Haas Alarm: 992 AMPLIFIER OVER CURRENT – The amplifier has detected excessive current going to the motor. This can be caused by a stalled motor, a high motor load for a short duration, a spindle speed that is too low during a cut, a motor improperly wired or a faulty amplifier. Check the motor, and the programmed spindle speed and surface speed. Make sure the axis did not hit a hard stop. This can also be caused by a faulty amplifier.
