Alarm: 122 REGEN OVERHEAT
Haas Alarm Description:
The regenerative load temperature is above a safe limit. This alarm will turn off the servos, spindle drive, coolant pump, and tool changer. One common cause of this overheat condition is an input line voltage too high. If this condition persists, an automatic shutdown will begin after the interval specified by Parameter 297. It can also be caused by a high start/stop duty cycle of spindle.
