Difference between SIMOTION & SINUMERIK AUTOMATION system

Hello Experts,

In this forum, I learnt about SIMOTION as - With SIMOTION D, the SIMOTION PLC and motion control functionalities as well as the SINAMICS S120 drive software run on shared control hardware. 

In Sinumerik CNC automation it is - CNC controller with PLC & drives controls the motion. 

So I would like to know what is the difference between these two technologies.

Thanks in advance.

Regards,

SIMOTION exists in the world between PLC and CNC, the motion controller.

Motion controllers have preset commands to make simple position changes, commands like MOVE, POSITION, etc.  There is an interpolator that automatically calculates a reference profile to accomplish this.  With a PLC, you would need to write your own interpolator (in general).

CNC's are designed for complicated motion profiles and are made to do them simply.  Their commands are more like Make A Circle of Radius X and Center at X,Y.  Its internal interpolator would figure out which axis to use, how to synchronize them and how to generate the references.  They also include commands for tool selection, tool offsets and other specialty functions specifically for machining.

There is some overlap between all of these units (many PLC's have some basic motion control commands, SIMOTION can do some basic CNC, CNC can do PLC).

Hello

To add to Jeff's post ...

SIMOTION Applications can actually sometime be more complex than SINUMERIK and to say that SIMOTION is used for simple applications is an understatement.

Like Jeff has observed, there are areas of overlap between PLCs, Motion controllers and CNCs.

Motion controllers is a newer concept as compared to other two. Earlier Motion control was usually done by inserting a specialised Positioning Control module in a PLC Rack.  

SIMOTION is basically a combination of a PLC Controller + Motion Controller. It can execute the basic logic of PLC besides being a Specialised Motion Controller. It can be configured using standard Drives , HMIs and I/Os. Can start with just 1 Axis and go on to multiple axes.

SIMOTION is used more where ( Sometimes Complex ) but repetitive controls are desires.
Examples are : Printing Machines , Packaging Machines,  Rotary Cutters , Flying saw etc.
Normally only parameters like length , speed etc are adjustable.

SIMUMERIK is used in typical CNC machines. It comes with its own Display with motion controller.
Usually there machines are used for making variety of products by changing the Machining programs. Generally will have Minimum 2 Axes or 3-Axes.

Here is an interesting Presentation of comparison between SIMOTION and SINUMERIK .

Hope this helps

 Witch on is more advance ?SIMOTION OR SINUMERIK?

SINUMARIC is not with fixed programm and Display with different model no?

 This is like comparing Apples and Oranges ... both are highly advanced in their respective applications.
