Auxiliary fan missing

What does A582 mean?

An auxiliary cooling fan, typically connected to the control board, is either stuck, disconnected, or has failed. This compromises the supplemental cooling for the drive's internal components, potentially leading to overheating warnings or faults if the thermal conditions worsen, especially in high ambient temperatures or loads.

• Auxiliary cooling fan connector is loose or disconnected from the control board.
• Fan motor or bearings are seized, preventing the fan from rotating freely.
• Fan's tachometer (speed feedback) signal line is open-circuited or shorted, causing the drive to believe the fan is not running.
• Drive's internal fan monitoring circuit has failed or is miscalibrated.
• Accumulated dust and debris are obstructing fan blades, leading to stalling or reduced speed.

Click steps to track your progress.

1. 1

   Power down the drive and visually inspect the auxiliary fan for physical damage or obstructions.

2. 2

   Gently try to rotate the fan blades by hand to check for freedom of movement; remove any detected obstructions.

3. 3

   Verify the fan's power and tachometer cable is securely connected to the designated connector on the control board.

4. 4

   Measure the supply voltage to the fan connector (e.g., 24VDC) to ensure the control board is providing power.

5. 5

   If the fan does not spin when power is applied, or if the tachometer signal is absent (refer to wiring diagram for specific pins), replace the auxiliary cooling fan assembly.
