FANUC SRAM Backup Procedures
The first step used to prepare FANUC memory card, then input into the slot near the screen, Operation : Turn the power on by simultaneously pressing the two soft keys at the right end you can see in the picture below
The second step you press the down button select “7.SRAM DATA UTILITY”>> select>> Yes it will display the screen as shown below
The third step you select “1. BACKUP SRAM (CNC => MEMORY CARD) SELECT YES then see the picture below
Wait until a “SRAM BACKUP COMPLETE”
Then press SELECT again select the number “1. END “select YES
Similarly, FANUC sram backup procedure on CNC machine may be useful.

Solve Problems / Alarm Pulse Coder on CNC Machining
Before you fix the alarm pulse coder must know first what the cause of the alarm pulse coder? That caused the alarm pulse coder is the first error pulse coder itself. If that is you have to change. Cable, check the condition of the cable with multitester whether there is a break. Drive (SVM) faulty. Parameter settings are not right but this is rare, and an excessive load on the axis.
For a detailed explanation for the alarm pulse coder on a machine CNC machining. Check the cable connections if contaminated with coolant. It often happens coolant into the connector due to telescopic a leak. Spray with a spray gun for cleaning the coolant air. Also check the pin is in the correct position. If all alarms have been checked still replace it with a new pulse coder.
If still alarm also may drive / SVM trouble. Replace drive / SVM you. At the time wanted to change the pulse coder must be careful not the hammer, then will cause damage. To find the problem that happens you can help the operator. Ask if the alarm came when the axis moves? What is the current axis position of silence? What is the specific coordinates? If the alarm in this position usually your cable problems.
To repair the zero pulse coder position is changed then you must reset the settings. In order for the zero position is not far away with the old one better at the time of going improvement Condition zero position for when the repair is completed you can simply reset the settings without looking back to the zero position.
