Jim opened the electrical cabinet and looked at the . On the small seven-segment LED display, he saw a glowing "8" . In Fanuc language: 8 = High current in the first axis (L-axis). 9 = High current in the second axis (M-axis). A = High current in the third axis (N-axis). fanuc 414 servo alarm z axis detect error
View Diagnostic screen No. 200 . If bit #4 (HCA) is 1, it indicates an Abnormal Current alarm. If bit #6 (LV) is 1, the voltage is too low. : A blown transistor module (IPM) in the
