Parameter Descriptions
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: Function:
[0] Off Use [0] Off with caution as it
ignores all warnings and alarms for
the selected source.
[1] Warning
[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

about specific fault levels.
D stands for the default setting.
X stands for a possible option.
1) Only high-power frequency converters.
2) In small and medium power frequency converters, alarm 69, Power card temperature is only a warning.
3) Warning 59 is configured in 1490.19. The current limit warning can be disabled by choice. The alarm cannot be configured.

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:
overcurrent incidents. This hardware
protection cannot be overruled.
[3] Trip Lock
[4] Trip w. This option adds a delay between
delayed reset 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).
