Below is a list of FANUC servo amplifier alarms and faults with a short description briefly describing the source of each error code. Some point to the source of the problem itself, others point to the problem and do not identify the failing/malfunctioning component.

DC voltage of the main circuit power supply is abnormally high.

Internal cooling circuit faulty

Overcurrent flowed into the input of the main circuit. Input supply voltage imbalance, IGBT defective. (PSM-15 to PSM-55)

The battery voltage of the absolute pulse coder is low. (warning)

The main circuit power module (IPM) has detected an overload, overcurrent, or control supply voltage decrease, overcurrent, or control supply voltage decrease. Internal cooling circuit failure, Overload, Input supply voltage imbalance, IPM failure, or control supply voltage decrease of the power module.

Position control system fault. Due to an NC or servo system fault in the reference position return, there is the possibility that reference position return could not be executed correctly. Try again from the manual reference position return.

Having a few issues with a FANUC robotic packer. It stopped operation and I cant seem to drive it home. I have the alarm SRVO-073 CMAL alarm (group:1 Axis:4) and cant clear it, so thinking this is stopping me from being able to manually home the arm. Any ideas what the issue could be, from reading a few posts on here I got the impression that it is most likely the encoder. I have checked the earthing arrangements of the cable shielding and segregated the power and signal cables as best I could encase of any interference. I cant even find any reference to axis 4 in any of the documents we have, so not sure which motor it is referring to.

Hi Thanks for the responses. The controller I have is an A05B-2301-C375 and I will go and check the model of machine as I didn't get a note. I checked the encoder cable and seems to be in good condition, I also removed the plug a few times incase it was a bad connection, which has brought up the DTERR alarm, which I gather I will have to do a calibration/reset?

I have managed to clear all the faults by doing a pulse reset, I just need to remaster and recalibrate. does anyone have. a procedure for doing this, never worked on this machine before so having to learn as I go.

A FANUC alarm code, also called a FANUC fault or error code, is how a CNC control indicates there is a problem. This error message could indicate issues with either the machine itself, be that electric or mechanical. The FANUC error code might also indicate an issue with the g-code program.

Use the list below to interpret what exactly the fault code is trying to communicate. If you require a replacement part, know that MRO Electric stocks thousands of FANUC CNC replacements.

Hi Running a series 180i-M , the machine halts with no error or alarm. ctrl+F2 or any other function key is impossible. The softkeys in fanuc software work with mouse. The problem resolve after some time but randomly. The rest of the computer functions work fine ( alt+tab, alt+F4, using other applications..)

any idea

I own a machine from Newwai

And after the operation, I discovered the following

When I am inside a program and finished it and I want to go to another program

I do not find that the entry button for another activated program must be filled with the machine in order to do that

And the button dedicated to the barbarism of the bar is an act of an act

I have a Miyano mill with an O-M fanuc controller. I get an overtravel in the +Z error. It appears that the error is when the tool change carousel does not stop in the correct position. There are 2 magnetic limit switches that both have to be illuminated to show the controller that the tool change carousel is in the correct place. Sometimes only one switch is illuminated due to the cam rotating past one of the switches. Why would the tool changer sometimes overtravel in its revolution? The machine will run fine for an hour or so and then the error happens. We put a metal object in front the sensor that is not turned on and then step rotate the tool change carousel. This brings it back into proper alignment and the machine will run.

Any ideas what I need to do?

Thanks in advance for any assistance you can provide.

I have a fanuc control SERIES O-TC TYP AO2B -OO98-B501

machine, Lathe and the machine belongs to the Jolly company

I have a problem that the batteries have expired, and when I opened the machine, it was found that the parameter was not present

When trying to download the parameter, the control panel to run the motors does not activate

I want a way to solve this problem

Overcutting will occur in cutter compensation C. Two or more blocks are consecutively specified in which functions such as the auxiliary function and dwell functions are performed without movement in the cutter compensation mode. Modify the program. Overcutting will occur in tool nose radius compensation. Modify the program. Overcutting will occur in tool nose radius compensation.

Modify the program.

Under your operations passes tab, check your wear offset. This is set to "In computer" by default, which means your tool compensation is calculated in the CAM software, hence requiring your tool radius / dia offset in your machine controller to be set at 0. But this shouldn't produce any G41/42 in your code.

my problem is that when i set it to wear in computer it cuts the pocket .040" too short, when i tried to put wear i set the max to what is recommended and i put in my machine as wear in the tool -.001 just as a start but as soon as i do that i get those errors.

I don't have a Fanuc simulator but I do have a Mitsubishi M70 simulator on my laptop and the code runs just fine. This (I feel) is a control issue. I would try disabling the horizontal and vertical radius lead ins and use a perpendicular linear lead-in to pick up the comp and increase the lead-in value to at least .100". See if that will help.

Can you tell me the year make and model of the machine you are trying to run this code on? Which specific Fanuc control is on this machine? Have you been successful before using wear comp on this control?

okay i think your control uses tool D + wear = total tool dia for the g41/42 commands. But with wear you can ONLY enter wear offset. so basically 0 +- wear... change operation wear to in control. that will give you larger lead ins. Or zero out the tool Dia in the control and only use wear if that works for your fanuc control.

im attaching the PDF part of my manual that has to do with the cutter comp. there's an issue and it has nothing to do with the wear if i call in the program g41 or g42 and the D in the machine is 0 it cancels the cutter comp automatically. the machine reads two lines ahead in the code and if it sees two cutter comps it triggers an alarm. take a look and let me know what you think. im going to call Fanuc on monday and see what they say.

WEAR already puts out a compensated tool path. What does this mean? It means HSM is creating a tool path that is already compensated, i.e. moved from the desired tool path out by the radius of the tool..

this means you CAN NOT have a tool radius in the control because then you are double compensating. Tool radius offset in control should be ZERO or the WEAR of the tool. And HSM is clever enough to tell you what a safe value would be, (from your picture it would be 0.0125" and as you can see your .250 is way larger.

now when i said you should use zero value, i don't mean D0, no it should be D03 as your program. but on your tool offset page offset 03 (d03) should be zero. Now if your control doesn't allow that, i don't know. then put in a small number like 0.001 and that should let you run your program.

If you DONT want to zero out all your offsets in the machine then I suggest you use compensation type "In Control" this way HSM will put out non compensated tool path and you need to program tool diameter and wear offsets at the control.

Im having troubles to receive programs into a FANUC 0i-T control. Im using a proven cable and CIMCO DNC-Max. When I send the file from the control to DNC it works fine, but the inverse is not true. As soon as the data gets to FANUC it generates the 071 Alarm error. I have talked with the guys at Cimco, and apparently theres nothing obviously wrong with my DNC-settings or my cable, so that probably the error is on the CNC side, like a parameter, for example.

You may also want to set parameter 19 bit 6 to a zero so that the cnc will stop receiving programs only when it sees the % at the end of the file. Then all you have to do is press 'receive' on the control. It will read whatever program #'s you have coded and will read all of the programs in the file (main, subs, macros, etc)
