代碼 SRVO-148: HCAL(CNV) alarm (G:%d A:%d)
問題描述與安全警告
Fanuc R-30i Series Robot Controller 觸發了嚴重的 HCAL(CNV) alarm (G:%d A:%d) 警報。需要由合格的操作員或維修技師立即處理，以防止在製造週期中對設備造成二次損壞或導致零件報廢。在接觸電氣控制箱之前，請務必確保遵循標準安全和停機掛牌 (LOTO) 程序。
官方故障排除步驟
Cause: The current in the main power circuit of the servo amplifier exceeded specification. Remedy: Disconnect the motor power wires from the servo amplifier and turn on power. If an HCAL occurs, replace the transistor module or servo amplifier. Measure the resistance between GND and U, V, W individually on the cable terminals. If shorted, determine if the cable or motor is bad. Check the resistance between U-V, V-W, and W-U using a measuring instrument sensitive enough to detect small resistances at the cable terminations. If the resistances are the same, replace the servo amplifier. If the resistances are different, determine if the cable or motor is bad. If the problem persists, replace the SIF module on the axis control for the defective axis.
