What causes an E-Flex drive to trip on overheating fault OHF?
Resolution:
Check the heat sink cooling fans to see if they are running. If they are not running remove the fan connector and check to see if you have voltage on the terminals. If you have good voltage then the heat sink cooling fans are bad. If you don't have voltage on the terminals you may have a bad power board and or drive.
To check the thermal sensor you can monitor the drives thermal temp % in Menu 1.2 monitoring. If the thermal % is jumping around erratic you may have a bad thermal sensor.
These drives have already been discontinued. Please reach out to us for information about replacement options.
