 Motor overload early warning signal -- OL
The OL signal is used to detect a symptom of an overload condition (alarm code
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 OL (data = 7) to any of the digital output terminals.
 Current detected and Current detected 2 signals -- ID and ID2
When the inverter output current has exceeded the level specified by E34 or E37 and it
continues longer than the period specified by E35 or E38, the ID or ID2 signal turns ON,
respectively. When the output current drops below 90% of the rated operation level, the ID or
ID2 turns OFF. (Minimum width of the output signal: 100 ms)
To utilize this feature, you need to assign ID (data = 37) or ID2 (data = 38) to any of digital
output terminals.
