Hello All,

Does any one out there know the PC50 mill main spindle drive card. I have a PC50 mill and have used it on and off for 10 years. Has worked fine until recently when the spindle stops and it reports Error 6013 main spindle not ready, I have replaced the 6 transistors on the spindle drive board but the spindle starts and then stops showing same error. Is there any thing else on the board or any other reason that can cause this. I have tried to contact Emco Austria and am waiting but am not hopeful of any help from there as it is an old machine (1995). I have seen mention of voltage issues and thermal issues on the drive board. I am now going to check voltages to see if the power supply is working correctly. Any help would be greatly appreciated.
