sending info via PM.

I am merely asking for machine serial number to see if I have data backup for a machine close to that. Oh, and if i am a Fanuc employee or a "Fanuc police", screen name "fanuservicetech" is an...

You will need to refer to machine builder's(NOT Fanuc manual) electrical wiring diagram and see what else is tied to Emergency stop circuit. I have seen anything from lube pump overload to air...

Please post the Fanuc control model and serial number of the machine.

Need to send you some info via private message. says you are not able to receive private messages. Please make necessary changes and I will send you more info.

Are you referring to the spindle drive unit alarm AL-17? If so, AL-17 means problem with NVRAM(non-volatile memory) chip on the spindle board. Please contact fanuc america 18883268287 for a procedure...

Did you check the +/-15 V on the CNC power supply itself? (not on the servo units). There are check pin on the PSU. A lot easier to check if you remove the cover off the power supply.

TGLS stands for Tacho-generator(the feedback on the motor)loss alarm. "L" is for the first axis (usually x axis). Looks like you've got a dual axis drive (i.e. both motors are driven by one servo...

Here's what a typical Fanuc DC servo unit looks like.
Like "greenery fr" said, you should check if any red LEDs are on when you have this alarm BEFORE you reset it next time.

How do you usually reset this alarm? i.e. by just pressing "reset" key on the keyboard? by turning power off/on? What is the servo unit number A06B-60xx-Hxxx? servo motors are yellow cap or black cap?

seen this a few times. Problem is the CNC power supply (A16B-1211-0890), the black box mounted to the master board. Basically, the +/-15 volt DC is low on that power supply. +/-15V is used in the...

Although 900 series parameters are Fanuc option parameters, they are machine specific. You need to contact machine builder to get a generic list. You can also find this list on Fanuc data sheet...

What model Fanuc control does this machine have? Fanuc 16, 18, 21, 0 ?

A02B-0121-J946, PART PROGRAM STORAGE = 1280 M Meters and NOT MegaBytes.
1280 Meters is equivalent to 512KB. On this CPU board A16B-2200-0900, maximum avail. memory is 1MB or 2560 Meters. I think...

Sorry. More clarification again. Does that mean your machine breaker is tripping? The reason I am asking is the drive units (spindle, servos) have different source than the once for control. When you...

What model Fanuc control does this machine have? If it has Fanuc 16i/18i/21i, you may have problem with +24V DC power supply on the machine (provided by Daewoo/Doosan). If it is any other Fanuc...

What model Fanuc control does this machine have? 04PC? 6M? 16P? etc.

Yes. 30i is one of the most advance controllers in current Fanuc line up. I am sure macro option is available on this control but be sure to check with the machine builder to see if it is already...

Just want to clarify. Does the communication works one way but not the other? i.e. will read but not punch? How recently was this functioning? FYI. You will not be able to replace the RS232 related...

Your initial post says "(started the machine using Reset & delete buttons)". If this is true, you definitely lost the parameters on the machine. Powering on the control while holding "reset" &...

You should be able to use 11M parameters for 12M as long as they come from the same model machine.

Please try turning "dry run" ON and see if the machine operates in G01. If it does operate with dry run ON then you may have spindle feedback problem (spindle position coder belt loose or broken) etc.

What typr of Fanuc control does this machine have? Fanuc 6? 10/11? 0T etc?

It is highly unusual to have the same problem on both X and Z since there are two dedicated circuitary for each axis. Did you just purchased the machine used and trying to setup? Sounds to me like...

Please observe the LED status on main CPU when you turn on the braker on the machine. See if the LEDs on main CPU comes on as soon as you turn the braker on (this is not normal since they should only...

If the trouble is intermitted, it might be worth while swapping the servo pcb a20b-0009-0320 (where the TGLS alarm is showing) with adjcent drive unit (y axis?). You can swap the pcb only (as oppose...

Sounds like main CPU board might be bad since the memory card reader ultimately connects to main CPU board. Is this machine new to you? i.e. have you used any of these memory card functions on this...

NO. Holding "Reset" and "Delete" at power on will clear program memory on Fanuc 6 control. "0" and "Delete" at power on clears all memory including parameters on Fanuc 6 control.
i.e Power on with...
