Drive Overload 2 (Ambient Temperature)

What does OL2 mean?

An OL2 fault indicates that the drive's internal overload protection level has been automatically reduced because the ambient temperature around the drive exceeds its specified rating, as configured in L8-12. This protects the drive's output power components from overheating under high load conditions. Continuous operation in an overly warm environment can lead to component degradation and drive failure.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   If applicable, ensure the drive is not subjected to direct sunlight or external heat sources.

2. 4

   Verify that parameter L8-12 (Ambient Temperature Setting) accurately reflects the installation environment's conditions.
