Starting Contact Signal (FR)
The starting contact signal is output for the duration that the FW terminal or RV terminal is being input.
The inverter will stop if the FW and R
V terminals are input simultaneously
, and the FR terminal (187:
Starting contact signal) turns OFF.

Cooling Fin Overheat Warning (OHF)
This function monitors the temperature of the cooling fin of the inverter and turns the cooling fin over-
heat warning signal ON/OFF according to the conditions below.
•
When the cooling fin overheat warning signal is OFF
The cooling fin overheat warning signal turns ON when the cooling fin temperature is overheat trip
temperature - 5°C or above.
• When the cooling fin overheat warning signal is ON
The cooling fin overheat warning signal turns OFF when the cooling fin temperature is overheat trip
temperature - 8°C or below.
• When the cooling fin temperature is the overheat trip temperature or above, cooling fin overheat oc-
curs (alarm code: 11).

Low Current Signal (LOC)
This Light load detection signal (LOC) is output when the output current falls to or below 1st Overload
Early Warning Detection Level (3005Hex-26Hex).
At Low Current Detection Condition Selection (LOC) (301FHex-55Hex), select whether to have the in-
verter output this signal constantly during run or only during constant speed operation.
