What I like to do is control them from a PC without using the 810 NC. Does any one have the pinout details for the x141 drive bus connector and the communication protcol.

the control card is 6SN1118-0DG21-0AA1 installed into a 6SN1123-1AA00-0BA0

                                                                                                                                                                                                                                                    

 Not possible.

Simodrive D are controlled via Drive bus + Equipment bus by 8X0D controller. Moreover drive software is downloaded from Sinumerik controller during intialization (power ON or reset) as such not possible to run 611D drives without CNC controller.

 Technically it possible to run SIMODRIVE 611D w/o SINUMERIK 840D, --and I really saw the  machine made in USA working like that, and I  really have the drive bus pin out. 

But actually I cannot give you that file--

1st-- It is Siemens internal Factory and D&R use only--it not very useful for , even for services, such as for myself--more than 20 years 840D+611D services and project, I never used that pin out. (PS: for Device buswhic is useful for repair shop and trouble shooting--I posted in this forum--check in SIMODRIVE branch)

2nd--The the m/c builder I mentioned in USA , who had OEM agreement with Siemens --so they got prototypical of 611D --drive bus--in condition they purchased a large amount of Siemens 611D production. Let me say something --that m/c they made is not so good--compare with Siemens original system, I mean 840D controling 611D--their system was lack of system information for troubleshooting, error messages and so on, it was very hard for maintenance and service person.

3rd, 611D was discontinued for years by Siemens, it not worth to invest time and money to it.

just keep remaining systems in the world running , spare parts for another 20 years.

If you really want to do some project, I suggest, use SIMODRIVE power section your have then purchase some 2nd hand 611U control card to make system

and you can sell your 611D card to get funding for your 611U
