SIMOTION PRINTstandard What is it, what does it provide?

PRINTstandard uses the system functions of SIMOTION in a standardized way. Print Standard provides:

+ Open source function library and programs for any axis in printing presses + Strategies for all applications in printing industry + Uniform axis mode manager for all type of axis + Centralized interface for all motion control commands to the axis + Easy group building for several axis +  Interface to automation system or program +  Interface to process controls like register control or tension control

What does SIMOTION Print Standard not provide? − No machine automation − No fault reaction on drive faults − No startup sequence

SIMOTION PRINTstandard SIMOTION System Software – Task System


SIMOTION PRINTstandard SIMOTION System Software – Task System

: Cyclic interface to the MotionTasks and machine control for all axis

: Each axis is assigned to one MotionTask 4 axes in PRINTpositioning

: Servo, IPO, and IPO2 for position control and motion control functions and each has a user synchronous task.

:

: E.g. fault tasks


SIMOTION PRINTstandard What Attributes has the Software?

PRINTstandard attributes: + Axis mode manager is the same for virtual and real axis +  It can be extended by a user specific program without changing the standard + Virtual axis with Cam/Gear-functionality + Drive-, Pos- and Cam/Gear-axis use the same mode manager and interface + Cam/Gear-axis can synchronize to multiple masters + Any axis can be master (setpoint chain or actual value coupling) + Each axis use three different program parts executed in different tasks

1 Motion Task, 1 Background Task, 1 IPO Synchronous Task Attention in centralized concepts – the number of Motion Tasks is limited to 32!

+ All drives have servo control functionality: Even winder axis can be operated in servo mode

+ Technological controls interface to the synchronism between master and slave by a Tech-Task and addition or formula technology objects


SIMOTION PRINTstandard How does it help automate your Press?

The variety of printing presses and converting machines require different motion control and automation solutions. The construction of the press as well as the cabinet building determine the HW and SW concepts of the specific solution. The Software PRINTstandard provides functions, operating modes and methods which are common in printing industry and specific structures and set point chains which differ in each printing technology. The machine specific solution is built out of tested software modules. Parameterization instead of programming lead to a „time-to-market“ advantage:   Axis mode manager   Printing press specific set point chain, methods and technological controls

Both elements are part of the PRINTstandard, application examples are provided. The open software makes it possible to implement OEM specific know how:   Press automation standards like OMAC can interface to PRINTstandard   Scripting mechanisms makes engineering more reliable and repeatable

All different applications are compatible and can be used in the same project.


SIMOTION PRINTstandard Printing Press Automation – Software Structure


SIMOTION PRINTstandard Printing Press Automation – Set Point Chain Principles

  GM: Global Master (virtual) for machine or production operation. The GM provides positioning functionality and velocity set point

  LM: Local Master (virtual) for group operation, format adaptation and distributed synchronism. The LM provides gear, cam and positioning functionality and velocity set point -  Distributed synchronism for modular automation. -  Group operation for multi drive print units or folder section. -  Format adaptation for format variable presses.

  Add: Addition object of “additional technology objects” for continuous influence of process controls

  Ctrl.Task: Process controls like winder, tension or register control   RA: Real Axis for local axis oriented operation. The RA provides

gear, cam and positioning functionality and velocity set point. It can be the master (set point or actual value coupled) of other axes for simple set point chains and has a position controller referenced to technological units (load side)

  DO: Drive Object of the SINAMICS with current controller, speed controller and DSC, the dynamic position controller with encoder resolution


SIMOTION PRINTstandard Printing Press Automation – Distributed Synchronism

For the distributed synchronism the set point has to be send via the distribution network used for clock synchronisation:   The global master (GM) provides in machine operation the speed or positioning set-point

for all clutched drive groups (machine modules) or single drives   To avoid communication overhead in distributed systems, each decentralized controller

has a synchronized virtual axis (local master – LM) as an image of the GM   If you need more than one production reference (GM) in your machine automation

structure you will need one LM in each controller per GM   This type of LM does not need an operation and the software automatically synchronizes

to the respective GM by a software configuration switch

SIMOTION PRINTstandard Printing Press Automation – Group Operation Scheme

For Group operation PRINTstandard provides two different possibilities:   Virtual axis (LM), which synchronizes to the GM

or runs in local mode, while several real axes are clutched to it. The virtual master is operated as if it was a single motor, while in reality several motors are synchronized to this LM. This is useful, when the real axes do not need operation but only synchronization between each other. For each group of drives a LM is needed.

  Real axis (RA, unit master), which clutches to a virtual master (LM) or runs in local mode, while it is the master for several other real axis. In this case only real axis need operation while the LM does not need operation or even does not exist.

SIMOTION PRINTstandard Printing Press Automation – Group Operation Scheme

Basic operation modes:

  Local speed (GM, LM, RA)   Positioning (GM, LM, RA)   Gear (LM, RA)   Cam (LM,RA)

Both group operation possibilities:   The LM is the reference for all Real Axis in

“global gear mode”. The LM can run in the shown operating modes while all RA follow

  The RA Unit Master is the reference for the other RA in “group gear mode”. The RA Unit Master can run in the shown operating modes even in “global gear mode” to the LM, while the rest of the RA follow. The group gear mode can be set point or actual value coupled. -  Set point: less calculation power needed -  Actual value: when the master has

relevant following error but the slave must not


SIMOTION PRINTstandard Printing Press Automation – Format Adaptation

Set point chain for format variable presses including distributed synchronism:

  Nesting depth of 4 objects to synchronize the form cylinder to the machine reference

  GM: Virtual master calculating the machine set point as speed or positioning reference which is web based and normalized to 1m circumference (1m = 360° length based)

  1 / F: Gear of the LM “following object” to convert the web based set point into an angle based set point (format based)

  LM (Machine Format): Virtual master only used for the format reference and follows the GM

  LM (Format): Distributed local master, synchronizes to format based LM with possibility for group mode operation

  RA (Form): Real axis format based   LM (Web based): Distributed local master, synchronizes to web

based GM with possibility for group operation   RA (Transport): Real axis web based

SIMOTION PRINTstandard Printing Press Automation – Operating Modes

Operating Modes are selected through a defined number (or program variable) and has “active parameters”, which can be changed during operation and will be executed immediately by a motion command. The operating mode program is executed in a motion task. A operating mode change is checked in the background task and restarts the motion task resulting in a defined behavior time wise. The motion task is only finished in e-stop, all other modes do not. Therefore reload is only possible in e-stop.

The program checks the “active parameters” cyclically and executes the respective motion command if there is a change. In gear and cam mode the back-ground program checks if the master or cam is changed and restarts the motion task if it is so. The 5 different referencing modes are selectable by a No. and stop the axis after the movement if there was one (referencing on the fly is not implemented).
