Please help I recently purchased my very first robot. I was very exited when I got it specially since I thought I had gotten a great deal. The problem came when I went to start it I turned on the power and everything seemed to be good until I tried to turn on the servos. After a few seconds of pressing the servo on button I got alarm code 5390. What can be causing that? Unfortunately I did not get any documents with the robot to help me solve the problem. Any help will be greatly appreciated.

Congrats. Hope it's the start of happy relationship. Moving robots and controllers tend to loosen things up that may not have moved in many years. I would power down and systematically make sure every connector and board in the controller is seated properly. Look over the cables on the robot and make sure nothing is pinched or smashed during shipping. The anacondas (black flex wire conduits between the robot & controller) should not be flattened. Make sure all the grounds are properly connected. Make sure the breakers on the side of the servo amps are up. Do you have manuals? Which robot do you have? Attached is the error code for your MRC.

Alarm 5390 is when the servo system is not ready. The most common time this comes up is if you press the servo on button on the panel or pendant but don't have the deadman pulled in (in teach mode).
Is your MRC deadman or non deadman?
One thing to look at is the MTU board. The MTU board is green and has some ice cube relays and is normally just above the contactor. On the MTU board is a connector CN8. Non deadman MRC robots have a jumper in this connector. With deadman versions, the jumper is removed the deadman circuit is connected.

Thank you all for your advises I will try them and will update.

It also seems that on certain MRC you have to press the Teach Lock button...One of the F keys to get the servos on.......

Thank you Robodoc just like you said I looked on the MTU board connector CN8 and there was nothing plugged in there so I placed a jumper and that fixed my problem just to give me an other problem. My problem now is that when I tried to cycle the robot on play mode it gives me an external hold alarm and I did not get any external operation station with the robot. Is there a way to wire the robot so that it can be run with out an external operator station?

First, make sure there is +24 volts on screw #22 of the MRY01 card. This is one external hold.
Next look at the status of 4067 (external hold. If it's on you will have to look at the CIO to see what is making it come on.
