14-61 Function at Inverter Overload
Option: Function:
Is used in case of steady overload
beyond the thermal limits (110% for
60 s).
[0] * Trip Select [0] Trip to make the
frequency converter trip and issue
an alarm.
[1] Derate Reduces pump speed to decrease
the load on the power section and
allowing this to cool down.
14-62 Inv. Overload Derate Current
Range: Function:
95 %* [50 - 100 %] Enter the current level (in % of
rated output current for the
frequency converter) when running
with reduced pump speed after
load on the frequency converter
has exceeded the allowable limit
(110% for 60 s).
14-90 Fault Level
Array [21]. Use this parameter to customize fault levels.
Option: Function:
[0] O Use [0] O 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
overcurrent incidents, this hardware
protection cannot be overruled.
[3] Trip lock
[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).
