Hi Every one

 After replaced spindle bearing of machine due to alram no 25000(C4 axis hardware active encoder fault)Machine spindle is not running.

So here how canfixed this problem or identify the fault that external encoder faulty.

Can we run with out machine spindle with out c4 axis , which parameters are helpful

With best regards

Hi sir 

Thanks a lot for your good respose

Only on motor is used for spindle

I change 30200 2 to 1 but spindle is not move and alram 25000 removed 

I checked in axis service encoder and actual position is not same

Hi

you can see error

Here I tell that we check all cable shielding every ok 

Hi sir

Thanks  a lot 

I checked plc logic db3x.dbx1.5=1 and 1.6 = 0 I check phasicaly spindle motor no incoder installed only external encoder fitted.

Sir I changed 30200=2 to  1 and 3rd try with 0 after changing the parameter values then power off and on, the Alarm 25000 removed and machine get ready.no alram show.auto and mdi program run but spindle is no running.i try to changed db3x.dbx1.5 =1 to 0 and 1.6 but could not changed.

No spindle is not running in both parameter setting(1,0).before parameter changing spindle is runing in some degree and generat alram no 25000.

Sir what could be possible to rectify machine fault.can I run machine as turning with out external encoder or c4 axis.spindle motor specification pic is attached. 

Hi Sir

Bundle of thanks for your valuable response.i found external encoder is damage need to replace.i already order replace but her i have some problem. 

Dear Sir I checked motor Physically, don't found motor encoder and cable.

2nd i checked PLC signal DB31.Dbx1.5=1 and DB31.DBX1.6=0  i think its means no motor encoder , are I am Right, her what is the procedure that i can change DB3x.Dbx1.5=1 to 0 and DB3x.dbx1.6= already is 0. can i run spindle in turning mode without S4 :c axis:

when i change md30200=2 to1and 0 and 31040=0 in3try., in every setting alram disappare and machineis workin fine with out spindle move ment. before machine parameters  setting the spindle is move some degree in S4. But after parameter's changing spindle is in stop condition Programs Command in MDI and AUTO mode is excute But Phesically spindle is not runing. i dont undersatand what happen now what i do .

finally I revert all parameters in old condition but spindle is not move . if i move by hand after some degree machien stop due to alram 25000 

what i do sir please give me guidline for solution why is spindle is in stop mode.
