Tips and Tricks for Fanuc OT 900 Parameters Settings


What You Need to Know About Fanuc OT 900 Parameter List




Fanuc OT is a popular CNC controller that offers many features and options for CNC operators. One of these features is the ability to set and change various parameters that affect the machine's performance, functionality, and behavior. These parameters are stored in a special memory area called the 900 parameter list.




Fanuc ot 900 parameter list



The 900 parameter list contains many different types of parameters, such as communication parameters, option parameters, diagnostic parameters, program parameters, and offset parameters. Each parameter has a number and a value, which can be either binary (0 or 1) or decimal (0 to 9999). Some parameters can be changed by the operator using the PWE (parameter write enable) switch, while others are fixed by the manufacturer and cannot be modified.


In this article, we will explain how to access, view, edit, save, load, and delete the Fanuc OT 900 parameter list. We will also provide some examples of common parameters that you may want to change or check for your CNC machine. By the end of this article, you will have a better understanding of how to use the Fanuc OT 900 parameter list to optimize your CNC operations.


How to Access the Fanuc OT 900 Parameter List




To access the Fanuc OT 900 parameter list, you need to follow these steps:


  • Turn on the CNC machine and wait for it to initialize.



  • Press the SYSTEM key on the operator panel.



  • Select PARAM from the menu that appears on the screen.



  • Press the PAGE DOWN key until you see 900 PARAMETER on the screen.



  • Press the CURSOR DOWN key to scroll through the list of parameters.



  • Press the CURSOR RIGHT key to see the value of each parameter.



You can also use the ADDRESS and DATA keys to enter a specific parameter number and value directly.


How to Edit the Fanuc OT 900 Parameter List




To edit the Fanuc OT 900 parameter list, you need to follow these steps:


  • Make sure that the PWE switch on the back of the CNC machine is set to ON. This will allow you to write changes to the parameter memory.



  • Access the Fanuc OT 900 parameter list as explained above.



  • Select the parameter that you want to change using the cursor keys or by entering its number with the address key.



  • Enter the new value for the parameter using the data key or by typing it on the keyboard.



  • Press the INPUT key to confirm your change. You will see a message saying PWE ALARM on the screen. This means that your change has been registered but not saved yet.



  • To save your changes permanently, press RESET and then PWR OFF. This will turn off the CNC machine and store your changes in the parameter memory.



  • To cancel your changes without saving them, press CAN. This will return you to the previous screen without modifying any parameters.



Note: Some parameters may require you to restart the CNC machine after changing them for them to take effect. Some parameters may also affect other parameters or functions of the machine, so make sure you know what you are doing before changing them. Always refer to the manual or contact your manufacturer for more information on each parameter.


How to Save, Load, and Delete the Fanuc OT 900 Parameter List




Sometimes, you may want to save, load, or delete the entire Fanuc OT 900 parameter list for backup, restore, or troubleshooting purposes. To do this, you need to follow these steps:


To save the Fanuc OT 900 parameter list:




  • Make sure that you have a tape reader or a PC connected to your CNC machine via RS-232 port.



  • Select Tape Mode on your CNC machine by pressing Tape Mode Select Switch.



  • Select Punch Mode by pressing Punch Code Select Switch.



  • Select Tape Format ISO by pressing Tape Format Select Switch ISO/EOB.



  • Select All Memory Punch Mode by pressing All Memory Punch Mode Select Switch ON/OFF.



Select Edit Mode on your CNC machine by pressing Edit Mode Select Switch EDIT/MDI/AUTO/REF/H


To load the Fanuc OT 900 parameter list:




  • Make sure that you have a tape reader or a PC connected to your CNC machine via RS-232 port.



  • Select Tape Mode on your CNC machine by pressing Tape Mode Select Switch.



  • Select Read Mode by pressing Punch Code Select Switch.



  • Select Tape Format ISO by pressing Tape Format Select Switch ISO/EOB.



  • Select All Memory Read Mode by pressing All Memory Punch Mode Select Switch ON/OFF.



  • Select Edit Mode on your CNC machine by pressing Edit Mode Select Switch EDIT/MDI/AUTO/REF/H.



  • Press the INPUT key to start reading the parameter list from the tape or PC. You will see a message saying PWE ALARM on the screen. This means that the parameter list has been loaded but not saved yet.



  • To save the loaded parameter list permanently, press RESET and then PWR OFF. This will turn off the CNC machine and store the parameter list in the parameter memory.



  • To cancel the loading without saving it, press CAN. This will return you to the previous screen without modifying any parameters.



Note: Loading a new parameter list may overwrite some of your existing parameters or options, so make sure you have a backup of your original parameter list before loading a new one. Also, make sure that the parameter list you are loading is compatible with your CNC machine model and version.


To delete the Fanuc OT 900 parameter list:




  • Make sure that the PWE switch on the back of the CNC machine is set to ON. This will allow you to delete the parameter memory.



  • Select Edit Mode on your CNC machine by pressing Edit Mode Select Switch EDIT/MDI/AUTO/REF/H.



  • Press and hold the RESET and DELETE keys simultaneously while turning on the CNC machine. You will see a message saying PWE ALARM on the screen. This means that all parameters and programs have been deleted from the memory.



  • To confirm the deletion, press PWR OFF. This will turn off the CNC machine and complete the deletion process.



  • To cancel the deletion without confirming it, press CAN. This will return you to the previous screen without deleting anything.



Note: Deleting the Fanuc OT 900 parameter list will erase all your settings and options, as well as all your programs and offsets. Make sure you have a backup of your parameter list and programs before deleting them. Also, make sure you know how to restore your parameter list and programs after deleting them.


Some Examples of Fanuc OT 900 Parameters




To give you an idea of what kind of parameters are available in the Fanuc OT 900 parameter list, here are some examples of common parameters that you may want to change or check for your CNC machine:


  • Parameter 940: This parameter controls some optional functions of the CNC machine, such as cycle time display, parts count display, clock display, program number display, etc. Each bit of this parameter corresponds to a different function, and you can turn them on or off by setting them to 1 or 0 respectively. For example, to turn on the cycle time display, you need to set bit 7 of this parameter to 1 (10000000).



  • Parameter 960: This parameter controls some communication settings of the CNC machine, such as baud rate, parity check, stop bit, etc. Each bit of this parameter corresponds to a different setting, and you can change them by setting them to 1 or 0 respectively. For example, to set the baud rate to 9600 bps, you need to set bits 0 and 1 of this parameter to 0 (00000000).



  • Parameter 972: This parameter controls some diagnostic functions of the CNC machine, such as alarm history display, alarm code display, alarm message display, etc. Each bit of this parameter corresponds to a different function, and you can turn them on or off by setting them to 1 or 0 respectively. For example, to turn on the alarm history display, you need to set bit 0 of this parameter to 1 (00000001).



  • Parameter 1000: This parameter controls some program settings of the CNC machine, such as program number range, program number format, program number search mode, etc. Each bit of this parameter corresponds to a different setting, and you can change them by setting them to 1 or 0 respectively. For example, to set the program number range from 0 to 9999, you need to set bits 0 and 1 of this parameter to 0 (00000000).



  • Parameter 1010: This parameter controls some offset settings of the CNC machine, such as tool offset number range, tool offset value format, tool offset value sign mode, etc. Each bit of this parameter corresponds to a different setting, and you can change them by setting them to 1 or 0 respectively. For example, to set the tool offset value format to four decimal places with sign (+/-), you need to set bits 4 and 5 of this parameter to 1 (00110000).



These are just some examples of Fanuc OT 900 parameters that you may encounter in your CNC machine.
