Motors are the heart of any plant or industry. The origin of Motor was to convert electrical energy to mechanical energy. DC motor was the first one to be invented and was result of concepts of electromagnetism by Michael Faraday. Today DC Motors , AC Motors - Induction , Squirrel Cage , Servo and Stepper Motor are used widely. We will see in brief about all these different types of Motors used in Automation Industry.
Electrical Motors In Industries :-
1) AC Motor :- We have already discussed the history of AC Motor in our earlier post. There is two broad classification of AC motors first Induction Motor and second as Synchronous Motors.
AC Induction Motor can viewed as Transformer for easy understanding. When voltage is applied to primary of Transformer a current flows and as a result current is induced in secondary winding of transformer.
The primary can be considered as Stator and Secondary as Rotor of AC Induction Motor. The magnetic field set up in the Stator results in Induced Magnetic Field in Rotor and results in Motion. Working of AC Induction Motor discussed already.
Synchronous Motor is same as Induction motor but with different Rotor configuration. The rotor is constructed in such a way that the Rotor is able to rotate with exactly same speed as of stator field. There are two variants of Synchronous Motor - self excited and Directly excited.
2) DC Motors :- DC Motors have been used in Past over the AC motors for applications demanding Speed and Position Control . Until the Introduction of Power electronics the speed variation of DC Motor was easier. In DC Motors the field in stationary in stator and rotor field, is set up by passing current through a commutator and into the rotor assembly. There are different types of DC motors as Shunt Wound Motor, Series Wound Motor and Compound Wound Motor.Subscribe to Automation-Talk by Email
3) Stepper Motor :- As the name indicates Step Motors are used for Converting the Digital Inputs commands in to Analog motion with the help of motor controller electronics.
Stepper Motor Rotates in angular positions according to the digital pulses Inputs. There are different types of Stepper Motors namely as solenoid activated, variable reluctance,permanent magnet and synchronous inductor stepper Motor.
4) PMDC Motor :- PMDC stands for permanent magnet DC , and is mostly used in closed loop system with effective feedback system. In these Motors there is linear speed-torque curve due to permanent magnet which provide provide constant field flux at all speeds. This Motor generates high starting or acceleration torque with light weight and thus used for rapid positioning applications.
5) Servo Motor :- Servo Motor works on servo-mechanism , best for closed loop applications . A controller issue commands for position/speed/torque control of motor shaft. "Servo" is a very big word to understand and we will be discussing more about servo drives, controllers and closed loop system in details in our further posts.

Servo Motor Basics - Closed Loop System
Servo has been a Key Solutions for Applications demanding high accurate and fast positioning closed loop feedback systems. What makes Servo so special? What is there in Servo Motors which cant be done by AC Induction Motors? We will see in this post the functioning of servo motor.
Servo Controller Fundamentals :-
Servo Controller has made possible to reduce the transient response time along with reducing the steady state errors. Better the Transient response time the more is the System bandwidth and thus allowing for faster response and better machine throughput. Less Steady state errors directly indicates for better accuracy.
Below you can see the basic block diagram of servo-mechanism. AC power supplied to Servo System is divided in to two levels as Low and High Level internally by controller electronics section. The low level power is given to Servo Amplifier , which in turn amplifies or increases this signal for motion of servo motor or load.

The low level signals must be amplified as higher voltage is required to rotate the Servo Motor at higher speeds and more current is required for Heavier loads demanding more torque. As we know that Servo System is closed loop System , so when Servo Motor Moves , encoder attached with it also moves and the feedback is received by Controller/Servo Amplifier.
The Servo Controller then looks at this Feedback by Encoder to decide whether the Load is moving properly or not. Suppose for example a command is issued for 5000mm movement of Load and feedback is received for only 4500mm , so controller will issue a command for another 500mm movement. So this is closed loop system and process continues on.
The controller always monitors the Command Signal Issued and the Feedback Signal , they both have t be matched for 100 percent accuracy and zero error. The Command Signal and feedback Signal are compared regularly and corrections are made. So servo is not a single device rather it is a collection of several devices.

