Yes I agree. Try calling Mitsubishi. They will help you through the alarms unless you can list them for us. If you have homed out the machine and it will not move it sounds like you do not have the soft limits set. If I remember correctly there are two sets of them, one set in the user parameter area and one set in the machine parameter area.
What is the spindle alarm?
