Fans
In a speed-controlled fan, the speed of the fan matches the cooling needs. This increases
the life span of the fan.
In a speed-controlled fan, the speed of the fan matches the cooling needs. This increases
the life span of the fan.
Main fans are speed controlled. When the drive is stopped, the main fan is kept running
at low speed to cool the control board. IP21 (UL Type 1) frames R6…R8 and all IP55
(UL Type 12) frames have auxiliary fans that are not speed controlled and run all the
time when the control board is powered.
Replacement fans are available from the manufacturer. Do not use other than specified
spare parts.
