    Default 926 FSSB

    Getting 926 FSSB alarm when accelerating or decelerating the spindle only. 21iTA
    Machine is a two spindle Takisawa with a control on each side. Have switched drives, replaced PSU, swapped spindle amps, swapped servo amps, swapped sero module and swapped fiber cable between sides. Alarm still only happens on one side. FANUC has been out, and said to replace motor power cables. I have done that, but alarm still occurs.

    What does the spindle have to do with the FSSB? It doesn't even use the fiber optic cables!

    Because this happens when spindle is accelerating or decelerating sounds like the issues is power related. If the spindle power leads come in contact with the servo feedback cables this could induce electrical noise onto the cable and cause strange things to happen. Make sure that your power is stable and the phases are balance. Check your grounding a well.
