When you Init you lose all the previous Field adjustable parameters, such as,encoder ppr, motor rpm,and others. If the Drive Board is now indeed good he can try running on just the MSU Board. this will let him know if those Boards are good. Pull out the CPU, make sure the Safety circuit and door locks are made up, also the mgs input on the Miprom I card rack.Put the car on inspect and you should run on construction speed. That is how they do it on install. It was not a good idea to send a good CPU Board to a Motor Shop. It is a worse idea to take advice from a Motor Shop on how to make an Elevator run. The tool should still show him what the fault Log is. Also make sure the Drve Board jumper at j14 is in the 1-2 position, if it isn't you won't be able to change any Drive Parameters. your friend could be in for a long day.
