Construction of Sinamics Siemens S120

Dear PLC technical members,

Welcome to our followers on the Blog PLC Technicals blog,today we will start together in the lesson of the course SPEED VARIATOR.The educational article shows step by step the construction of the modular inverter siemens SINAMICS S120.

I. Construction of Sinamics Siemens S120

This is the part of introducing the Sinamics S120 high performance and servo drives. In any S120 multi-axis system we have three primary components. The control unit, which is the brains of the system. Then we have the line module that converts the incoming 3 phase power into a common DC bus. 

Next we have one or a series of motor module inverters, which is connected to the common DC bus and supplies power out of the motors 

Although we're showing them physically mounted together, for convenient arc flash compliance it's also common for the control unit, where the user interfaces are located, to be mounted in a low voltage cabinet away from from the line and motor modules.

A key benefit of the Sinamics S120 system is it's self configuration capability made possible with Siemens DRIVE Cliq is the flexible backplane of the S120 system, allowing an easy flexible way to connect all components together. 

Drive ClIQ uses an Ethernet physical layer, and is a dedicated real time communication protocol supporting different topologies providing fast and easy connectivity back to the control unit. The Sinamics S120 system reads all the electronic nameplates of the components and self-configures the system, greatly reducing parameterization and unforced programming errors. 

Motors with Drive CLIQ send both the nameplate data as well as encoder feedback over the same cable. If the motor has a drive Cliq encoder, just connect this back to this motor module. IF the motor does not have drive Cliq, the encoder is typically connected to an SMC module then brought into the Sinamics S120 system. 

Motor power connections are made at the lower side of the motor modules. This is also where the shield connection is made. The 24V DC power is also located behind the hinged teal covers.
An adapter is used to supply the rails, and then by using the supplied jumpers, power is connected to each motor module.

Before closing the teal covers, observe where the end covers will be needed.

2. analysis of errors

1. Sinamics Siemens S120

General

• Modular structure with multiple 
• applications Central 
• Power supply unit Common intermediate circuit for all drive components, energy exchanges between controls
• Drive-CLIQ single link of drive components

Power flow

• Power unit

• SLM Smart Line Module
• ALM Active Line Module
• Intermediate circuit UZK= 1,5 *EU
• Engine modules

Drive-cliq:

• Connection between the various drive components
• Real-time data exchange
• Single communication system
• Cable type CAT5 with additional wires for 24V power supply

2. ANALYSIS OF ERRORS

2.1 Analysis of Error CU320-2 dp

DEL	STATE	DESCRIPTION
RDY	Green	Marche
	Red 2 Hz	General error
	Shut down	No power supply
DP1	Green	Ongoing communication
	Red 2 Hz	Communication interrupted
OPT	Green	Optional module operation

The Control Units (Blocs de réglage) process the technological functions between the drives and the axes and allow a central link with the primary controls.

• PROFIBUS link with primary control
• DRIVE-CLIQ link with drive modules
• Configuration and commissioning by STARTER
• Integration into the Step7 project

2.2 Analysis of Error (Motormodule,Linemodule)

STATE		DESCRIPTION
RDY	DC LINK	In working order, communication in progress
Green	Shut down	In working order, presence UZK
	Orange	In working order, UZK too high
	Red	No power supply
Shut down	Shut down	Device fault
Red		In working order, communication in progress

• The Motormodules work as an inverter and power the connected motors.
• Line modules provide central power to the intermediate circuit and power recovery and equalize the network variations.

2.3 Analysis of Error  SMC30

SMC30 – Pulse Generator Interface

DEL	STATE	DESCRIPTION
RDY	Green	In working order, communication in progress
	Orange	Communication in progress
	Red	Failed module
	Shut down	No power supply
OUT >5V	Orange	Presence of electronic power supply to the sensor system
	Shut down	No power supply
