connected to a higher-level control is illustrated in Figure 1. Each <br />
of the AC Drives is equipped with a CU310 Control Unit. This unit <br />
contains the field bus interface for connecting to the higher-level <br />
control. CU310 DP with a PROFIBUS DP connection or CU310 PN <br />
with an integrated PROFINET interface can be selected. In both <br />
cases communication between the control and the drive takes <br />
place in accordance with the standardized PROFIdrive profile.<br />
CU310 offers functions ranging from the simple speed controller to full positioning functionality. Drive-related inputs/outputs <br />
can easily be linked in the CU by means of BICO technology. This <br />
permits the greatest possible options for drive and higher-level <br />
control. <br />
Drive-related inputs/outputs can be linked via the integrated I/O <br />
interface. An integrated TTL/HTL interface and a DRIVE-CLIQ interface are available as encoder interface. For a version with an <br />
integrated motor this encoder interface features the advantage <br />
of an electronic rating plate.<br />

“Safe brake control” (SBC) and “Safe stopping” (SS1).</div>Bloggerhttp://www.blogger.com/profile/02093150578229231253noreply@blogger.com0tag:blogger.com,1999:blog-7409540096668448495.post-29556209027241231702011-08-17T05:10:00.000-07:002012-11-05T06:38:12.730-08:00SINAMICS S120 AC Drive<div dir="ltr" style="text-align: left;" trbidi="on"> SINAMICS S120 AC Drives – a building block <br />
for integrated drive solutions<br />
SINAMICS S120 is a modular drive system with Servo and <br />
Vector Control and is the SINAMICS product most suitable for <br />
demanding drive applications. The stand-alone SINAMICS <br />
S120 AC Drives complement the DC/AC units, which use a <br />
common infeed and controller designed especially for <br />
multi-axis applications. Optimally tailored, integrated solutions can be designed for any type of application based on this <br />
building block system.<br />
The ready-to-connect SINAMICS single drive<br />
SINAMICS S120 AC Drives are designed for single-axis applications but can also be used for multi-axis applications. <br />
Positioning tasks can be reliably executed as well as synchronous movements and motion control tasks. In multi-axis <br />
applications with spatially distributed drives, distributed <br />
solutions based on SINAMICS S120 AC Drives offer a practical <br />
alternative to a central drives line-up.<br />
Universally implementable<br />
SINAMICS S120 AC Drives can easily be implemented in conjunction with higher-level automation systems using field bus <br />
interfaces and the standardized PROFIdrive profile. Solutions <br />
to standard positioning tasks – especially in the SIMATIC PLC <br />
environment – can therefore be found using SINAMICS S120 <br />
AC Drives even without in-depth knowledge of drives. <br />
Because it is so easy to combine SINAMICS S120 AC Drives <br />
with other SINAMICS S120 units, multi-axis groupings can be <br />
extended comfortably and economically.<br />
Modular machine components can thus be adapted to high <br />
levels of integration and flexibility in line to varying customer <br />
requirements.<br />
Flexibility through modularity<br />
Every SINAMICS S120 AC Drive is a combination of a Power <br />
Module and a selectable Control Unit or Control Unit Adapter. <br />
An optional filter can also be integrated. <br />
If the AC Drive is operated as a stand-alone single-axis drive, <br />
a Control Unit (e.g. CU310 DP) is added to the Power Module. <br />
It contains the entire control intelligence for the drive, including positioning functions and the field bus interface.<br />
If the AC Drive is combined with other SINAMICS S120 units <br />
to build an integrated multi-axis drive solution, a CUA31 Control Unit Adapter is added to the Power Module in order to <br />
connect the AC Drive to a central Control Unit (e.g. CU320 or <br />
SIMOTION D) via the DRIVE-CLiQ interface in accordance with <br />
the SINAMICS S120 system architecture. <br />
With SINAMICS S120 the modular expansion of your machines <br />
is never limited. Cost-optimized and specific solutions are <br />
ensured since only the components and functions required for <br />
a perfect fit solution are used.</div>Bloggerhttp://www.blogger.com/profile/02093150578229231253noreply@blogger.com0tag:blogger.com,1999:blog-7409540096668448495.post-61249434700157010782011-08-17T05:07:00.003-07:002012-11-05T06:38:56.741-08:00SINAMICS S120 – technical data<div dir="ltr" style="text-align: left;" trbidi="on">Modules and expansion options:<br />

