Chassis Format Units


Overview



With its separate power unit and Control Unit, the SINAMICS S120 drive system can be perfectly adapted to a wide variety of different drive tasks.
 

The Control Unit is selected according to the number of drives to be controlled and the required performance level, while the power unit must be rated to meet the energy requirements of the system. The connection between the Control Unit and power unit is made very simply using the DRIVE-CLiQ digital system interface.
 

The following drive units are available in the chassis format:

- Power Modules
- Basic Line Modules
- Smart Line Modules (only available in the air-cooled version)
- Active Line Modules
- Active Interface Modules
- Motor Modules
 

Power Modules

The simplest version of a SINAMICS S120 drive system comprises a CU310‑2 Control Unit and a Power Module.
 

In Power Modules specifically designed for single drives without regenerative feedback into the line supply, the line-side infeed and the motor-side power unit are combined in one unit.


Generated energy produced during braking is converted to heat in braking resistors.

The Control Unit is plugged onto the Power Module; in addition to the complete control intelligence, the Control Unit also has all the drive interfaces for communication with higher-level systems and interfacing of add-on components.
 

Line Modules

Line Modules contain the central line infeed for the DC link. Various Line Modules can be selected to address the various application profiles:

- Basic Line Modules
- Smart Line Modules
- Active Line Modules


Basic Line Modules

Basic Line Modules are designed only for infeed operation, i.e. they are not capable of recovering energy to the line supply. If regenerative energy is produced, e.g. when drives brake, it must be converted into heat using a Braking Module and a braking resistor.
A line filter can be optionally installed in order to ensure compliance with the limits stipulated for Category C2 in EN 61800‑3.


Smart Line Modules

Smart Line Modules can supply energy and return regenerative energy to the supply system. A Braking Module and braking resistor are required only if the drives need to be decelerated in a controlled manner after a power failure (i.e. when energy cannot be recovered to the supply). For an infeed using a Smart Line Module, the appropriate line reactor is required.

A line filter can be optionally installed in order to ensure compliance with the limits stipulated for Category C2 in EN 61800‑3.


Active Line Modules

Active Line Modules can supply energy and return regenerative energy to the supply system. A Braking Module and braking resistor are required only if the drives need to be decelerated in a controlled manner after a power failure (i.e. when energy cannot be recovered to the supply).
 

In contrast to Basic Line Modules and Smart Line Modules, Active Line Modules generate a controlled DC voltage that is kept constant despite fluctuations in the line supply voltage if the line supply voltage fluctuates within the permitted tolerance range. Active Line Modules draw a virtually sinusoidal current from the supply which limits any harmful harmonics. All of the components necessary to operate an Active Line Module are integrated in the Active Interface Module.

A line filter can be optionally installed in order to ensure compliance with the limits stipulated for Category C2 in EN 61800‑3.


Motor Modules

A voltage DC link and an inverter for supplying a motor are integrated in the Motor Module.


Motor Modules are designed for multi-axis drive systems and are controlled by either a CU320‑2 or a SIMOTION D Control Unit. Motor
Modules are interconnected through the DC link.
 

One or several Motor Modules are supplied with energy for the motors via the DC link. Both synchronous and induction motors can be operated.
 

Since the Motor Modules share the same DC link, they can exchange energy with one another, i.e. if one Motor Module operating in generator mode produces energy, the energy can be used by another Motor Module operating in motor mode. The DC link is supplied with line supply voltage by a Line Module.
 

Control Units

The control intelligence for all the drive axes integrated in the multi-axis group is combined in the Control Units. They also feature drive-related inputs/outputs and interfaces for communicating with higher-level controllers. Control Units are available with different ranges of functions and with different performance levels.
 

System components

The structure of the drive system is defined by selecting the Control Unit and Power Module or Line Module and Motor Modules. The additional components provided allow optimum adaptation of the drive system to the application.
 

