INTRODUCTION TO TATA STEEL• Tata Steel is among the top ten global steel

companies with an annual crude steel capacity of over 28 million tonnes per annum.

• The total revenue of Tata companies was 67.4 billion USD (around Rs319,534 crore) in last year.

• Other Group Companies in the different sectors are – Tata Motors, Tata Consultancy Services (TCS), Tata Communications, Tata Power, Indian Hotels, Tata Global Beverages and Tata Chemicals.

BASIC FUNCTION OF BALDOR DRIVE• Baldor drive is used to drive the motor. Baldor

drive is used to control the torque and speed of the motor. This drive is prepared by Baldor Electric Company, USA. Baldor drive convert AC line power to fixed DC power. The baldor series 15H control may be used in different applications. We can use this drive in 11 different operating modes for custom operation. The user have to determine the optimum operating zone and operating mode for the application.

OPERATING MODES OF BALDOR DRIVE

We can also use this drive in 11 different operating modes for custom operation.• 15 speed, 2 wire control• Fan pump 2 wire control mode• Fan pump 3 wire control mode• Serial• Process control• 3 speed analog 2 wire• 3 speed analog 3 wire• Electronic potentiometer 2 wire• Electronic potentiometer 3 wire• Standard run, 3 wire control• Keypad operating mode

• These operating modes define the basic motor control setup and the operation of the input and output terminals. These operating modes are selected by programming the Operating Mode parameter in the Input programming Block. Each mode requires connections to the J4 terminal strip (except the keypad mode, all connections are optional). The J4 terminal strip is shown in next slide.

CONTROL BOARD JUMPER

PROGRAMMING AND OPERATION

• The keypad is used to program the control parameters, to operate the motor. We use Keypad for enter programming in drive and set the parameter value in drive according to output.

TROUBLESHOOTING• The Baldor Series 15H Control requires very little

maintenance. Occasional visual inspection and cleaning should be considered to ensure tight wiring connections and to remove dust, dirt, or foreign debris which can reduce heat dissipation. Operational failures called “Faults” will be displayed on the keypad display as they occur..

• Before contacting Baldor, check that all power and control wiring is correct and installed according to the recommendations in this manual.

FAULT MESSAGE DESCRIPTION• Invalid Base ID• Low Bus Voltage• High Surge Current• Ground Fault• Power Supply Failure• Bus Under Voltage• Bus Current Sense failure• Over Current• 1 Min Over Load• 3 Sec Over Load……………………..

SIEMENS DRIVE• Siemens made different series of drive. The

different series are as follows:- • Low Voltage Drive- Drive Sinamics G110, Sinamics G120, Sinamics G120D, Sinamics G130, SinamicsG150, Sinamics S120, Sinamics S150.• Medium Voltage Drive- Sinamics GM150, Sinamics SM150, Sinamics GL150.

SIEMENS G120 DRIVE• SINAMICS G120 is part of the SINAMICS drive

family for innovative and leading-edge drive solutions. SINAMICS G120 is the universal drive in the complete industrial and trades areas, in sectors such as machinery construction, automobile, textiles, printing and packaging, chemical industry as well as in higher-level applications such as in conveyor technology, in the steel, oil & gas and offshore sectors as well as in renewable energy applications.

SIEMENS G120

WHY WE USE SIEMENS DRIVE• Wide range of power ratings from 0.12 kW to 120 MW• Both in low-voltage as well as medium-voltage versions• High degree of flexibility and the ability to be combined• SINAMICS offers the optimum drive for every drive

application– and all drives can be configured, parameterized, commissioned, and operated in a similar manner.

• Direct integration in the inverter • Higher performance• Easy to handle• Numerous combinations of PM and CU are possible

APPLICATION

• As a universal drive in all industrial and

commercial applications• In the automotive, textiles, printing, and chemical

industries• For end-to-end applications, e.g. in conveyor

systems.
