Alarm: 674 TT or B SERVO OVERLOAD – Haas Mill
Haas Alarm Description:
Excessive load on TT or B-axis motor. This can occur if the load on the motor over a period of several seconds or even minutes is large enough to exceed the continuous rating of the motor. The servos will be turned off when this occurs. This can be caused by running into the mechanical stops or by a very high load on the motors. If this alarm occurs on a machine with a VF-SS type tool changer, the most likely cause is a tool over 4 pounds not identified as ‘heavy’ in the tool table.
