So close.....am882 driver blowing fuse

[Danielroyal25]

This is why I'm so confused by it. All the settings are identical on every drive and tried several times with new fuses and they have all blown. I can't see how the other 3 drives are fine but this one isn't. Will see i I have a slightly higher rated fuse and give it a go.

No don't go higher on the fuse else you risk damage. I'm currently setting up a machine with AM882 and running 1A fuse for safety while testing without blowing fuses so you have a problem some where Dan.

Go over all the wiring again and check connections. You will have a problem somewhere that isn't obvious.
I've built many control boxs now and still I get problems and just today I've spent 5 hours chasing an issue that turned out to be a simple 0v wire in wrong place so it will be something daft like this. Go over every thing with a fine tooth comb.

DONT UP RATE FUSES Whatever you do.

Dan I'm at home all day today(Sun) if you want to ring and funnly enough trying to finish off a machine and wrestling with control box's that don't want to play nice. Though hopefully I've beat this one into surrender.!! (Shit I've probably cursed my self now. .)

You didn't say in your first post that you had replaced the fuse several times otherwise I would had said something different.
If a fuse blows once sometimes it's bad luck, but twice indicates a problem and as others have said the last thing is to increase the fuse size. As Clive says try it with the motor disconnected. You could swap the motor from another drive, or swap the board with another board, the trouble there is you might end up with two faulty boards.
If you bought it in the UK you could probably send it back to the suppplier for testing.
