The alarm 2018 is indicating there is a fault with the spindle motor or the drive. Check the spindle/motor is not jammed.
The alarm AL-06 is coming from the spindle motor drive, it's an over speed alarm, it says that the motor speed exceeds 115%.
However if the alarm is coming without the motor even running, when you power on, it's very likely you have a fault with the spindle motor drive. If that is the case it will need replacment or repair. You need to contact Tornos US for advice.
