hello,

im working with this machine and i need to increase max speed from 20000 rpm to 30000.

the manual says that i must change MD 36200 to 30000. there is something else to change apart of this parameter?

thanks

i have been editing MA's but spindle stil running in 20000 rpm. parameters i've changed:

MA 32000=30000

MA 35100=30000

MA35130=30000

MA35160=30000

MA 36200=30000

MA 32010=30000

MA 32020=30000

MA325110=30000

 Are you talking for max speed for Axis such as X, Y. or you want speed up spindle?

before I get your answer--I guess you want speed up spindle--tips--you need check menu "Parameter--Spindle Parameter--Spindle limitation, there are setting data min. speed and max speed.--I think that is still in 20000 RPM

hello and thanks for your answer!

i've checked the spindle limitation and is in 30000... someone any idea?

You not answer what axis speed you want to change--spindle speed?

sorry, yes i want to change spindle speed

 I checked 840D PL manual (I think 840D sl for SP data is not change). Buy I think you already modified all MD you need, , can you please check MD35110, and check " Setting data"-- spindle speed limitation --take picture of that page to show me--in case you setting in some place else

sorry, yes i want to change spindle speed

Which is spindle motor? 

How is it controlled?

Please provide complete motor name plate & drive details.

OK i have a picture of the screen (i guess is what you are asking for), as i said, all parameters that i know i have changed to 30000. MD 35110 is 30000

the spindle (not a siemens motor) is 24000 rpm max and is controlled in sinamics s120 using servo mode.

No, I do not want the HMI screen. I want the name plate details of spindle motor. 

Anyway, could you please attach your machine's NC back up data here?

Hi again,

sorry but i'm not allowed to share this info so i will have to continue by my own. In any case, thank you for helping me

 I see your S1 setting is OK--do you have ability to test that 3rd party motor by SINAMICS --NOT by 840D, by STARTER--to see it can run in 30000 rpm

hello,

yes, only using starter im able to run spindles to 30000 rpm, in that way there is no problem.

 Hi, remote help is always hard. Let's try other way.

#1--Can you try to make your S2 running 30000. or any speed you like.

#2--Can you try to change NC MD to make your S1 running speed lower than 20000, such as 18000

#3--Can you check the S1 configuration--that means--there is gear or No, feedback using motor encoder or another direct encoder---for this info. you can get from OEM electrical drawing or Check NCMD 30200 =1 or 2

PS: how many years of your m/c? can still get support from m/c builder, call them to get help

Hi Dear

that is spindle
