General information
2.2 Platform Concept and Totally Integrated Automation
Depending on the application, the SINAMICS range offers the ideal variant for any drive
task.
● SINAMICS S handles complex drive tasks with synchronous motors and induction motors
and fulfills stringent requirements regarding:
– the dynamic performance and accuracy
– the integration of extensive technological functions in the drive control system
● SINAMICS G is designed for standard applications with induction motors. These
applications have less stringent requirements regarding the dynamic performance of the
motor speed.
● SINAMICS V is designed to address applications where basic drive functions are
available quickly and at a favorable cost - and which are easy to handle.
2.2 Platform Concept and Totally Integrated Automation
All SINAMICS versions are based on a platform concept. Joint hardware and software
components, as well as standardized tools for design, configuration, and commissioning
tasks ensure high-level integration across all components. SINAMICS handles a wide variety
of drive tasks with no system gaps. The different SINAMICS versions can be easily
combined with each other.
Totally Integrated Automation (TIA) with SINAMICS S120
Apart from SIMATIC, SIMOTION and SINUMERIK, SINAMICS is one of the core
components of TIA. It is thus possible to parameterize, program and commission all
components in the automation system via the Startdrive commissioning tool using a
standardized engineering platform and without any system transitions (seamless
engineering). The system-wide data management functions ensure consistent data and
simplify archiving of the entire plant project.
From V14, the Startdrive commissioning tool is an integral element of the TIA platform.
SINAMICS S120 supports communication via PROFINET and PROFIBUS DP.
Communication via PROFINET
This Ethernet-based bus enables control data to be exchanged at high speed via
PROFINET IO with IRT or RT and makes SINAMICS S120 a suitable choice for integration
in high-performance multi-axis applications. At the same time, PROFINET also uses
standard IT mechanisms (TCP/IP) to transport information, e.g. operating and diagnostic
data, to higher-level systems. This makes it easy to integrate into an IT corporate network.

Modular system for sophisticated drive tasks
SINAMICS S120 solves complex drive tasks for a wide range of industrial applications and
is, therefore, designed as a modular system. You can choose from many different
harmonized components and functions to create a solution that best meets your
requirements. SIZER, a high-performance engineering tool, makes it easier to select and
determine the optimum drive configuration.

2.3 System overview
SINAMICS S120 is supplemented by a wide range of motors. SINAMICS S120 optimally
supports:
● SINAMICS S120M
● Synchronous and induction motors
● Linear and torque motors
System architecture with a central Control Unit
On the SINAMICS S120, the drive intelligence is combined with closed-loop control functions
into Control Units. These units are capable of controlling drives in the vector, servo and V/f
control modes. They also perform the speed and torque control functions plus other
intelligent drive functions for all axes on the drive. Cross-axis couplings can be established
within a component and easily configured in the Startdrive commissioning tool using a
mouse.
Functions for higher efficiency
● Basic functions: Speed control, torque control, positioning functions
● Intelligent starting functions for independent restart after power supply interruption
● BICO technology with interconnection of drive-related I/Os for easy adaptation of the
drive system to its operating environment
● Integrated safety functions for rational implementation of safety concepts
● Regulated infeed/regenerative feedback functions for preventing undesirable reactions on
the supply, allowing recovery of braking energy and ensuring greater stability against line
fluctuations.
DRIVE-CLiQ – the digital interface between SINAMICS components
Most of the SINAMICS S120 components, including the motors and encoders, are
connected to each other via the common DRIVE-CLiQ serial interface. The standardized
cables and connectors reduce the variety of different parts and cut storage costs. Encoder
evaluations for converting standard encoder signals to DRIVE-CLiQ are available for thirdparty motors or retrofit applications.
Electronic rating plates in all components
An important digital linkage element of the SINAMICS S120 drive system are the electronic
type plates integrated in every component. They allow all drive components to be detected
automatically via a DRIVE-CLiQ link. As a result, data does not have to be entered manually
during commissioning or component replacement – helping to ensure that drives are
commissioned more reliably.
The rating plate contains all the relevant technical data about that particular component. For
motors, these are the parameters of the electrical equivalent circuit diagram and key values
of the integrated motor encoder, for example.
In addition to the technical data, the type plate includes logistical data (manufacturer ID,
article number and ID). Since this data can be called up electronically on site or remotely, all
the components used in a machine can always be individually identified, which helps simplify
servicing.

