Alarm 88 on the Alpha i spindle amplifier indicates a failure of the internal cooling fan.

When the spindle amplifier faults out for an internal fan alarm, it does so in two stages.  When it first detects a fan problem, the amplifier goes into a warning mode, and if the fan issue hasn't corrected within one minute, it goes into an alarm state.

The word "FAN" flashes in the status LED when the CNC detects that a spindle amplifier is in the warning state.

While the spindle amplifier is in the warning state, the servo amplifiers are still powered up and able to move the machine around.  

The SP 9088 alarm indicates that the amplifier is in the alarm state and all of the amplifier units immediately become NOT READY.

Look for the unit that is displaying a 88.

The external cooling fans can be removed and replaced as shown below
