SINAMICS S120

 

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 digital system interface DRIVE-CLiQ.
 
Control Units
CU310 DP, CU320 and SIMOTION D4x5 Control Units


CU310 DP and CU310 PN Control Unit
CU310 Control Units are designed to control a single drive. They feature as standard a PROFIBUS interface (CU310 DP) or PROFINET interface (CU310 PN) and a TTL/HTL encoder evaluation circuit.

CU320 Control Unit
The CU320 Control Unit has been designed to control multiple drives. A CU320 is capable of operating up to
8 drives in V/f Control mode or
6 drives in Servo Control mode or
4 drives in Vector Control mode.
The CU320 Control Unit can be used to create links between individual drives and implement simple technology functions.

SIMOTION D Control Units
A SIMOTION D Control Unit is used for applications requiring coordinated motion control such as synchronous operation, electronic gear, cam disk or complex technology functions.
SIMOTION D Control Units are available in a range of performance variants:
SIMOTION D410 for controlling 1 axis
SIMOTION D425 for controlling up to 16 axes
SIMOTION D435 for controlling up to 32 axes
SIMOTION D445 for controlling up to 64 axes
The STARTER commissioning tool is used to commission and diagnose the various types of Control Units. The SCOUT engineering system, which includes the STARTER tool, is required for SIMOTION D Control Units. For further information about STARTER and SCOUT, see Engineering Software.
 
Power Modules
The stand alone version of a SINAMICS S120 drive system consists of a CU310 or D410 Control Unit and a Power Module. A mains rectifier, a voltage-source DC link and an inverter for supplying a motor are integrated in the Power Module. Power Module in blocksize format with CU310 DP Control Unit Power Modules are designed for single drives which are not capable of regenerating energy to the supply. Generated energy produced during braking is converted to heat via braking resistors.
Power Modules can also be operated by a CU320 or a SIMOTION D4x5 Control Unit, e.g. in configurations where a single drive has been added to a multi-axis drive grouping. In this case, the Power Modules of the booksize format must be equipped with the CUA31/CUA32 control unit adapter. This is connected with the CU320 or SIMOTION D4x5 Control Unit using DRIVE-CLiQ. Power Modules in chassis format can be directly connected to the mullti-axis Control Unit using a DRIVE-CLiQ cable.
 
Motor Modules
A voltage-source DC link and an inverter for supplying a motor are integrated in the Motor Module.
CU320 Control Unit, Line Module and two Motor Modules in booksize format Motor Modules are designed for multi-axis drive systems and are controlled by either a CU320 or a SIMOTION D4x5 Control Unit. Motor Modules are interconnected by means of a shared DC busbar. 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 voltage-source DC link is suppied with line voltage by a Line Module.
 
Line Modules
Line Modules generate a DC voltage from the line voltage and supply Motor Modules with energy via the voltage-source DC link.
 
Basic Line Modules
Basic Line Modules are designed only for infeed operation, i.e.
they are not capable of recovering regenerative energy to the supply system. If regenerative energy is produced, e.g. when drives brake, it must be converted to heat by means of a Braking Module and a braking resistor.
When a Basic Line Module is used as the infeed, the matching line reactor must be installed. A line filter can be installed optionally to restrict conducted interference to Class C2 limits (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). When a Smart Line Module is used as the infeed, the matching line reactor must be installed. A line filter can be installed optionally to restrict conducted interference to Class C2 limits (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, however, Active Line Modules generate a regulated DC voltage which remains constant despite fluctuations in the line voltage. In this case, the line voltage must remain within the permissible tolerance range. Active Line Modules draw a virtually sinusoidal current from the supply which limits any harmful harmonics.