These components are subdivided into:

- Line-side components, e.g. line reactors and line filters
- DC link components e.g. Braking Modules and braking resistors
- Motor-side components, e.g. motor reactors and dv/dt filters plus VPL, sine-wave filters
- Supplementary system components, e.g. Terminal Modules, Operator Panels, and Communication Boards
- Encoder system interface for connecting various encoder types to SINAMICS S120
 

DRIVE‑CLiQ – the digital interface between the components

SINAMICS S120 components, including motors and encoders, are equipped with the high-performance DRIVE‑CLiQ system interface.
Line and Motor Modules for example are connected to the Control Unit – and Terminal Modules and Sensor Modules to the drive system via DRIVE‑CLiQ – simply and efficiently. Motors that also have this interface can be directly connected to the drive system.
 

Converter boards (Sensor Modules) for converting standard encoder signals to DRIVE‑CLiQ are available for third-party motors or retrofit applications.
 

The electronic rating plate

An important digital linkage element of the SINAMICS S120 drive system are the electronic rating plates integrated in every component. They allow all drive components to be automatically identified via the DRIVE‑CLiQ link.
 

The electronic rating plate contains all the relevant technical data about that particular component. In addition to the technical data, the electronic rating 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.
 

Painted modules

The following devices are equipped as standard with coated modules:

- Blocksize format units
- Booksize format units
- Chassis format units
- Control Units
- Sensor Modules
- Terminal Modules
- Advanced Operator Panel (AOP30)

The coating on the modules protects the sensitive SMD components against corrosive gases, chemically active dust and moisture.
 

Nickel-plated busbars

All of the copper busbars used are nickel-plated in order to achieve the best possible immunity to environmental effects. Further, it is possible to eliminate having to clean the contacts at the customer connections, which is required for bare copper connections.


Note:

For some components, parts of the copper busbars cannot be nickel-plated for technical reasons.

 

Function

Communication with higher-level controller and customer terminal block

As customer interface to a higher-level control, as standard there is a PROFIBUS or PROFINET communication interface on the Control Unit CU320-2; there are also expansions such as the Terminal Module TM31, the Terminal Board TB30 and modules to communicate via CANopen or EtherNet/IP.
 

These interfaces can be used to connect the system to the higher-level controller using analog and digital signals, or to connect additional units.
 

For additional information, please refer to the SINAMICS Low Voltage Engineering Manual.
 

Open-loop and closed-loop control functions

SINAMICS S120 can use a dynamic, high-precision closed-loop vector control (drive object type VECTOR), or a highly dynamic closed-loop servo control (drive object type SERVO).
 

Software and protective functions

The software functions available as standard are described below:

Software and protective functions

Description

Setpoint input

The setpoint can be specified both internally and externally; internally as a fixed setpoint, motorized potentiometer setpoint or jog setpoint, externally via the communications interface or an analog input. The internal fixed setpoint and the motorized potentiometer setpoint can be switched or adjusted via control commands from any interface.

Motor identification

The automatic motor identification function makes commissioning faster and easier and optimizes closed-loop control of the drive.

Ramp-function generator

A user-friendly ramp-function generator with separately adjustable ramp-up and ramp-down times, together with adjustable rounding times in the lower and upper speed ranges, allows the drive to be smoothly accelerated and braked. This results in a good speed control response and contributes to the reduction of stress on the mechanical system. The down ramp can be parameterized separately for a quick stop.

Vdc max controller

The Vdc max controller automatically prevents overvoltages in the DC link, if the set down ramp is too short, for example. This may also extend the set ramp-down time.

Note: This function only makes sense for single-axis applications.

Kinetic buffering (KIP)

For brief line supply failures, the kinetic energy of the rotating drive is used to buffer the DC link and therefore prevents fault trips. The drive converter remains operational as long as the drive can provide regenerative energy as a result of its motion and the DC link voltage does not drop below the shutdown threshold. When the line supply recovers within this time, the drive is again bumplessly accelerated up to its setpoint speed.

