You’re going to have to do an init. In most cases it will run with default parameters.

If this is part of a group, or a duplex you can look at those parameters. If you init the drive, you will lose all the field programmable parameters. The f mismatch is saying that one or more of the field programmable parameters stored in the drive, do not match the the the ones stored in the Miprom. you should check them one by one. parameters such as motor RPM's, car speed, armature amps, the list goes on.Check these in MSU adjust, and drive adjust screens.

Hey dripcan, make sure you check logic voltage. Very important to have 4.8-5.2 vdc. This is extremely crucial with that system. I could see the power supply going slightly out of whack after sitting so long. I have had wierd things like a blank screen happen and found low voltage on the logic end being the issue. If that's not the confirmed issue via voltage check it is okay to initiate the drive versus reinitiating the drive.
