Simodrive 611U Master-Slave optimization?

 I am still busy, find little time to read your post.

Now please answer my question--

#1--What CNC system you use?

#2--Do you have all 611U system data back up --in other words--if I give your the old version servo motor , you will make your m/c running in minutes?

#3--Did you have master/slave issue when your old motor still good? or this issue coming to you when you use new version of servo motor?

Hello _oleksandr_,

I read your posts related to topic. Based on it, please reply to following points.

1. Is this oxy fuel profile or plasma profile cutting CNC machine?

2. How you define this as a master-slave configuration? Based on axes data or from machine manual? How the motors are connected? Is it possible that this could be Gantry application configuration?

3. How do you carry out optimisation of drives? Both connected to load? Optimising one drive on load? Disconnecting another drive? Please pay attention to this point.

4. Are you able to optimise single axis drive successfully, i.e. single drive + single motor?

5. Please provide the Siemens CNC controller MLFB number. Moreover how Hypertherm - MicroEdge pro card is interfaced to system. Is it controlling profile cutting process or axes motion?

HTH.

1. We have plasma profile cutting CNC machin.

2. Motors are connected as shown in the figure (Y-axis)

3. I did so optimization: Both connected to load, and speed controller optimization is only the master, optimization of the slave did not do, because it works in a mode - Positioning, I can not do optimization- Positioning;I think what I'm doing wrong optimization!

4. Are you able to optimise single axis drive successfully, i.e. single drive + single motor? I do not understand a question. I made successfully optimize speed loop from a master. 

5. Hypertherm - MicroEdge Is icontrolling profile cutting process and axes motion?

#1--What CNC system you use? 

we have CNC - hypertherm microedge cnc, which sends analog setpoint (speed) to Simodrive 611U;

#2--Do you have all 611U system data back up --in other words--if I give your the old version servo motor , you will make your m/c running in minutes?

I do not have the actual backup for Simodrive 611U, but now we are talking of the motors master/slave - this original motors - 1FK7042-5AF71-1TA0;

Sorry , it may be my mis-understanding.

"but now we are talking of the motors master/slave - this original motors - 1FK7042-5AF71-1TA0;"

I need make it clean--You have CNC m/c using Non-Siemens CNC system.

3 axis drives all using 611U, --you 1st post for issue of a single axis drive controlled motor defective--old version--5AF71-1TA0, but you fix it by replacement of new version motor --2AF71-1TA0.

Now you have issue for master/slave optimization for the double axis drive, they all use old version motor--original from m/c builder, (Y and Y1)?

 make sure this time it good understand your problem.

if yes, can you let me know the story the master/slave issue is happen for how long, it is happened before or after the single axis motor defective and replaced?

At the same time--I need to know who made that setting for master/slave.

and if you made it --did you followed Siemens manual for every step?

I remind myself for a  key point--master drive is speed control loop and getting speed setpoint. but slave drive will be current control loop getting current setpoint , I did not check all your post and some of your pictures being blocked, I just remind here for you.

 motors master/slave - original, we had a problem with the X-axis (we changed the motor on non-original). Master receives from CNC setpoint - speed, and sends the setpoint (position) on the slave.I have the last backup for 611U slave, - it works in the positioning mode (X462/X461).

How do I optimize operation master/slave.

 You didn't like to answer my question, only ask question in your way. I want to know the story--master/slave issue--who made that project-- all parameter setting? original machine builder ? or some one else ?

If the key point is wrong your will never make it in best working condition. here is picture I cutting from 611U book, you can find this in Siemens 611U manual then continue  to  read and test .

My idea is slave drive should be in current control--NOT in position control!  

then the whole 611U drive master/slave together doing the task of speed control. CNC sends position setpoint to master, 611U drive (the whole drive-master/slave) +CNC doing the task of positioning control, in the way we call 611U drive system doing the job of master/slave.

maybe in your m/c--it was other design, it is possible using the function --in Siemens CNC , we call it Gantry function. your  611U drive Y and Y1 all in positioning control. Y is leading axis, Y1 is following axis, --IT IS gantry function--NOT master/slave function. you should discuss in another direction--"Synchronization Y/Y1 axis in Gantry function"--and best post question in "SINUMERIK CNC system branch"

I did not read your whole post --so many information, if you already did like in Siemens book suggested, let me know, post result.

Hello _oleksandr_,

I studied your machine & my observations/suggestions are as below.

1. Your axes master & slave configuration/coupling is dependent on selection of drives DI logic. So you need to study Hypertherm Micro edge pro PLC logic. This helps you to understand the machine operation logic.

2. Y & Y1 axes master slave configuration information is must. From application point of view, Y i.e. master is positioning axis & slave is speed synchronous axis. Needs to confirm from OEM.

3. Simucom U is basic tool which is for commissioning of drive. You need to set factory default parameters. Independently set Y & Y1 axis parameters & carry out optimisation. Put both the axes in operation i.e. connect to machine, modify parameters as per application i.e. as per master & slave configuration & depending upon logic drive I/O & machine should run as per the commands from CNC controller.

HTH.
