Fan control

Excessive temperature inside the inverter cover can reduce the life of the inverter. To avoid excessive
temperature, two fans are driven by the control electronics. When the compressor is off, the fans are off too.
When the compressor is operating, the fans are turned on and off (the duty cycle is proportional to the square
of the inverter load factor). In addition, there is a temperature sensor on the REG card: when the measured
temperature exceeds a given value, the fans are continuously turned on until the measured temperature falls
below the threshold (with hysteresis).
The inverter is provided with a software hour counter for the fans (parameters N86), which counts the actual
operating hours of the fans. The hour counter can be reset by setting C45 to 1.
The Fans are connected to PWR-CN14 and PWR-CN15 connectors of the PWR card.
