Overload Advance Notice Signal [OL]
When the output current exceeds a preset value,
the [OL] terminal signal turns on.
The parameter C21 sets the overload threshold.
The overload detection circuit operates during powered
motor operation and during regenerative braking.
The output circuits use relay output,
and are active low.

OL
Overload advance
notice signal
ON
when output current is more than the set threshold
for the overload signal.
OFF
when output current is less than the set threshold
for the overload signal.
Valid for inputs:
C13, C14, C15,C16, C17, C21
Required setting
3
Notes:
•The default value is 100%.
To change the level from the default,
set C21 (overload level).
•The accuracy of this function is the same
as the function of the output current monitor on the
[FM] terminal
•Output terminal RN0-RN1 is a relay contact a.
In case of contact b, setup C16.
•Output terminal RN1-RN2 is a relay contact a.
In case of contact b, setup C17.
