Figure 5-72 Overload Detection Configuration
One's place of FL.04: overload detection mode
0: the detection is done as long as the drive is operating.
1: the detection is done only when the drive works at
constant speed.
Ten's place of FL.04: action mode
0: The overload is ignored, no alarm.
1: During "Overload Alarm Effective Period", the drive will
alarm and stop operation. The "Overload Alarm Effective
Period" means the drive's operating current has exceeds
FL.05 and whose duration has exceed overload alarm delay
(FL.06) .
Hundred's place of FL.04: reference current
0: the overload detection threshold (FL.05) is set based on
motor's rated current. Fault code E014.
1: the overload detection threshold (FL.05) is set based on
drive's rated current. Fault code E013.
FL.05 defines the threshold for overload alarm. It is a
percentage of either drive's or motor's rated current. Refer to
setting of the hundred's place of FL.04. The setting of FL.05
also relates to the type of the drive. Please refer the table
below:
Type Setting Range
G 20.0%~180.0%
P 20.0%~130.0%

Note
1. Overload detection threshold should be lower than the overload
protection threshold;
2. During the overload alarm delay period, if the drive's current
becomes lower than overload detection threshold, no alarm will be
triggered.

FL.08 Freq.decrease rate rate during
current limiting
FL.09 Action mode of auto current
limiting
Auto current limiting function is used to limit the load current
under the preset current in real time to avoid trip due to
over-current. This function is especially useful for the
applications of larger load inertia or sharp change of load.
FL.07 defines the threshold for current limiting. Its setting is
a percentage of drive's rated current Ie.
Type Setting Range
G 20.0%~180.0%
P 20.0%~130.0%
FL.08 defines the decreasing rate of output frequency when
the drive is in auto current limiting status.
If FL.08 is set too small, overload fault may occur. If FL.08 is
set too big, the drive may be in energy generation status for
long time that may result in overvoltage protection.
The action mode of auto current limiting function is decided
by FL.09.
FL.09＝0: disabled;
FL.09＝1: auto current limiting is effective during
acceleration or deceleration but ineffective at constant speed,
no silencing function;
FL.09＝2: effective all the time, no silencing function;
FL.09＝3: auto current limiting is effective during
acceleration or deceleration but ineffective at constant speed,
with silencing function;
FL.09＝4: effective all the time, with silencing function.
Because the output frequency might change during current
limiting, the function should be used for applications that
require constant speed and stable frequency output.
FL.10 Auto reset times
FL.11 Auto reset interval
Auto Reset function can reset a fault according to the preset
FL.10 and FL.11. If FL.10 is set to 0, auto reset is disabled.
Protective action will be taken if a fault occurs.
Note
Overcurrent protection and external fault (E015) cannot be reset
automatically.
During the reset interval, the drive's stops operation and restarts
on the fly when the reset is finished.
Be careful when using auto-reset function, otherwise human injure
or material loss may occur.
FL.12 Protective action mode 1
FL.13 Protective action mode 2
The fault alarm and protective action can be prohibited by
setting FL.12 and FL.13, so that the drive can continue
working.
