Well i'm back with another question. I had my H400 all sorted and was programming ready to make some parts when it shut down on Estop. I restarted it and had a 30 no signal error and all the axis drives have an overtravel error. The spindle control had an E7 error and all the drives have a 21 error on them. Any ideas? I can't seem to find much info on the drives on the MEAU site and I don't have much on the spindle controller.
Over to the Mazak gurus
Well problem is solved. I've done a lot of thinking while doing other things and thought why am I getting + and- overtravel errors on all drives and no signal.remembered that the machine has linear encoders so wondered if they had their own power supply. Sure enough opened up the end cabinet where the drives for the encoders were installed and found a dead power supply. Attached a variable supply to try it and away it went. It took me a while but got there in the end. Now to rewrite the programs and get a new power supply then finally make some chips.
