Fanuc Alarm 3: Too Many Digits Error Fanus Control Model: Fanuc 0i, 16i/18i, and 21i/31i , 30i/31i/32i/0i-MODEL B Description Entering more digits than allowed in a program. Using non-standard digits in a G-code command for an X, Y, Z position or a speed value. This error usually indicates human error or a problem with the…
Fanuc Alarm PS017 ILLEGAL MODE FOR GOTO/WHILE/DO Fanus Control Model: 10/11/12/15/15i Description This alarm appears when the control system has difficulty executing these macro statements such as GOTO, WHILE, or DO. Does your CNC controller accept these specific commands or is there a fundamental error in the program logic that violates the prevailing rules of…
The Fanuc SV040 alarm is a servo-related error that indicates a N-th Axis Overload. This means the CNC system has detected that the motor is drawing too much current or is working too hard to maintain its position or movement, potentially leading to overheating. Common Causes The SV040 alarm can be triggered by either mechanical…
A Fanuc Alarm 402 is a common but critical error that indicates a Servo Alarm: SV Overload. Essentially, the CNC controller has detected that the electrical current being drawn by a specific axis motor is exceeding its rated capacity for too long. The system triggers this alarm as a protective measure to prevent the motor…
In the world of CNC machining, encountering a FANUC 401 Alarm can bring production to a grinding halt. This specific error is one of the most common—yet occasionally frustrating—faults found in FANUC Alpha and Beta series drive systems. Specifically, the 401 alarm stands for “V-Ready Off.” In simpler terms, the CNC control is expecting the…
