Need help with one of our Sabres in shop, was working fine last week, went to fire it up and immediately gets an alarm 39-53, if you keep trying to power up the machine you will get 39-6 which says drives not ready. Since we have a few of these machines we swapped all the drives including spindle and power supply with no luck. The only reason we started swapping all the drives is because we do not get a red led on any the Kollmorgen drives?? I have a new signal cable that I have tried on all 3 drive motors and we get the same error, I do not have a new power cable to try for the motors though so not sure where to go right now. Can anyone help?
