This signal is output when the output current falls to or below the Low Current Detection Level (CE102).
Assign the output terminal function 032 [OHF] cooling fin heating prewarning signal to one of [CC-01] to
[CC-07] that corresponds to the output terminal and output the signal.
You can understand the state from the signal before the temperature error [E021] is generated by the
cooling fin heating prewarning level function.
Precautions for Correct Use
The temperature error [E021] is generated when the cooling fin temperature exceeds 120°C.
