Heatsink Fan
All drive ratings include an in-built heatsink fan to aid cooling, the fan automatically turns on when the heatsink temperature reaches 45°C / 113F.
The fan can be set to either automatically turn on when the drive reaches 45°C or when the drive stops running and the drive temperature has reached 45°C.
To control the heatsink fan use parameters P11-14 and P11-15 to specify when the fan should come on and customize how long it should run for.
While in Rescue Mode due to the nature of the reduce power to the drive additional conditions need to be met for the fan to turn on.
The table below specifies the conditions for the heatsink fan to operate while in Rescue Mode.
Conditions | Comments |
|---|---|
IGBT Temperature (P0-48) ≥ 45°C | This is the turn on temperature for the Heatsink fan. This is the same as mains mode. |
Rescue Mode Input Closed | Depending on your selected Macro the Digital Input assigned with the function 'Rescue Mode' must be closed so Rescue Mode is active. You can check that status of Rescue Mode using P7-15 or check the status of the Digital Input using P0-01/P0-02 depending on the selected input. |
24Vdc Supplied to Control terminals | If the control terminals do not have 24Vdc externally supplied then the fan will not come on even if P0-48 ≥ 45°C. In addition if 24Vdc is not supplied to the drive (only powered via USB-C or RJ45 then P0-48 will not update. |

Sets how the drive fan should operate when the turn on conditions are reached.
Setting | Function |
|---|---|
0 | Fan controlled by internal temperature measurement regardless of if drive is running or not and P11-15 has no effect. When P0-48 reaches 45°C then fan will turn on and stay on until the temperature drops below 40°C. |
1 | Fan only runs for for time set in P11-15 only when P0-48 is above 45°C. |
This parameter defines the fan run time after the drive has stopped running when the temperature in P0-48 reaches 45°C.
Parameter P0-55 displays the total operating time of the drive Heatsink fans. The first value shown is the number of hours. Pressing the Up key will display the minutes and seconds.
