operation
 Cooling fan always ON (Pr.244 = "0")
• When Pr.244 = "0", the cooling fan operates at power ON. If the fan stops at this time, the inverter finds that the fan
operation is faulty and "
output (FAN) signal and the Alarm (LF) signal are output.
• For the terminal used for the FAN signal output, set "25 (positive logic)" or "125 (negative logic)" in any of Pr.190 to Pr.196
(Output terminal function selection) and for LF signal, set "98 (positive logic)" or "198 (negative logic)".
 Cooling fan operation control (Pr.244 (P.H100) = "1" (initial value), "101 to
105")
• The cooling fan operation is controlled when Pr.244 = "1". When the inverter is running, the cooling fan operates constantly.
When the inverter is stopped, the cooling fan operates depending on the temperature of the inverter heat sink. If the fan
stops although it meets the conditions for running, fan operation is regarded as faulty, [FN] is displayed on the operation
panel, and the fan signal and LF signals are output.
• To prevent the cooling fan from turning ON and OFF repeatedly during frequent starts/stops (inching), the cooling fan stop
waiting time can be set. The waiting time when Pr.244 = "101 to 105" is Pr.244 - 100 (or 1 second, if the Pr.244 = "101").
 Cooling fan operation command (Y206) signal
• The Cooling fan operation command (Y206) signal can be output when the inverter cooling fan meets the conditions for
running. The function can be used when the fan installed on the enclosure is synchronized with the inverter cooling fan.
• The Y206 signal indicates the operating command condition of the inverter cooling fan depending on the power supply ON/
OFF or the Pr.244 settings. The signal does not indicate the actual operation of the cooling fan. (The signal is output even
if the cooling fan is stopped due to a fault.)
• To use the Y206 signal, set "206 (positive logic) or 306 (negative logic)" in one of Pr.190 to Pr.196 (Output terminal
function selection) to assign function to an output terminal.
