I have an Arrow 1000 with the black Cincinnati Milacron drives. The problem happens when I turn the Spidle on at rpm range of 3000 or higher. I get the Alarm: Axes Drive ready signal missing and the machines power to the drives are not enabled any more. There are no faults shown on any of the drives. If I enable the power again and tell it to run 1000 RPM, the spindle will run. So basically I cannot run high RPM without the machine tripping out. I have swapped out the power supply and spindle drive with known good drives and it is the same results.
Has anyone had this same issue or know of a component that would cause this problem?
