Fig. FA-3 Off Load Detection
Notice
With the setting of parameter FA.12 and
FA.13, when the output current of the
driver is higher than overload pre-alarm
level (FA.12), the driver will send pre-alarm
signal after delay time (FA.13), i.e. the
control panel will display "A-09".
Overload pre-alarm function is mainly used
for monitoring overload condition before
overload protection action. Overload pre-
alarm level defines the current threshold of
FA.12

on model
This parameter defines the delay time from
the time when the output current of VFD is
higher than the overload pre-alarm level
(FA.12) to the time when overload pre-alarm
signal is sent.

4.2 Detailed Function Description
0: o󽗈 load detection disabled
O󽗈 load detection level (FA.10) de󽗉nes the
current threshold of o󽗈 load action, and the
set value is the percentage relative to rated
current of the VFD.
O󽗈 load time (FA.10) de󽗉nes the lasting time
that the driver output current is lower than
o󽗈 load detection level (FA.11) continuously,
after which the o󽗈 load signal is sent.
Off load status valid means that the
operating current of the driver is lower than
o󽗈 load detection level and the lasting time
exceeds o󽗈 load detection time.