2.6 Time synchronization between the control and converter
2.6 Time synchronization between the control and converter
In the factory setting, SINAMICS S120 drives use an operating hours counter. Based on the
operating hours, SINAMICS S120 saves alarms and warnings that occur. Using this method,
it is not possible to have a comparable timestamp between various converters.
In order to obtain a comparable timestamp between several converters, you must change
over the operating hours counting to time in the UTC format and synchronize with the time
master (control system).
This means that the events of all bus nodes, which are synchronized with the control system
time, can be referenced with one another.
Benefits: Improved diagnostic options by having a comparable time stamp of the bus nodes
involved.
Converters provide the following options to synchronize the time:
Synchronization using ping compensation for non-isochronous communication approx. 10 ms
Principle of operation of time synchronization
Basic synchronization
The control system transfers the time to the converter at time intervals that you specify in the
control system. Transfer is realized acyclically in the UTC format. The converter accepts this
time as soon as transfer has been completed without correcting the transfer duration. The
converter logs alarms and warnings based on this time.
Time synchronization with ping compensation
At intervals that you specify in the control system, the control system sends a ping (a positive
signal edge) cyclically to the converter. Simultaneously, in acyclic operation, the device
sends the time in the UTC format in what is known as "snap".
As soon as the ping has been received in the drive, a timer starts which measures the time
until the snap has been completely transferred. The drive accepts the time that the snap
transfers. It then corrects it by the time that has expired between receiving the ping and the
complete transfer of the snap.
If the snap has not been transferred within 5 s after receiving the ping, then this
synchronization cycle is not used.

Time synchronization via Network Time Protocol (NTP)
Through NTP, all computers worldwide can synchronize their time. An inverter configured as
an NTP client synchronizes the time via a PROFINET connection to an NTP server (a time
source).
As NTP server, the following constellations are possible:
● Local NTP server that receives the time via GPS or DCF77 (e.g. SICLOCK).
● Control as NTP server if the plant network is divided into a control level and a field level.

2.6 Time synchronization between the control and converter
2.6.1 Setting SINAMICS time synchronization
Setting time synchronization
1. Using p3100, changeover the time format from operating hours into the UTC format (see
"Changing the time format").
2. Set the synchronization technique:
– Basic synchronization (p3103 = 2)
– Time synchronization with ping compensation (p3103 = 0)
3. Using p3104, set the ping source:
– If you are working with one of the telegrams 390, 391 or 392, then the source of the
ping (p3104) is internally connected with bit 1 of the CU control word
(DO1:CU_STW.1). In this case, parameter p3104 is blocked.
– If you are using a free telegram (999), interconnect the ping source (p3104) via BICO
in the control word.
– If you are working with CANopen, interconnect a free bit in the CANopen control word
with p3104 via a BICO connection.
Result:
After time synchronization, the current time is obtained from the time transferred by the time
master plus the necessary delay time associated with the transfer (ping-snap time).
The actual UTC time is displayed in the drive system using r3102.
At certain intervals, synchronization (according to the same technique) is repeated
(depending on the setting in the time master).
If a previously defined tolerance window is exceeded, then alarm A01099 is output. Define
the tolerance window for time synchronization using p3109. If alarm A01099 occurs, then
generally the synchronization interval is too long.
In this case, reduce the synchronization interval in your control system.
Changing the time format
The time format is entered via parameter p3100. This parameter cannot be changed online
To change the value, proceed as follows:
1. Connect Startdrive ONLINE with the converter.
2. Carry out an upload using the "Load from device" function.
3. In Startdrive, exit the ONLINE mode.
4. Offline, make the setting p3100 = 1.
5. Reactivate the ONLINE mode.
6. Carry out a parameter download ("Load to device").
7. Save the settings in a non-volatile fashion on the memory card of the drive.
You have now changed over the converter time format to the UTC format.
