ET 200S motor starters in the ET 200S I/O system

The SIMATIC ET 200S is the multifunctional and finely modular I/O system in degree of protection IP20 for exact adaptation to the automation task.

Interface modules (IM) are used for connecting the ET 200S to PROFIBUS DP or PROFINET. If interface modules with integrated S7-CPU are used, the ET 200S can act as a small control system.

The ET 200S is designed for combining with a large range of digital and analog input or output modules, technology modules, IO-Link master modules, pneumatic connections, or motor starters and frequency converters for the control of drives.

Besides the standard variants, SIPLUS variants are available for both the interface modules and the peripheral modules. These can be used for an extended temperature range and increased media load.

Device replacement is easy and quick thanks to permanent wiring and automatic re-parameterization.

Hot swapping, i. e. the disconnection and connection of modules without prior isolation, guarantees high availability of the automation system along with extensive diagnostics information.

The ET 200S motor starters are connected to the control system and parameterized through the fieldbus using either PROFIBUS or PROFINET via IM modules – available in both standard and safety-related versions.

With the ET 200S motor starters, any AC loads can be protected and switched. The communications interface makes them ideal for operation in distributed control cabinets or control enclosures.

Innovation of the ET 200S High Feature motor starters

The ET 200S High Feature motor starters have undergone radical innovation and now support the acyclic services on PROFIBUS and PROFINET as well as PROFIenergy on PROFINET.

They are now:

• Even more flexible – flexible assignment of parameters
• Even better integrated in TIA (Totally Integrated Automation)
• Even more transparent – through comprehensive diagnostic data records
• Even more anticipatory – through maintenance functions
• Energy-efficient – through PROFIenergy

Basic functionality of the ET 200S motor starters

All variants of the ET 200S motor starters have the following functionality. The further specific functionality is described for the respective variants.

• Fully pre-wired motor starters for switching and protecting any AC loads up to 7.5 kW at 400 V AC and 500 V AC
• With self-assembling 40/50 A power bus, i. e. the load voltage is only supplied once for a group of motor starters
• Only connected once all module supply voltages, i. e. when Anreihen connected automatically with the next module
• Hot swapping is permissible
• Inputs and outputs for activating and signaling the status have been integrated
• Control of the motor starter from the control system and extensive diagnostics status via the cyclic process image
• Diagnostics capability for active monitoring of the switching and protection functions
• The signal states in the process image of provide information about motor starter protective devices (short-circuit or overload), the switching states of contactor(s) or soft starters, and system faults.
• Interface for controlling an expansion module, e.g. brake control module xB1 ... xB4 for controlling mechanical brakes in three-phase motors for 24 V and 500 V DC.
• Brake control module xB5 and xB6 for 400 V AC
• For combining with safety technology for use in safety-related system components (IEC 62061 and ISO 13849-1).

Mounting

As the motor starters are fully pre-wired, up to 80% of the wiring effort can be saved. The control cabinets can be assembled far more quickly and compactly.

Expansions are easily possible through the subsequent adding of terminal modules. With their modular terminal design (10 mm?) the latter also do away with the distribution wiring otherwise required. Through the permanent wiring and the "hot swapping" function (disconnection and connection during operation) a motor starter can be replaced within seconds if necessary. The motor starters are therefore recommendable in particular for applications with special demands on availability.

Planning and configuration

Configuration is made easier by the fine modular structure.

When using the ET 200S motor starters, the list of parts per load feeder is reduced to two main items: The passive terminal module and the motor starter. This makes the ET 200S ideal for modular machine concepts as well.

All ET 200S motor starters are set up without fuses. Contactors and soft starters are activated through the integrated outputs. The inputs of the motor starters evaluate the signal states of the protective devices (short circuit or overload), the switching states of contactor(s) or soft starters, and system faults.

The motor starter protector signaling is freely programmable with regard to group fault signals (group fault at motor starter protector "Off"/group fault signal at motor starter protector "Off" only in case of "On" command from the motor starter).

Brake control modules and optional digital inputs and outputs

With one of the optional brake control modules (xB1-xB6), which is butt-mounted to the right of a motor starter, it is possible to control a mechanical holding brake on a three-phase motor from the process image of the motor starter.

Motors with 24 V DC brakes (xB1, xB3) as well as motors with 500 V DC brakes (xB2, xB4) can be controlled using the brake control modules xB1-xB4.

The modules xB5 (without digital input) and xB6 (with two digital inputs) have been added to the range in order to control a mechanical holding brake with a rated operational voltage of 400 V AC. A further motor brake voltage commonly found on the market is thus supported.

The 24 V DC brakes have an external supply and can be vented independently of the switching state of the motor starter. By contrast the 500 V DC brakes and the 400 V AC brakes mostly have a direct supply from the terminal board of the motor through a rectifier module and therefore cannot be vented when the motor starter is switched off. These brakes cannot be used in combination with the DSS1e-x motor starter (soft starter).

Alternatively, the outputs of the brake control modules can be used for other purposes, such as for controlling DC valves.

With two digital inputs available on the brake control modules (xB3, xB4, xB6) and another two digital inputs available on the optional control module it is possible to realize autonomous special functions which work independently of the bus and the higher-level control system, e.g. as a quick stop on gate valve controls. The signals of these digital inputs are in the process image and are reported to the control system.

Power supply through terminal module

Power is supplied through the terminal modules for motor starters:

• the auxiliary voltages are fed in only once via the PM-D or PM-DFx power module which must be connected to the left of the first motor starter.
• The load voltage is fed in at the first (left) TM-xxxxS32 terminal module of a motor starter. The other TM-xxxxS31 terminal modules are automatically supplied with power as well through the integrated power bus when they are mounted side by side.
  If the power bus is utilized to its full capacity of 40 A or 50 A for High Feature motor starters, a new supply is fed in through an additional TM-xxxxS32 terminal module.

Terminal modules for TM-DS and TM-RS motor starters

• Mechanical modules in which the motor starter and expansion modules are inserted
• For constructing the permanent wiring and self-assembling voltage bus
• For connecting the motor connection cables
• Positive-locking connection to ensure enhanced vibration resistance

Terminal modules are purely mechanical components for accommodating the ET 200S peripherals. The self-assembling voltage buses integrated in the terminal modules reduce wiring outlay to the single infeed (both from auxiliary as well as load voltage). All modules following on the right are automatically supplied upon plugging the terminal modules together. The robust design and keyed connection technology enables use in harsh industrial conditions.

The TM-DS and TM-RS terminal modules are available in various versions for the Standard motor starters and the High Feature motor starters.

Terminal modules with the suffix "-S32"

• The terminal modules with the suffix "-S32" have connection terminals for feeding into the integrated 40A/50A power bus and connection terminals for the motor connection cable. They are mounted at the beginning (left) of a power bus segment.
• To configure a new load group, another "-S32" terminal module is plugged in.
• The "-S32" terminal modules are supplied with three caps for closing the power bus contacts on the final terminal module of a segment.
• Optionally expandable with PE/N blocks

Terminal modules with the suffix "-S31"

• The terminal modules with the suffix "-S31" have only connection terminals for the motor connection cable. These terminal modules follow on the right after a "-S32" terminal module.
• Optionally expandable with PE/N blocks

All connection terminals of the terminal modules for motor starters are equipped with strong 10 mm? screw terminals.

Power modules

PM-D power modules are used for monitoring the two 24 V DC auxiliary voltages for the group of motor starters following on the right or for supplying power to the group of frequency converters following on the right.
