ABSTRACT:
The invention relates to a monitor system for a servo controller used in connection with servo motors utilized in multivarious machines, such as machine tools. In addition to detecting a servo system fault when the difference between the commanded position and the actual position exceeds a predetermined value, the system monitors several servo system parameters to distinguish between different causes of servo faults. Identifying the source of the fault leads to improved maintenance and decreased system down time when a fault occurs.
