Speed control telegram details

good morning,

 I am working on siemens servo speed control operation. i have doubt about which telegram i need to choose for speed control with torque, speed, position feed back.

Use EPos in MDI mode.

Then you can change between Setup (like jog) and absolute Positioning on  the  fly

Hello,

For CU 391, For ALM = 999, For DO = 138 or 136 depends on drive application.

Hi,

I would recommend telegram 20 or 352 for the Servo DO - there are also ready to use SIMATIC FBs for those telegrams (LSINAExt lib):

But here you do not have a position feedback, I do not really understand why you need the position of the spindle? You just want to do speed control so a position is not relevant usually for that type of control.
