Hello everybody
Can anybody tell me if Siemens has a comparable command like Heidenhain M126?
So to drive the shortest way in a path optimised manner.
E.g. circular table is at 359 degrees, aim 1 degree, 2 degrees direct way, instead of 358 degrees.
Thank you for your help!!!!
Regards from Karlsruhe

Hello Ani-Mat
I just assume now it a Siemens 8xxD.
You can use the following provided that you have a rotary axis. If your C axis is set up as a linear axis, then you always have to drive back.
C=DC(-value-) absolute units, approach position directly
C=ACP(-value-) absolute units, approach position in positive direction
C=ACN(-value -) absolute units, approach position in negative direction

Hello
Thank you! Yes, it’s a 840D controller, AXA machine.
I have end endlessly rotatable table. The values however are from 0-360 , so that is comes to troubles. At the moment is always goes the long way. I always have to enter the output like this:
C 356 A1..
C 359 A1...
C= DC(1) A1..
C 5 A1...
Should that look like that????

Hello
In general you can also add DC beforehand then the machine always chooses the shorter way.
So when that is desired just leave it out.
C= DC(356) A1..
C= DC(359) A1...
C= DC(1) A1..
C= DC(5) A1...
Regards

Get rid of the space between the C= and DC:
C=DC(356) A1..
C=DC(359) A1...
C=DC(1) A1..
C=DC(5) A1...
Otherwise you probably get the error c= not defined or something similar