Complete drive groups can be interlinked <br />
and assembled using the SINAMICS S120 <br />
Cabinet Modules and Chassis units. This <br />
is because it is possible to combine module types with freely selectable power <br />
ratings as required. Fast and straightforward, due to the standard interfaces that <br />
are harmonized with one another.<br />
For paper machines, rolling mills, test <br />
stands and cranes – that typically require <br />
multi-motor applications with high power <br />
ratings, both the modular cabinet units as <br />

solution as part of a modular system.<br />
The highly flexible, modular system follows the trend to shift intelligence into <br />
the drive, which is achieved using its harmonized, standard interfaces. Planning is <br />
simplified and reliability increased thanks <br />
to the ready-to-connect cabinet solution <br />
with several Cabinet Modules. The chassis <br />

Increasingly, complex motion control <br />
tasks must be handled in machinery <br />
construction and at the same time, they <br />
must be able to run even more precisely <br />
and faster. This is where the SIMOTION <br />
motion control system and the high-performance SINAMICS S120 drive system <br />
form a perfect team. SIMOTION D, the <br />
version that is physically integrated into <br />
the SINAMICS S120 drive, is the ideal solution for machines with a high number <br />
of axes and where high requirements are <br />
placed on the precision. This distributed <br />
automation structure allows the machine <br />
to be subdivided into various axis groups <br />
that are controlled from one SIMOTION <br />
motion control system. Communications <br />
between SIMOTION systems is either established via PROFIBUS DP or PROFINET. <br />
In this case, there is another important <br />
aspect – the compact machine design, <br />
which is due to the distributed automation structure and the Motion Control <br />
Unit that is directly integrated in the <br />

AC Drives for <br />
single-axis applications<br />
• An autonomous single-axis <br />
SINAMICS S120 AC Drive comprises <br />
a Control Unit and Power Module<br />
• Alternatively, a Power Module can <br />
be integrated into a multi-axis <br />
group via CU adapter<br />
• Power Modules are available in the <br />
Blocksize and Chassis formats<br />
Typical applications<br />
Single-axis drives are suitable for applications in all sectors, such as e.g. for travel <br />
drives, centrifuges, elevators and extruders as well as for mixers and kneaders.<br />
Single-axis SINAMICS S120 AC Drives are <br />
also the ideal solution for multi-axis applications where the drive axes are located remotely from one another. The same <br />
applies to modular machine concepts <br />
that are being increasingly implemented <br />
in the packaging and woodworking industries.<br />
For a single-axis drive, the line supply <br />
infeed and the power supply of the motor are combined in one device – the <br />
so-called Power Module. For single-axis <br />
applications, a special Control Unit (e.g. <br />
CU310) mounted on the Power Module <br />
handles the drive control; for multi-axis<br />
applications a Control Unit is used (e.g. <br />
CU320) coupled through DRIVE-CLiQ. <br />
In the latter case, instead of the Control <br />
Unit, a CU Adapter is mounted on the <br />
Power Module. <br />
For instance, SINAMICS S120 AC Drives <br />
decentrally coupled to a higher-level <br />
control via PROFIBUS DP or PROFINET can <br />
reliably handle e.g. positioning tasks in <br />
automated assembly machines and handling systems. <br />

The modular system for highperformance applications<br />
The innovative SINAMICS S120 hardware <br />
and software concept tackles sophisticated drive tasks in industrial applications <br />
with a power range extending from 0.12 <br />
through to 4,500 kW:<br />
SINAMICS S120 offers high-performance <br />
individual AC/AC drives in the Blocksize <br />
and Chassis formats as well as coordinated DC/AC drives for multi-axis applications in the Booksize Compact and Chassis formats and Cabinet Modules.<br />
Increased flexibility with central <br />
control intelligence<br />
For SINAMICS S120, the drive intelligence <br />
is combined together with the control <br />
functions in Control Units (CU), which <br />
handle both vector and servo control as <br />
well as V/f control. For all drive axes, they <br />
also handle the speed and torque control <br />
as well as additional intelligent drive <br />
functions.<br />
Performance can be freely selected for <br />
vector and servo controls<br />
SINAMICS S120 vector control is recommended for drive solutions involving continuous material webs – for instance, <br />
wire drawing, foil making and paper machines – as well as for hoisting gear, centrifuges and marine drives with harmonious, rotary motion. Servo control with <br />
SINAMICS S120 is used for cyclic processes with precise and fast closed-loop <br />
position control using servomotors. For <br />
instance, this includes applications in the <br />
packaging and printing industries as well <br />
as machine tools.</div>

