Thanks for your responses. it is a big help to get my drive sorted!

Hi I'm trying to fault find a drive and need to mimic the signals on CN2. I have a spare position/speed sensor but can't find the details for the temperature sensor.
can I use a resistor and if so...

the machine was working well until I got the AL-12 high current alarm on the spindle. Blown igbt/transistor module on the lower board. it was then sent in for repair. Now an al-20 which is...

further testing and the problem is intermittent so I don't think it is the phase supply. One of the remedies for AL20 is to check the control boards connections and a clean has the drive booting...

"Yes, make sure phases are correct connection in clockwise rotation. Also any other position where the 3 incoming phases are used. I had a drive where incoming phases were correct but crossed...

The drive was just repaired and they claimed to have check the transistors.

Do you mean the transistors on the drive board or the transistors/igbt modules underneath?

Does anyone have any experience with Fanuc drive errors? I was getting a high current alarm Al-12 and sent the drive in for repair, now the drive is giving AL20 high current on one phase - checked on...

Thanks for the input. You can change the compensation to whatever you like but it is an option parameter.

I discovered a little more today.

I found my machine is using the D in the code and...

my old 0m-A system only has H offsets. I think it is set for cutter compensation C. I have been reposting to hit tolerance but I'm trying to use the "wear" compensation feature in fusion360.

my...

I thought I'd chime in and post the solution for others that may have the same problem.
the board wasn't dead. I found another post on these formums with a reference to a 2V floating analogue...

thanks for the input. I wasn't sure if you were refering to the main control board or the spindle amps board.

I swapped over the rom chips when replacing the main controls board. this included the...

I did some measurements and while the spindle changes the sign of the commanded voltage so m03 and m04 work reversing the spindle the voltage on VCMD is pegged at 2V which is what the amp rpm is...

the board is a A06b-1010-0240 the amp is a 6059-H03. I should be able to find that on the amps input to test.

Can anyone shed some light on why the spindle speed s command has no impact on the spindle amps speed?

I can command any speed and have tried values from S200 to s5000 and the spindle amp says it...

I solved it by jogging past the dog and inputting the value into the zero sep parameter and changing p22 to set for the y axis.

I'm trying to set my zero return on my old mill and the X and Z will zero return and set the parameters but the Y wont.

the Y parameters are not set yet and are zero in the parameters. the axis...

I'm investigating the possibility of replacing an old Fanuc drive 6055 with a VFD.

I need to get one that will interface with the old okuma control. luckily it is a lathe with no orentate. The...

I was quite careful when doing the soldering but I wasn't as concerned with heat input as I was on the spindle amp since I wasn't trying to reuse and salvage components.

The chips were surrounded...

I have found the keys are responding. diagnostic parameters in the 20's form set patterns when the keys are pressed.

I have tried reseating all the plugs but it hasn't helped.

one thing i have noticed is that the leds in the keys don't flash on as it boots like normal.

there may be some life in it since it...

would a bad ladder chip throw an error? since it is 0m-a you cant view the ladder.

I have loaded the parameters by hand.

I think I made it worse.

I had a go at replacing the chips. I pulled the main board took out the chips and replaced them with sockets. it all looked ok.

After reinstalling the board i got the...

could you give me some more info on how you fixed the servo driver?
I have a 6055 drive that has good wave forms on the drive board but is still giving AL-12 and the motor is ok like yours.

yes replacing the right chip and it all goes well. get it wrong and it could be a real mess. that’s why the 2nd port is an attractive option.

I'm guessing it is the RXD side since my machine can...

thanks memoryman.

Do you know if the 2nd port is capable of rs232 or is it used for something else?

Was it an option or is there some trick to get it working?

I'll give 914.4 a go but for some reason i'm not confident it is correct for the 0m-a.

I'll find the wiring list for you.

you should have a 25pin rs232 on the side of the control cabinet.

thats what i'm guessing and hoping someone might know which one.

it may be 914.4 from the list I have but someone in the know told me the list wasn't 100% correct.

My 0-ma has a honda connector on the main board that is labled R/P 2 (reader punch interface) and I would like to see if I can get it working.

My port 1 can only send data and can't recive data...

hi regina I tried responding to your pm but it said you can't recive pm's or have it turned off?