Automatic restart

The automatic restart switches the drive on again when the power is restored after a power failure, and ramps up to the current speed setpoint.

Flying restart

The flying restart function allows the converter to be switched to a motor that is still turning. With the voltage sensing capability provided by the optional VSM10, the flying restart time for large induction motors can be significantly reduced because the motor does not need to be de-magnetized.

Technology controller (PID)

Using the technology controller (PID controller) function module, level or flow controls and complex tension controls can be implemented, for example. The existing D component can act both on the system deviation well as on the actual value (factory setting). The P, I, and D components are set separately.

Free function blocks (FFB)

Using the freely programmable function blocks, it is easy to implement logic and arithmetic functions for controlling the SINAMICS drive. The blocks can be programmed at the operator panel or the STARTER commissioning tool.

Drive Control Chart (DCC)

Drive Control Chart (DCC) is an additional tool for the easy configuration of technological functions for SINAMICS. The block library contains a large selection of control, arithmetic and logic blocks as well as extensive open-loop and closed-loop control functions. The user-friendly DCC editor enables easy graphics-based configuration, allows control loop structures to be clearly represented and provides a high degree of reusability of charts that have already been created. DCC is an add-on for the STARTER commissioning tool (see section Engineering tools).

SINAMICS Technology Extensions (SINAMICS TEC)

The SINAMICS TEC are configurable functions or Siemens technologies that can be added to extend firmware functions. These extensions are designed to allow implementation of highly complex, application-specific tasks for various sectors - such as storage and retrieval machines.
Additional information about Technology Extensions (TEC) is provided in section Technology functions.

I2t sensing for motor protection

A motor model stored in the converter software calculates the motor temperature based on the current speed and load. More exact measurement of the temperature, which also takes into account the influence of the ambient temperature, is possible by means of direct temperature measurement using KTY84 sensors in the motor winding.

Motor temperature evaluation

Motor protection by evaluating a KTY84, Pt1000, PTC or Pt100 temperature sensor. When a KTY84 temperature sensor is connected, the limit values can be set for alarm or shutdown. When a PTC thermistor is connected, the system reaction to triggering of the thermistor (alarm or trip) can be defined.

Motor blocking protection

A blocked motor is detected and protected against thermal overloading by a fault trip.

Brake control

"Simple brake control" for control of holding brakes:
The holding brake is used to secure drives against unwanted motion when deactivated.

"Extended brake control" function module for complex brake control, e.g. for motor holding brakes and operational brakes:
When braking with a feedback signal, the brake control reacts to the feedback signal contacts of the brake.

Write protection

Write protection to prevent unintentional changing of the setting parameters (without password function).

Know-how protection

Know-how protection for encrypting stored data, e.g. to protect configuration know-how, and to protect against changes and duplication (with password function).

Web server

The integrated web server provides information about the drive unit via its web pages. The web server is accessed using a web browser via unsecured (http) or secured transfer protocol (https).

 

Power unit protection

Power unit protection

Description

Ground fault monitoring at the output

A ground fault at the output is detected by a total current monitor and results in shutdown in grounded systems.

Electronic short-circuit protection at the output

A short-circuit at the output (e.g. at the converter output terminals, in the motor cable or in the motor terminal box) is detected and the converter shuts down with a "fault".

Thermal overload protection

An alarm is issued first when the overtemperature threshold responds. If the temperature continues to rise, the unit either shuts down or independently adjusts the pulse frequency or output current so that thermal load is reduced. Once the cause of the fault has been eliminated (e.g. cooling has been improved), the original operating values are automatically resumed.

