The
OL
signal is used to detect a symptom of an overload condition (alarm code
0l1
) of the
motor so that the user can take an appropriate action before the alarm actually happens.
The
OL
signal turns ON when the inverter output current has exceeded the level specified by
E34. In typical cases, set E34 data to 80 to 90% against F11 data (Electronic thermal overload
protection for motor 1, Overload detection level). Specify also the thermal characteristics of
the motor with F10 (Select motor characteristics) and F12 (Thermal time constant). To utilize
this feature, you need to assign
