Hi all, I would like to ask some one who expert about how to check Fanuc Servo Alpha Series, The problem is 401 Servo ready off (VRDY). Some time PSM, SPM and SVM defective, How can I know which one defective? Some one told me that they need dummy connector for this problem? Any one know how easy way to check this problem? I do now just try to exchange all units. Some time I don't have no spare. If some one know email me at k_amnaj@yahoo.com Thank you  |

| please find alpha series data/manual in gefanuc website, i don't remember the address. just write on google. for this case sound like your drive no work, usually 24v input none, fuse broken, or no voltage on pcb (24v,15v,5v) please check your led indicator, if off, i think your 5V none. good luck |
