►
Control the On/ Off of the cooling fan to cool the Inverter heatsink.
►
When it is set to 0:
- Cooling fan begins to operate when power ON.
- Cooling fan is stopped when inverter main circuit voltage becomes low voltage due to
power off.
►
When it is set to 1:
- Cooling fan begins to operate when power is turned ON with operating command ON.
- Cooling fan is stopped when operating command is turned Off with inverter output
shut off.
- Cooling fan keeps operating when heat sink temperature exceeds a certain limit
regardless of operating command.
- Used when frequent Run/Stop or quite stop is required. This may make the cooling
fan life longer.
►
When it is set to 2:
- The cooling fan is not active even when power is supplied to the inverter and an
operating command is input. However, if the temperature of the inverter heat sink is
higher than a certain degree, cooling fan is active.
