1. You did not specify the drive model. We cannot read your mind.

2. Why would not you get the drive manual and find the explanation of this error?

3. This may be not an error, but a specific mode of the drive display. (F may stand for function).

Generally the F28 is fieldbus timeout (this may be caused by a momentary loss in the fieldbus comms), to reset this type of fault a power cycle of the drive is required.

this is assuming you are using a movidrive inverter
