Drive’s Cooling Fan Fault

What does FAN mean?

A fault with the Drive's internal cooling fan has been detected, leading to the activation of Drive overload protection due to excessive internal thermal value. This typically occurs when the fan stops running and the Drive continues operating under load, causing heat to build up. Unresolved, this will lead to repeated overheating faults and potential damage to the Drive's power components.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Replace the cooling fan unit within the Drive, ensuring it is the correct specification and installed properly.

2. 4

   Verify parameter L8-32 (Cooling Fan Fault Detection) is set to 1 if automatic fan fault detection is desired.