How to Find/Limit AC Motor Inrush Current
Inrush current problems while start up of the solid state equipment's as copier, computer and magnetic devices like motor, drives a large amount of current flows and this value of current is several times of steady state value and known as Inrush current. There is no actual known formula for calculation of this Inrush Current value but yes we can determine an approximate value.
When a Motor is started or Transformer energizing takes place then the inrush current can cause a imbalance in the power circuit. However, this inrush current is for few seconds but we should take appropriate actions for this problem.
We will discuss the few major actions which can be adopted to limit the Inrush Current value.
1) Try to keep the Large Ratings Motor on a separate power supply, it will prevent the voltage sag problem.
2) Use Inrush Current Limiting Thermistor, its resistance decreases the temperature increases.
3) Use Series capacitors for distribution circuit of large Rating Motors.
The value of the Inrush Current at start Up can be found out using the Clamp Meter and noting down the measured Value and after that try to use the one of the above method to limit the value. After implementing the method just measure the Value of Inrush Current again and check whether it is reduced or not. Subscribe to Automation-Talk by Email for more articles.

Different Types Of Encoder Used In Automation Industry
In a wide range of Applications in Industrial Automation , One device which is all time favorite for feedback purpose is "Encoder". As it has got capability to be used in Rugged and Noisy Environment , Low cost so still its best choice for feedback purpose and dominates the market.Here in this post we will see about the different output types and Encoder Operating Principle.
||Different Types Of Encoder In Automation Industry||
There are two types of Encoders broadly either in rotary or linear configurations. Every Encoder comes with a predefined PPR and the Maximum Frequency. Let us see how a rotary optical encoder gives the quadrature format. A rotary optical encoder has two output wires as A and B for giving out the quadrature format output. This encoder also Provides the Index pulse for every single rotation completed.
Construction of Rotary Optical Encoder:-
The most common configuration for this type of encoder consists of series of Opaque Parts. The Encoder unit consists of Light Emitting Diode(LED) or Pair of sensor for Giving out the signal for A and B.Now the Opaque Array Segments are arranged in such a way that when it is rotated the A and B signal will be 90 degree to each other. The Index pulse provided after every single rotation of Encoder Shaft can be used for Homing Purpose. See the Below Picture for the overview of Construction part and A , B and I pulses.

Image Source:- automation.com
One of advantage of Index Pulse is used for "auto-correct" feature. The Index pulse will be fixed for the same position of Motor's shaft for every rotation and if there is noise and somehow the number of counts increase or decrease then we can get to know and auto-correct the same.
But with the Incremental Encoders there is a problem ,when we start our system we can't get to now the actual position , so we home the machine . But here comes the another solution and answer is "Absolute Encoders" , with these encoders it is possible to know the actual location every time. These comes in a wide range of Outputs , up to 25 bits.
What is the Difference Between Incremental & Absolute Encoder.
But in earlier time when there were No LED or sensor for Generating the 90 deg offset pulses , non-optical position encoder were used. These are known as "Resolver".The Output of Resolver is in Sinusoidal waveform.
Another Type of Encoder is Magnetic Encoder. The best advantage of this type of Encoder is that the sensor and the encoding disk are not in contact , so it can be rigid packed and a very good solution for noisy and dirty operating conditions.

KEEP Instruction - Omron PLC Programming Tips
Generally, while making the PLC program, we have to use SET and RESET instructions in our PLC program on many rungs. For using SET and RESET we have to write these instructions at two different rungs, and for every BIT that has SET it has to RESET at some condition. In this tutorial, will discuss KEEP instruction, where we can define both above instructions.
There is a better instruction available in CX-Programmer for such situation, CX- Programmer is the software used to program the Omron PLC, which can do your job easy. KEEP is the instruction name and in this instruction, we can define the SET and RESET conditions at same rung.
See the below picture.

Note:- Click on the picture for a clear view.
When W2.0 turns ON, the designated bit will go ON and stay ON until reset, regardless of whether W2.0 stays ON or goes OFF. When W3.0 turns ON, the designated bit will go OFF(w4.0).
KEEP Instruction can be used to create flip-flops as shown below.