concepts to be created, which can be <br />
used to quickly implement specific <br />
customer requirements.<br />
The response to increasing demands <br />
Today, machines must be able to be <br />
manufactured more cost-effectively and <br />
at the same time they should offer operating companies increasingly higher levels <br />
of productivity. The SINAMICS S120 drive <br />
concept fulfills both of these tasks! Engineering times are shortened due to the <br />
fact that it can be engineered in a userfriendly fashion. Its high dynamic performance and accuracy permits higher cyclic <br />
machine rates for a maximum <br />
degree of productivity. Not only this, its <br />
simple handling and maintenance increases the degree of availability and reduces the life cycle costs. When considering <br />
everything: SINAMICS S120 increases the <br />
competitiveness of both machine manufacturers and operating companies. <br />
Modularity for machine construction<br />
SINAMICS S120 allows power and control <br />
performance to be freely combined. <br />
Multi-axis drive solutions with higherlevel motion control can be implemented <br />
using the modular SINAMICS S120 drive <br />
system just the same as solutions involving single-motor drives. This means that <br />
the machines can be designed to be <br />
fully modular therefore addressing the <br />
growing number of different versions. <br />
Where modules or individual components <br />
are to be combined or innovated, <br />
SINAMICS S120 guarantees the perfect <br />
compatibility between all of the system <br />
components without requiring any major <br />
engineering costs.<br />
Applications in machine and plant <br />
construction<br />

cyclic and high-dynamic processes, for <br />
instance in:<br />
• Packaging machines<br />
• Plastics machines<br />
• Textile machines<br />
• Printing machines<br />
• Paper machines<br />
• Handling and assembly systems<br />
• Machine tools<br />
• Rolling mills<br />

Digital microprocessor-controlled power converter technology, both for DC and AC drives, has<br />
now reached a level of technical sophistication<br />
which (in purely technological terms) enables<br />
almost any drive job to be handled both with DC<br />
and AC drives. Nevertheless, the conventional<br />
DC drive (in both its 1-quadrant and 4-quadrant<br />
variants) will continue to play an important role,<br />
for technical and physical reasons alike, when<br />
dynamic drives with a constant load torque and<br />
stringent requirements for overload withstand<br />
capability throughout a large speed setting range<br />
are involved.</div>

The motor constant makes it possible to design the nominal point of DC motors corresponding to the process requirements.<br />
However the efficiency of AC motors is better (> 55 kW: approx. 1 ... 4 % depending on cooling method).<br />
DC motors are often utilized according to insulation class H. Standard AC motors are used to be utilized according to insulation<br />
class B. This results in a possible higher efficency with AC motors.</div>

The historical development of the DC motor as an electric variable-speed drive since the beginning of the twenties has meant<br />
that DC motors are customarily used with internal/forced ventilation (approx. 85 % of VSDs ≤ 250 kW).<br />
For variable-speed AC drives, asynchronous standard motors have predominantly been utilized since the 70s/80s, which mostly<br />
feature surface ventilation (approx. 90 % of VSDs ≤ 250 kW). Thus the process of matching the three-phase standard motors<br />
to the requirements applying for variable-speed drives with AC converters has not yet been concluded.<br />
The fact that AC motors with ratings of up to approx. 1400 kW are supplied in degree of protection IP 54 as standard is a tribute<br />
to their simple and sturdy construction. For drive jobs in hazardous areas, explosion-protected AC motors are used almost<br />
exclusively. This means that the AC motor has won itself a firm position and proved its practical utility most especially in those<br />
sectors of industry characterized by aggressive ambient conditions and a high degree of dirt and dust in the cooling air.</div>
