TAVOLA ROTONDA

The Ultra small intelligent G-WHI servo drive is perfectly tuned

for widest bandwidth and fastest response by overcoming the

non-linearity of themechanical load. This allow very fast, stable

operation, very high throughput, and error free operation.

. TheMaestro.

The whole orchestra of 60 servo drives is conducted by theMa-

estro, controlling and supervising the entire ‘bottling’ process.

The Maestro is a World- Class multi axis controller, precisely

executing the complex motion scenario. Harmonious Motion

is achieved by the Maestro operating in conjunction with the

Gold Servo Drives.

Solution highlights

60 Axes located on a rotating platform are used for high speed

bottle labeling and cupping. Bottles are automatically fed into

the machine and transferred to the rotating platform. The ro-

tating platform consists

of 60 high power, small

footprint Elmo DUETs,

an advanced integrated

Drive/Motor solution.

The Duets are essential

components in this ma-

chine due to the limi-

ted size of the rotating

platform. The Duets

are positioned on the

rotating platform, and use direct coupling to ensure high pre-

cision of rotation during Camera image capturing. Only High

power and a serial Ethercat cable is connected between the

Duets. The richness of the Easii tools and functionalities enable

tuning of the drives and optimization of their servo operation

to provide highest speeds, precision, and accuracy. The Easii

Advanced Servo Control incorporates capabilities to maximize

the optimization of the servo performance of any motor and

anymechanics. The Compact Motor/High Power Drive solution

is optimized for limited machine space. It uses high resolution

absolute feedback toachievehighprecisionandbest servocon-

trol and performance. The Duets solution must be rugged to

withstand the mechanical vibrations of the rotating platform.

The minimum cabling used in the solution results in minimum

influences of external noise, lowEMI andRFI, thereforeprovides

the best solution for large numbers of axes controlled by Ether-

cat serial communication networking.

Four high speed cameras are locatedat the stationary sectionof

the machine. When bottles pass through a camera, a snapshot

is taken and transferred to a host computer. The host computer

processes the picture data and calculates the exact label posi-

tion using an image processing algorithm. The bottle rotation

is controlled by theMaestro, Elmo’smulti axes controller, which

sets the initial target labeling position and waits for the Ecam

execute operation to start. The Ecam function running on the

Maestro is oneof the key functionalities used in theoperationof

this machine. Operating the Ecam using the Maestro has huge

advantages. All slaves operate in DS-402 standardized cyclic

synchronized position mode of operation. The Maestro and

Easii allow high interpolation levels for smooth motion trajec-

tories with a minimum number of Ecam points. It enable Fast

Dynamic table calculations, execution, table switching, multi-

hierarchy topology building, virtual axes synchronization and

many relatedadvanced features that simplify andaccelerate the

implementation process.

The advanced Easii, Elmo Application Studio Ecam tool combi-

ned with Elmo’s Embl

- Elmo’s Motion Block

Libraries, enable very

simple, fast design and

precise testing of the

Ecam trajectories to

raise the machine level

to operational within a

matter of days. By just adding several slave positions as a fun-

ction of the Master position and interpolating between the po-

sition inone of the advanced interpolationmethods. The Embls

are complementary to the Easii advanced tools setup. Elmo de-

veloped numerous Embls that simplify the development pro-

cess of the machine. For example Homing (all DS-402 methods

andmore), Output Compare (Pegs), Emulation, Ecam, PVT, Spli-

nes, Joystick….

Elmo continues to develop and introduce new Embls for the

users, without any request of payment.With the right tools Elmo

walks you through thewhole implementation process in a Sim-

ple, fast and intelligent manner, ensuring the shortest “time to

market” withminimumengineering resources.
