• When P.245=1 or 11, turning on the power will turn on the fan. When the power is turned off,
the fan will be off, too.
• When P.245=2 or 12, the fan will be turned on if the temperature of the heat sink is higher
than 40℃. When the power is turned off, the fan will be turned off, too.
• When P.245=3 or 13, the fan will be turned on when the temperature of the heat sink is
higher than 60℃. When the temperature of the heat sink is lower than 40℃, the fan will be
turned off.
Note: please refer to the parameter P.40, P.85, P.129, P.130.

<Setting>
• P.246 is used to determine the ratio between the maximum output voltage and the input
voltage. The users can use this parameter to obtain an output voltage that is higher than
the input voltage. But the output voltage waveform at this point will generate distortion and
contain assorted harmonics. It may also increase the motor torque harmonics and noises.
