Dear Experts

I have sinumerik 840D Control. When i input command M2=19 and execute it moves spindle and stop at angle of 45 degree but i want to stop it at 90 degree. is there any possibility to change the spindle degree according to my requirements. i also want to know the complete description related to spindle orientation parameter and configuration. how sinumerik works when i enter M2=19 command. i also used SPOS=90( but no response from machine).. i want to understand sinumerik and plc programming for spindle orientation and how can i change it to my own requirements.. 

Your command "M2=19" is a spindle orientation command for spindle #2.

The spindle position for orientation by M19 is to be define in a SettingParameter 

• SD43240 $SA_M19_SPOS = <position value>. This is an axis specific parameter.

By programming via "SPOS" You can define the orientation position directly by definition of the spindle number in square brackets: 

• SPOS[2]=<position value>

Your test via "SPOS" (without spindle index in square brackets) is always related to the MasterSpindle.

Dear Sir

I read the answer and i did as you said. i go to

parameter ---->setting data

but there is no parameter number SD43240??

There is only 6 to 7 parameter visible.

how can i see that parameter?

i tried another SETUP--------> Machine Data------> General MD(10000--->19800)

                                                                                           Channel MD(20000---29000) 

                                                                                           Axis MD(30100---38010)

                                                                                            Driver MD(1000---4725)

                                                                                            Display MD(9000---9999)

Dear Sir

I find it in parameter---> Misc-----> Axis specific Data-->43240

value of 43240=0

i changed it to different angle but spindle always stop at same angle(22 degree), there is no change in spindle orientation with M19 command..

I used SPOS[2]= 90

then spindle change its angle at 90 degree. i can change spindle angle with SPOS[2]= 90

but M19 is not working like i want.. when i enter M2=19 spindle always orient at same angle..

what is the problem, why spindle stop at same angle.. 

Dear Sir

today i tried again and now this time i successfull.. i am little bit wrong.

paramter----> setting data----> Misc-----> Axis specfic data----> then upper left corner , ichanged Axis to SP2 then edit 43240= 136 and now M2=19 works and spindle stop at 136 degree...

Dear Experts

Problem solved.
