Guita,

Alarm 926 is an alarm of FSSB ??? If yes, some reasons causes that:

1) Power fault in a servo amplifier
2) If power voltage supply drops
3) If 5VCC of the pulse coder is ground.

926 FSSB ALARM : Replace the axis control card.

Al-24 shown on SPM is EMG state. when machine ready this alarm is gone.
