Hi PinguS, I have a FANUC OM-C and a Nikken 150 rotary table. We have everything set up and I have set most of the parameters according to their logic values (I don't have the original 4th axis parameters).

The system throws alarms at me (Servo alarm 401 and servo parametrs) I could not figure out what is missing to activate the rotary. When you activated your 4th axis, was there a particular parameter that need o be set in order to power up the drive. I always get VRDY alarm. The A axis is dislayed and even the encoder works and shows movement when I drive it manually. But the servo does not want to get into power mode.
