Hello,

I Have old traversing platform /moves small railway carriage/....I need to repass it....

There are two AC motors /both sides of platform/ and I need share load between them....

...It is possible to share load with 22kW /and maybe more/ AC motors....Is it possible to simply use one

Inverter/say G120/ for both motors?....(it worked for me but with two 1kW motors before)..

Thanks a lot....J

Thanks a lot.....

It is nice example....But it use 2 inverters....and telegram 352....

And what I want is to use position functions of invertor/invertors/epos or TO and load sharing at the

same time...in this way I can not use telegram 352....

So is there any tested Solution for this configuration?/I have S7-1200/

Thanks J

Hi, I think You need to clarify your requirements. Your application has changed significantly from one post to the next.

In the first post regarding load sharing You ask if it's possible to use just one motor ... well, Yes, but then there is no load sharing requirement and you then need to consider a mechanical linkage between both sides.

To me it sounds like you are describing a roll carrying car in a steel mill or similar.

How/why do you want position control and load sharing together, should the drive mechanism not remain as a vector function and a separate method employed for position i.e. barcodes or a laser distance sensor.

Or is your intention to use one drive/motor as a position master and have a slave to assist, or if your application is more refined, are you thinking about synchronism?

A photo of the patient would assist greatly.

Hello...Thanks...

I wrote 

."Is it possible to simply use one

and

"I woud like to use Epos ot TO/technology object/"

To put it together I want to Share load between two motors and at the same time to use Epos or TO

functionality....position based on encoder/absolute if possible/ on one of two motors....

Just now I have no picture but it is simmilar to two Rail mounted Gantry Crane with automatic positioning...

Thanks a lot J.

Thank for this answer....

We will probably use two inverters,two 22kW motors,rigid mech.coupling between gearboxes....

In this case/and 22kW motor/ is it enough to use first motor in position mode and second in speed mpde with Droop activated in both inverters??        OR

to use first motor in position mode and as a torque "master" using analog output for second motor which will be it in torque mode??

Thanks a lot J...
