The Beta drive’s parameters are NOT part of the CNC Parameters and MUST be backed up separately.
To get to the punch/read screen for the Beta drive:
Go into SYSTEM, press the > key till you see PMM this is where the Beta parameters are stored. Press the PMM soft key, press system soft key then param soft key. Select which group you want to save, then press oprt key then F12 until you see the punch & read soft keys.
To Backup the Beta parameters:
NOTE: To save (READ) Beta parameters you must first rename or remove the existing programs #9110 and #9120 from the part programs if they already exist. (Or you can set parameter 3201 bit 2 to a 1), this will allow you to over write the existing part programs.
When you do a READ in the Beta parameters, the controller creates a part program in the #9000 area. This is established by CNC parameter #8760. Set this value to 9100. The Fanuc controller will add 10 for group 1 making the output program #9110 and the controller will add 20 for group 2 this making the output program #9120)
To Restore the Beta parameters:
Go into system, press the F12 key till you see PMM this is where the Beta parameters are stored. Press the PMM soft key, press system soft key then param soft key. Select which group you want to restore to then press, oprt key then F12 until you see the punch & read soft keys.
NOTE: To load (PUNCH) Beta parameters you must have program #9110 for group 1 (A-Axis) and #9120 for group 2 (B-axis) in the part program area. Be sure that these part programs actually contain the parameters for the Beta drives.
