I have a rotary phase converter rated at 5 hp running a Bridgeport Series 1 cnc. The spindle motor is 2 hp. The manufactured leg of the RPC is 275V and the other two are 242V. I'm afraid I will blow out transistors in the drives unless I can drop the input voltage or otherwise drop the drive motor voltage. These are open circuit voltages and when hooked up, will be somewhat lower.
Is there some easy solution to this? Thanks. cnc1000 :drowning:
