How to fine tune a Siemens drive for a spindle motor?

Thanks to nulizhang! Your answers really helped me in configure the drives. Now I can set commands to the drive and received status info from the drive.

Highly appreciate the help info from the forum! Also thanks to the mediator who organized topics very well!

My next question is who know more on how to fine tune a Siemens drive for a spindle motor? Especially if I do not have enough information on motor and encoder. Here is the detail:

Drive P/N:   6SN1123-1AA00-0LA1 (p/n is verified)

Analog plug-in board P/N:   6SN1118-1NH01-0AA0(p/n is verified)

Spindle motor:1PH2095-6WF41   (p/n cannot be verified, because cannot be seen)

Motor encoder: 256 pulses/rev, sin/cos 1Vpp   (p/n cannot be verified, because cannot be seen. When sending encoder signals in TTL from the drive interface board to CNC, I got 1025 pulse per motor revolution.)

Split from Questions in using 6SN1118-0NH01-0AA1 analog interface cards.

I follow your (nulizhang) suggestion of optimization by using SimoComU. The spindle was runnable but it had speed variations when RPM was higher than 2500. Then I read the manual and adjusted the following parameters on the Siemens drive:

P1142 was 2500, changed to 3000;

P1135 was 267.8 changed to 224 for satisfying P1135*P1142/1500 + .. <= 450;

P1145 was 100, changed to 200 %->300%, ->400%  (stopped at 400% its maximum is 1000%).

Finally, the spindle and the entire Deckel Maho DMU80P CNC machining center with new MS-Tech CNC control works great. Its spindle orientation and automatic tool changer work well too! The customer in Michigan, USA, is running the DMU80P in making quality parts now.

Thanks to this forum, to moderator, and to many warm-hearted professionals like you, nulizhang. I got very well understanding on the Siemens drives now, and will be happy to help others.

You can use SW SIMOCOM U --there is a function --check
