Spindle drive problem Ikegai lathe

[Prnya]

Problem with the spindle,not work nicely. I took out the fanuc ac motor and took off his belt,I took off the lid and clean the sensor re-adjust gap. Clean made everything and tried the motor without belt .The motor responds to the speed, But in the low rpm no power.I have to mention that this machine still stands on high gear,and should.be at low gear.Maybe that's the problem...My other machine (sister) changes depending on the set speed,while on this still stands on high gear.The button low high gear will not react (in other machine work).which is the principle of shifting?Does anyone know what could be? Why leaps alarm because there is no force in the beginnin. I think this is a problem.When I returned belt eject alarm in spindle drive unit #2 speed devation

What are load meter readings during no load rotation? Hope you have got this gauge on the panel.

I suspect one of transistors doesn't get opened, because of this motor can't develop the torque and reach the commanded speed. The slip of induction motor is his load.

I not have meter readings. Is there a possibility change that trasistors?How much would cost? Spindle servo unit A06B-6044-H007 motor type A06B 1003 B902.How it looks that transistor?
Do you know why I can not enter data on data table #1, I should enter the three items but can not
I brought all the rest and doing well, here we allow only numbers to value 200 but I have to enter 8191,5000,300
I have this same machine (sister)and everything on it as I entered these items.Last time when I throw a parameter I could enter this.
But we then missed address for function M4 (spindle counterclockwise).Always something missing or problem...
Always something strange is going on and do not know what, when the devil entered her.
second machine works perfectly. Now we are properly, except spindles and these three items that I could not enter, and still stands on high gear,

It is fanuc 10T, tnx for manual. I have ikegai PMC (keep relay, data table ,timer), I'm sure I typed everything well, But now does not allow me to enter 8191,5000,300. I know that number 5000 is the max rpm.Maybe because not due to the failure on spindle unit.Maybe this is why the in high gear, because with him managed spindle unit.My second machine itself operates that shift gear.No function for this (m41,m42,m38,m39).Thank you for your answers guhl

take a photo of the screen like on picture 5.5.4 (a) in the PDF
do you have ladder printout?

[Prnya]

Check this FANUC SERIES 10 PMC.pdf - DocDroid
Should you can see, this is original PMC data for my machine
I put on the internet

This is the machine that works. All the same, but I can not type 8191,5000,300. I can only value to the number 200. 200 is maximum. Now I am sick, I have to go to the workshop take pictures...When I better...
I've had this problem with PMC..
Before I had a different problem, see if you have the time Problem with spindle speed on cnc lathe machine

sorry for silly question, but have you set PWE into 1?

[Prnya]

Course! This is the main, could not change anything.

So you are not able to enter content of each table after inputting data on data table control screen (fig. 5.5.4(a)?

I not able only parameters on data table #1 see picture ,adreses (8191, 5000, 300) I not input this numbers, I input only number 0-200 in this data table, i not know why.... Before I can, but i not have adress for function M4, but now I have adress for M4 but i not inputing adress parameters in data table #1 8191, 5000, 300

Put the machine in emergency stop state first then try entering your data.

I do this.
Do you underesting... I entered 200 (example) but I no enter 8191 because can not. Machine not allow 8191, only 1-200 numbers

[guhl]

Have you entered correct data table parameters 00000010?
bit #1 = 1 means that your data length is 2 byte, which max readning is 65535
bit #1 = 0 means that your data length is 1 byte = 255, which max readning is 255

[Prnya]

I must check this.Today can not... Tomorow going to guarage to check. Maybe I mistake and entered 00000001.Tnx for you help

[guhl]

what about your spindle drive?
