flowing through the servo amplifier or motor. It is often triggered when the motor is not compatible with the driver or if there are severe electrical issues in the power circuit. Tri Star CNC Services Alarm Report: SV0366 Alarm Name SV0366: Abnormal Current Fault Source Servo Amplifier, Servo Motor, or Feedback Cables Primary Meaning
: Vibration in the motor can cause it to draw excessive current, or the power leads may be incorrectly connected. Mechanical Load
This alarm specifically relates to the "Hard Stop" mechanism (often used on turning centers for bar pulling or C-axis clamping). The control has issued a command to clamp or lock the spindle/hard stop, but the system did not receive the confirmation signal (Logic "1") within the specified wait time. Essentially, the machine tried to lock, but didn't "feel" or "see" the lock happen. fanuc 366 alarm
If you want, I can:
O1000 #100 = 5 * [ 2 + 3 M30
The , commonly labeled as "n AXIS: PULSE MISS (INT)" , indicates a pulse error occurring within the motor's built-in pulse encoder . This fault specifically suggests that the digital servo software has detected a loss of pulse data integrity or invalid data from the encoder. Core Causes
: Frequent axis movement can fray or loosen the encoder cables, especially at the connection points. flowing through the servo amplifier or motor
Ensure the NC power and Servo power (AD converter) are not being interrupted abruptly, causing data loss.
