hello friends i Need Help.. We lost parameters of our NC lathe machine during change of keypad.. we dont have any datasheets, backup parameters. We lost all them during our country hit by typhoon (Phillipines) Any help we really appreciated!
Model: Nakamura Tome TMC15M Lathe Serial: R12705 yr 1989
Control: Fanuc OT-a
Software ver: 669-07
Servo ver: 9046-B
PMC: M028-01 (everytime i enabled parameter 905 the machine RED led alarm light on, im not sure how many steps its ladder or its version "M or L"..)
SERVO MOTORS: X A3/3000 A06B-0123-B075, Z A6/2000 A06B-0127-B075
SPINDLE MOTOR: AC3 5,5 4500rpm A06B-0843-B902 w/ separate position coder (im not sure if this is serial spindle)
I try to put basic parameters from 900-910 and load some 300-700's parameters according to the parameter manual that mr. al_the_man, we eliminate all errors/alarm but the machine stay on boot screen "not ready" and machine LED alarm turn on. please help us we know that this machine almost 22years but with your expert help this machine will pump again and cut some metal works...
Step 1: Set up your Personal Computer (PC) or laptop to receive data. (click here for information on RS232 setup)
Step 2: Punch out NC Parameters as follow
Select EDIT mode.
Select PARAMETER screen (by pressing PARAM/DGNOS key once).
Press and hold EOB key while pressing
OUTPUT START.
* Note: OUTPUT will flash in the lower right-hand corner and NC parameters will be
output.
Step 3: Punch out PMC Parameters as follow
Select EDIT mode.
Select DIAGNOSTICS screen (by pressing PARAM/DGNOS key twice).
Press OUTPUT START.
Step 4: Punch out all NC Programs as follow
Make sure parameter no. 10 bit#4 = 0 (unprotect programs 9000 ~ 9999)
Select EDIT mode.
Select PROGRAM Memory screen.
Key in “O-9999”.
Press OUTPUT START.
Step 5: Punch out Offsets as follow
Select EDIT mode.
Select OFFSET screen.
Press OUTPUT START.
Step 6: Punch out Macro Variables as follow
*Note: Depending on the CNC software version, macro common variables (#500 to #999) can be output. However,
common variables #100 to #199 cannot be output. It is best to write them down, rather than outputting them.
Select EDIT mode.
Select Macro Variable screen.
Press OUTPUT STFanuc Series 0 Memory Restore ProcedureART. (variables will be output in program format.)
Step 1: If control is generating System Errors such as "Alarm 910 Ram Parity" or "Alarm 911 Ram Parity", control
memory must be first initialized. Parity Alarm is
usually caused by low memory backup battery. (click here to view more information on memory backup battery
replacement procedure)
Step 2: Initialized/clear memory by press and holding "RESET" & "DELETE" keys simultaneously while powering ON
the control.
Step 3: Control should power up to Alarm screen and it should show several alarms including
Alarm 100: Parameter Write enabled (PWE)
417: X Axis Digital Parameters
427: Y Axis (for milling machines) Z Axis (for lathes) etc.
Step 4: Push in E-Stop (Emergency Stop) button. Press "PARAM/DGNOS" key once to go to parameter screen.
Press "Page Down" key to go down to Parameter 38. Set parameter number 38 according to your backup
list.
Alarm 000 Power off alarm may generate causing the control to switch to alarm screen. Press
"PARAM/DGNOS" to return to paramter screen.
Page down to Parameter number 900 (you can also press "No." key then type in "900" then input to skip to
parameter number 900.
Set parameter 900 to approximately about parameter 932 according to the backup list. When certain
parameter 900 area data is set, control will generate a
warning message of something to the effect saying: press "Del" (Delete key) or "CAN" (cancel key) to
continue. Press "DELETE" key and continue setting
900 series parameters according to the list.
Step 5: Turn power OFF and then back one after about one minute. Control should come on and show alarm screen
still with several alarm previously mentioned.
If parameter backup is available on computer, setup the RS232 parameters on the control
Step 6: Input NC parameters as follow:
Select EDIT mode.
Select PARAMETER screen.
Press "INPUT" while holding "EOB" (End of block) key.
*Note: INPUT will flash in the lower right-hand corner and NC parameters will be input.
Alarm 000 Please turn power off message will appear once parameters are
loaded. Power OFF/ON.
Step 7: Input PMC Parameters as follow:
Select EDIT mode.
Select DGN screen.
Hold EOB and press INPUT.
Step 8: Input NC Programs as follow:
Select EDIT mode.
Select PROGRAM Memory screen.
Verify Program Protect Key is OFF.
Press INPUT.
Step 9: Input Offsets as follow:
Select EDIT mode.
Select PROGRAM Memory screen.
Verify Memory Protect Key is OFF.
Press INPUT.
Run this program to write data to OFFSET
screen.
Thank you for the reply.. but we dont have any back up parameters, even on soft or hard copy its all lost because of typhoon, when our office reach by flood and all was wash out... i wish someone have the same machine with working parameters.. i tried to call nakamura japan but they said that they dont have anymore data about this machine. they cant help us unless we apply for registration again of our machine but it cost about $2000 which is we cant afford to pay, so they can help us. but that machine was we already bought to another company that bought it from nakamura japan. so i think it should be free ?
