Fan fault output signal (FAN)
• A cooling fan operates at power ON of the converter unit. If the fan stops at this time, fan operation is regarded as faulty,
Fan alarm
(FN) is displayed on the operation panel, and the Fan fault output (FAN) and Alarm (LF) signals are output.
• To assign the FAN signal to the terminal, set "25 (positive logic) or 125 (negative logic)" in one of Pr.190 to Pr.195 (Output
terminal function selection). To assign the LF signal, set "98 (positive logic) or 198 (negative logic)".
Cooling fan operation command signal (Y206)
• The Cooling fan operation command (Y206) signal can be output when the converter unit cooling fan meets the conditions
for running. The function can be used when the fan installed on the enclosure is synchronized with the converter unit
cooling fan.
• Y206 signal indicates the operating command condition of the converter unit cooling fan depending on the power supply
ON/OFF. 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 any of Pr.190 to Pr.195 (Output terminal
function selection) to assign the function to the output terminal.
NOTE
• Changing the terminal assignment using Pr.190 to Pr.195 (Output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.

• The RDA and RDB signals are initially assigned to terminals
RDA and RDB respectively. By setting "11" for the RDA signal
or "111" for the RDB signal in either Pr.190 to Pr.195 (Output
terminal function selection) , the signals can be assigned to
other terminals.
• When the Converter reset (RES) signal is input to the
converter unit, the Inverter reset (RSO) signal is output to the
inverter.
• The RSO signal is assigned to terminal RSO in the initial
status. The RSO signal can also be assigned to other terminals
by setting "209 (positive logic) or 309 (negative logic)" in any of
Pr.190 to Pr.195 (Output terminal function selection).
