170 Phase Loss L1-L2 Problem with incoming line voltage between legs L1 and L2. This usually indicates that there
was a transient loss of input power to the machine.
171 Phase Loss L2-L3 Problem with incoming line voltage between legs L2 and L3.
172 Phase Loss L3-L1 Problem with incoming line voltage between legs L3 and L1.
173 Spindle Ref The Z channel pulse from the spindle encoder is missing for hard tapping
Signal Missing synchronization.
174 Tool Load Exceeded The tool load monitor option is selected and the maximum load for a tool
was exceeded in a feed. This alarm can only occur if the tool load monitor function is installed
