The fi
ure below shows the continuous permis-
sible current with F10 (electronic thermal O/L re-
la
[Select]) = 2. 100% of the continuous
permissible current is the current value set with
function F11 (electronic thermal O/L rela
[Lev-
el]).
The
raph below shows the electronic thermal
O/L rela
operatin
characteristics. Output cur-
rent values for the electronic thermal operatin
levels (values set with function F11) are plotted
horizontall
and operatin
times for output cur-
rent are plotted verticall
.
This
raph is for F10 = 1 with the base frequenc
of 50Hz. The characteristics for output frequen-
cies exceedin
the base frequenc
are the same
as the characteristics for the base frequenc
.
When function F10 is set to 2, the characteristics
are alwa
s the same as those for the base fre-
quenc
. The operatin
time with output current
of 150% can be adjusted b
usin
function F12
(electronic thermal O/L rela
(thermal time con-

This function sets the operatin
time of the electronic thermal O/L
rela
when the current that is
150% of the operation level flows.
0.5 to 10.0 min. can be set
(in 0.1 min. step).
