Setting 4D: oH Pre-Alarm Time Limit
The output terminal closes when the drive is reducing the speed due to a drive overheat alarm (L8-03 = 4) and the overheat
alarm has not disappeared after 10 frequency reduction operation cycles. Refer to L8-03: Overheat Pre-Alarm Operation
Selection on page 117 for a more detailed description.
