3.14.10 14-9* Fault Settings

14-90 Fault Level
This is an array parameter with 26 elements. Each of the bits can
be configured to any of the following options. Use this
parameter to customize fault levels.
Option:
[0] Off
[1] Warning
[2] Trip
[3] Trip Lock
[4] Trip w. delayed
reset
Function:
isolated from the frequency converter when operated
from an external supply.
Function:
options over a power cycle.
Function:
Freezes the current settings and
prevents unwanted changes when
missing or defective options are
detected.
Changes frequency converter settings
and is used when modifying the
system configuration. This parameter
setting returns to [0] Protect Option
Config. after an option change.
Function:
Use [0] Off with caution as it ignores all
warnings and alarms for the selected
source.
Changing a fault level from default option
[3] Trip Lock to [2] Trip leads to the
automatic reset of the alarm. For alarms
involving overcurrent, the frequency
converter has a hardware protection that
issues a 3-minute recovery after 2
consecutive overcurrent incidents. This
hardware protection cannot be overruled.
This option adds a delay between
automatic resets, otherwise it is the same
as option [2] Trip. The delay prevents a
situation where reset is attempted
repeatedly for an overcurrent situation.
Hardware protection of the frequency
converter forces the 3-minute recovery time
after 2 consecutive overcurrents (within a
short time window).
