Fanuc Alarm PS006: Illegal Use of Minus Sign Fanus Control Model: Series 0i (Model C, D, and F), Series 30i / 31i / 32i, Series 16i / 18i / 21i Description Minus Sign – is written in a place where it is not allowed. This alarm can sometimes be caused by a logical error in…
Fanuc Alarm PS058: S–COMMAND OUT OF RANGE Fanus Control Model: 0i-D/F series, 16i/18i/21i, and the 30i/31i/32i series. Description If a spindle speed is written in the program that exceeds the machine’s operating capacity, the system will immediately stop the operation and an alarm will appear on the screen. How to Fix Alarm Check the S…
Fanuc Alarm 14 CAN NOT COMMAND G95 Fanus Control Model: Fanuc 0 (0-M/0-T), 0i, and 16/18/21 series controls Description Technically, the G95 code tells the machine to cut per revolution, which is directly related to the spindle speed. The most common cause of this alarm is that the Spindle Digital Encoder is either not installed…
Two very important commands are used to eliminate sharp corners of a workpiece or give them a specific shape: Chamfer and Radius. Through these commands, you can round the corners according to the design or create a bevel. The advantage of this is that the workpiece will be safer to handle, its strength will increase,…
Fanuc Alarm PS123: Missing END Statement Fanus Control Model: Series 0i, 16i, 18i, 21i, and 30i/31i/32i controls Description When you forget to write END at the end of a program using commands like `WHILE` or `IF` in a macro program, the CNC system gets confused and generates an alarm. How to Fix Alarm Go into…
G28 is an important reference command in CNC machines. It returns the machine to its Home Reference Point. When a program finishes or a tool change is required, the G28 command moves all or selected axes (X, Y, Z) back to their original safe position. Operators also call this process a “zero return.” What is…
Fanuc Alarm PS449: Illegal Tool Life Data Fanus Control Model: Series 15 (Model A and B), Series 10 / 11 / 12 Description This alarm occurs when there is a technical error in the Tool Life Management data in the machine control system or the specified life limit for a particular tool in the system…
Fanuc Alarm PS900: G72.1 NESTING ERROR Fanus Control Model: Series 15i, 16i, 18i, 21i, and 30i/31i/32i Description This alarm appears when the “G72.1” (Subprogram Call for Figure Copy) command is used incorrectly in CNC programming. The main reason for this alarm is exceeding the “Nesting” limit, that is, when you call several subprograms consecutively within…
Fanuc Alarm PS891: ILLEGAL COMMAND G05 Fanus Control Model: Series 15 control (including Series 15-MA, 15-TA, 15-MF, and 15-TF). Description When the G05 command is written incorrectly in the program or the controller detects a technical error in the use of the G05 command. One reason for this alarm is that the G05 command is…
Fanuc Alarm PS067: G70–G73 IN FORBIDDEN MODE Fanus Control Model: Most commonly associated with Fanuc Series 0 (0-T/0-TF) and the Series 16/18/21 Description The control system receives a command in G70, G71, G72, or G73 that is incompatible with its specific mode. This problem usually occurs when you run these Canned Cycles in a sub-program…
Facing is the process of making the top surface of a workpiece perfectly smooth, straight and level. It is widely used in CNC machines. In this process, the cutting tool usually moves in the X and Y axes and cuts the material in a small depth (Z axis) to eliminate the uneven surface. Facing is…
G75 is an excellent CNC group cycle, one of the best advantages of which is that this command does not require repeated code writing, but rather contains complete logic in a single command. This code is a great way to save time, protect the tool, and achieve better quality. G75 is typically used for radial…
Fanuc Control Model: Fanuc 16i / 18i / 21i Series & 0i / 30i / 31i Series Official Alarm Description The number of tool groups to be set exceeds the maximum allowable value. (See parameter No. 6800 bit 0 and 1) Modify the program Common Causes This alarm is typically triggered when setting up tool…
The G72 Facing Cycle is an important programming command that is widely used in CNC lathes. This command smooths the surface of the workpiece by removing material to a certain depth. G72 is a very useful facing cycle, especially for circular profiles and medium-hard materials. It completes the facing operation by repeating the programmed tool…
Thread cutting on a CNC lathe is extremely important, and G76 is a multi-pass and widely used threading cycle.
