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:
Function:
[2]
Trip
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.

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:
Function:
[4]
Trip w.
delayed reset
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).