Liquid-cooled units

 

Overview



The SINAMICS S120 liquid-cooled drive units are specifically designed to address the requirements relating to liquid cooling; they are characterized by their high power density and optimized footprint. Liquid cooling dissipates heat much more efficiently than air cooling systems. As a result, liquid-cooled units are much more compact than air-cooled units with the same power rating. Since the heat losses generated by the electronic components are almost completely dissipated by the liquid coolant, only very small cooling fans are required. This means that the devices are quiet in operation. Due to their compact dimensions and almost negligible cooling air requirement, liquid-cooled units are the preferred solution wherever installation space is restricted and/or the ambient operating conditions are rough.
 

Control cabinets with liquid cooling are easy to implement as sealed units with degrees of protection of IP55.

The product portfolio includes the following liquid-cooled SINAMICS S120 built-in units:

- Power Modules
- Basic Line Modules
- Active Line Modules
- Active Interface Modules
- Motor Modules


The associated system components such as line reactors, motor reactors, dv/dt filters plus VPL and sine-wave filters are air-cooled. Active Interface Modules are available in air-cooled and liquid-cooled versions.
 

Highlights of the liquid-cooled units

- Up to a 60 % smaller footprint than air-cooled drive converters
- All main components such as power semiconductors, DC link capacitors and balancing resistors are cooled by the cooling circuit
- Only a low flow rate is required
- Uniform pressure drop of 0.7 bar
- Automatic protective functions
- Nickel-plated busbars
- Low noise
- Compatible with all components and functions and tools of the SINAMICS system family

The manufacturer of the antifreeze/inhibitor should analyze the coolant at least once per annum. The concentration and boundary conditions of the antifreeze/inhibitor should be checked. It may be necessary to correct the concentration on the plant side.
 

Protection against condensation

With liquid-cooled units, warm air can condense on the cold surfaces of heat sinks, pipes and hoses. This condensation depends on the air humidity and the temperature difference between the ambient air and the coolant.
 

The water which is produced as a result of condensation can cause corrosion as well as electrical damage such as creepage shorts and flashovers. As the SINAMICS units cannot prevent condensation if it is caused by the prevailing climatic conditions, any potential risk of condensation must be prevented by appropriate engineering or by precautionary measures implemented by the customer. These measures include the following:

- a fixed coolant temperature that has been adjusted to the expected air humidity or ambient temperature ensures that critical differences between the coolant and ambient air temperatures do not develop or

- temperature regulation of the coolant as a function of the ambient air temperature


The temperature at which water vapor contained in the air condenses into water is known as the dew point. To prevent condensation reliably, the coolant temperature must always be higher than the dew point.


The table below specifies the dew point as a function of room temperature T and relative air humidity Φ for an atmospheric pressure of 100 kPa (1 bar). This corresponds to an installation altitude of 0 up to approximately 500 m (1640 ft) above sea level. Since the dew point drops as the air pressure decreases, the dew point values at higher installation altitudes are lower than the specified table values. It is therefore the safest approach to engineer the coolant temperature according to the values in the table for an installation altitude of zero.

Characteristic curves

Derating

Liquid-cooled SINAMICS S120 chassis format units are rated for an ambient temperature of 45 °C (113 °F) and installation altitudes up to 2000 m (6562 ft) above sea level. At ambient temperatures > 45 °C (113 °F), the output current must be reduced. Ambient temperatures above 50 °C (122 °F) are not permissible. At installation altitudes > 2000 m (6562 ft) above sea level, it must be taken into account that the air pressure, and therefore air density, decreases as the height increases. As a consequence, the cooling efficiency and the insulation capacity of the air also decrease.

Current derating as a function of the temperature of the cooling liquid 1)

Current derating as a function of ambient temperature 1)

1) The factors of the two curves must not be multiplied. The highest value in each case must be assumed for the purposes of calculation, so that the derating factor in the worst-case scenario is 0.9.

