults to [3] Override speed/freq
The drive will use the Hz value programmed
in 70.06
Note that [0] Constant speed/freq is similar
Defaults to [0] Forward
Defaults to 0.0 Hz. Set the value the drive
will control to in Override when 70.04 is [3].
Defaults to [1] Fault on high priority.
Defaults to 5 times.
Defaults to 5.0 seconds.
