6.1 Schedule of Function Parameters 6.1 Schedule of Function Parameters
F4.13 Overload Pre-alarm Level Setting range: 20~120% Default value: 100%
F4.14 Overload Pre-alarm Action Time Setting range: 0.0~15.0s Default value: 1.0s
Overload pre-alarm level defines the current threshold of overload pre-alarm action.
Its setting range is the percentage in respect to rated current. Generally, the overload
pre-alarm level should be set lower than overload protection level.
If the output current reaches the overload pre-alarm level and its durative level
exceeds the set time of overload pre-alarm action, then overload pre-alarm acts, as
shown in Fig. 6-18.

F4.15 Counter reset setting Setting range: detection value ~60000 Default value: 1
F4.16 Counter detection value setting Setting range: 0~reset value Default value: 1
This parameter group stipulates counting work of the counter. The pulse of counter
is input by the external terminal X6. When the counting value for external pulse
reaches the value set by F4.15, the corresponding multi-function export terminal
(counter reset signal output) will outlet an effective cycle signal with width of
500ms and then clear the counter value.
When the counting value reaches the value set by F4.16, the corresponding multi-
function export terminal (counter detection signal output) will outlet an effective
cycle signal. If the counter continues to count and the value surpasses the value set
by the parameter F4.16, this effective signal will be cancelled when the counter is
cleared.
In Fig.6-15, Y1 is set to be a reset signal, Y2 is set to be a
detection signal output, F4.15 is set to 8 and F4.16 is set to 5.