Permissible ambient temperature as a function of installation altitude

Voltage derating as a function of installation altitude

Current derating for Power Modules and Motor Modules in chassis format as a function of the pulse frequency

To reduce motor noise or to increase output frequency, the pulse frequency can be increased relative to the factory setting (1.25 kHz or 2 kHz). When the pulse frequency is increased, the derating factor of the output current must be taken into account. This derating factor must be applied to the currents specified in the technical specifications.

For additional information, please refer to the SINAMICS Low Voltage Engineering Manual.

The following tables list the rated output currents of the SINAMICS S120 Power Modules and Motor Modules with pulse frequency set in the factory as well as the current derating factors (permissible output currents referred to the rated output current) for higher pulse frequencies.

Pressure drop

Pressure drop for liquid-cooled built-in units in chassis format

The pressure drop characteristics are valid for water. If antifreeze is used, the characteristics typically shift to the left.

For further information, please refer to the SINAMICS Low Voltage Engineering Manual.
 

Overload capability

Liquid-cooled SINAMICS S120 units have an overload reserve, e.g. to handle breakaway torques. If larger surge loads occur, this must be taken into account in the configuration. For drives with overload requirements, the appropriate base load current must, therefore, be used as a basis for the required load.
 

The permissible overload levels are valid under the prerequisite that the drive units are operated with their base-load current before and after the overload condition based on a duty cycle duration of 300 s.
 

For temporary, periodic duty cycles with high variations of load within the duty cycle, the relevant sections of the SINAMICS Low Voltage Engineering Manual must be observed.
 

Power Modules and Motor Modules

The base-load current for a low overload IL is the basis for a duty cycle of 110 % for 60 s or 150 % for 10 s.

Low overload


The base-load current IH for a high overload is based on a duty cycle of 150 % for 60 s or 160 % for 10 s.

Chi tiết về sản phẩm SINAMICS S120 built-in units > Chassis Format > Liquid-cooled Power Modules

Overview


The Power Module comprises a line rectifier, a DC link and an inverter to supply the motor.


Power Modules are designed for drives that are not capable of regenerating energy to the mains supply. If the motor produces energy during braking, a Braking Module with braking resistors will be required.


Liquid-cooled Power Modules are especially suitable for applications where installation space is restricted and environmental conditions are harsh. Liquid cooling ensures efficient heat dissipation.


Power Modules in the chassis format can be connected to grounded TN/TT systems and non-grounded IT systems.

 

Design

The liquid-cooled Power Modules have the following interfaces as standard:

- 1 line supply connection
- 1 motor connection
- 1 connection for the 24 V DC electronics power supply
- 1 DC link connection
- 3 DRIVE‑CLiQ sockets
- 1 temperature sensor input for KTY84‑130, Pt1000, PTC or Pt100 (Pt1000 can be used from firmware V4.7 HF17)
- 1 connection for Safe Brake Adapter
- 1 connection for Safety Integrated
- 2 PE connections
- 2 coolant connections


The CU310-2 Control Unit can be integrated into the liquid-cooled Power Modules.

The status of the Power Modules is indicated via three LEDs.


The scope of supply of the Power Modules includes:

- 1 DRIVE‑CLiQ cable for connection to the Control Unit
- 2 seals for coolant connections
- 1 set of warning labels in 30 languages 
(BG, CN, CZ, DE, DK, EE, ES, FI, FR, GB, GR, HU, IE, IS, IT, JP, KR, LT, LV, MT, NL, NO, PL, PT, RO, RU, SE, SI, SK, TR)

 

Integration

The Power Modules communicate with the higher-level control module via DRIVE‑CLiQ. The Control Unit in this case could be a CU310-2, CU320-2 or a SIMOTION D Control Unit. An external 24 V DC power supply is required to operate liquid-cooled Power Modules.


Connection example of a liquid-cooled Power Module in the chassis format


Note:

The integrated 24 V power supply at connector X42 can have a maximum load of 2 A. When the Control Unit is supplied from the integrated power supply, the total load of the digital outputs must be carefully observed to ensure that the 2 A is not exceeded.
