Parameter L8-02 specifies the detection temperature in
S
C for the Inverter overheat (OH) pre-alarm
function. An overheat pre-alarm occurs when the temperature of the cooling fins reaches this level.
•
Parameter L8-03 specifies the processing that will be performed when an overheat pre-alarm occurs.
