Simodrive 611U Master-Slave optimization?

Simodrive 611U Master-Slave optimization?

We have a system of master/slave:

Setpoint (speed) on the Master comes from the CNC 0..10V,

Master(mode-Speed/torque setpoint):

Simodrive 611U- 6SN1123-1AB00-OHA1 + 6SN1118-0NK01-0AA1 – motor – 1FK7042-5AF71-1TA0;

the master sends the setpoint (position) on the slave via X462

Slave(mode – Positioning mode)

Simodrive 611U - 6SN1123-1AA00-OHA1 + 6SN1118-1NJ01-0AA1  – motor – 1FK7042-5AF71-1TA0;

All works, but there is a slight vibration when moving (only one side)

I think that the motor are not in sync.

How do I set up a master / slave:

Master P890=1; P891=-1;P892=1;

Slave - P890=2; P891=0;P892=0;

How can I optimize the master / slave operation?

For example, the setting of the speed controller:

Speed controller P gain = 0.14

Speed controller reset time = 5.37

For the master and the slave must be the same?

On the Slave is now set Kv factor (position loop gain) = 3 if you need to change it?

In annex has a configuration file of the master and the slave, electrical connections, etc.

The video shows how the motors operate.

 I see you post, but what is wrong for followed 2 posts blocked by Siemens system.

I am very busy now , will find time to discuss with you and other members

But I checked your loading pictures. it is the 1st time I see your m/c configuration. it is non-Siemens CNC system, right?

so I have 2 suggestion now--

#1--you should make speed loop optimization 1st--master/slave function belong to speed control loop

#2--do you know, if we use Siemens CNC, in this m/c configuration, I will use Gantry function

Y1 will be Leading axis--Y2 will be following axis. that will no issue for master/salve--but you have no choice for your system

What do you advise?

I didspeed loop optimization for master (Y1),

Speed controller P gain = 0.13

Speed controller reset time = 5.37

But the motion we have the difference between the setpoint and the real speed.

Perhaps P gain = 0.14 is too small? It should be increased to 1-2?

Slave -Positioning mode, I can not do Execute automatic speed controller setting... -> error Speed controller enable missing, function canceled.

why can not I doExecute automatic speed controller setting?

I set the same parametersP gain = 0.13/ reset time = 5.37 as on master.

what I can try another???

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?
