ACS580 drives are fitted with variable-speed cooling air fans. The cooling air must be free from corrosive materials and not exceed the maximum ambient temperature of 40 C for frames R1 to R9 (50 C with derating). The speed-controlled fans cool the drive only when needed, which reduces overall noise level and energy consumption.