Note:- Click on the picture for a clear view.
If a holding bit is used for BIT to be SET, the bit status will be retained even during a power interruption. KEEP can thus be used to program bits that will maintain status after restarting the PLC following a power interruption. An example of this that can be used to produce a warning display following a system shutdown for an emergency situation is shown below.

Note:- Click on the Picture for a clear View.
Important Notes
i) If S and R are ON simultaneously, the reset input takes precedence.
ii) The set input (S) cannot be received while R is ON.

PLC Programming for Printing Machine - Omron Zen PLC
Here in this Post we will see the PLC Programming of a Printing Machine using the Omron Zen PLC. ZEN PLC by Omron is very micro PLC and can be used for small applications. In this Printing Machine there are four inputs and 4 outputs. The Logic of Operation according to the inputs conditions is as follows.
||PLC Programming for Printing Machine - Omron Zen PLC||
In this Printing Machine there are four Inputs and Four Outputs and the PLC Logic as Follows. When the Confirmation Input Is on , then there are Two sensor Inputs for the detection of Paper , these two inputs come at the same time , when these two inputs are on then the Cycle starts. There is One Input for Rotation . When Cycle Starts output Q0 is on and after Two Pulses of Rotation Input output Q1 is on , after 5 pulses Q2 on and after 8 pulses Q3 on. When the Signal for paper detection goes then the output starts becoming off exactly in the same manner as they were ON.
That is the off cycle is as , first Q0 off , after two pulses Q1 off , after 5 pulses Q2 off and after 8 pulses Q3 off. But what if the cycle is started and in between the Paper detection sensor signal goes? Well in this case the Cycle will continue but in a modified form that is outputs will become On one by one. Let us take one example , that cycle is started and when Q0 is on the paper detection signal goes , then after 2 pulse Q1 will on and Q0 will off , and After 5 pulses Q2 will on and Q1 will off and so on.
This application is designed using the Omron Zen PLC , as there are not Typical Instructions available in Zen PLC so the PLC Logic is purely made by Bit Logic. We have included both the.cxp and .pdf files.
Download PLC Program for Printing Machine.
Update :- Many users mailed us saying that the program has got some error , now that bug has been removed and You can Download the latest Version of PLC Program From Below.

PLC Programming For Pump Running Cycle
Pump Running Sequence have to be defined in many applications where we have 4 or 5 pumps and we want the running of 2 or 3 pumps at a time. It may be also possible that we may want to Operate the pump according to the Level. Here in this article we will see the PLC programming for running Sequence of Pump according to level.
PLC Programming For Pump Running Cycle| Pump Running Sequence
Here we will take a example that there is a wet well and 3 pumps are there in the wet well, and there is one Ultrasonic sensor for Level measurement. The operation of Pumps will be according to Cycle , and three cycles are defined as below.
Cycle I - Pump 1 and Pump 2 Run.( Pump 3 on stand By)
Cycle II - Pump 2 and Pump 3 Run.( Pump 1 on stand By)
Cycle III - Pump 1 and Pump 3 Run.( Pump 2 on stand By)
After cycle III the Cycle I will again restart. In any cycle if one of the Pumps fail or trip then the standby pump will come in Operation.
||PLC Logic for Cycle|Pump Operations||
The operation of Pump will be according to level. Let us take the height of wet well as 1000MM and Ultrasonic Sensor is there for level measurement , when the level reaches 50 MM Pump 1 will start and when level reaches 500MM Pump 2 will start , so the level will come down and when level again comes at 20MM the cycle will change and next cycle will Start and this process continues on.
PLC Inputs :-
Analog Input - 2001 Ultrasonic Sensor
0.0 - Pump 1 Trip
0.1 - Pump 2 Trip
0.3 - Pump 3 Trip
PLC Outputs :-
100.0 - Pump 1 Run
100.1 - Pump 2 Run
100.2 - Pump 3 Run

Troubleshooting with PLC Problems

Many a times it happens in the industry that a particular machine is not operating correctly or there is an error in some process. The reason can be numerous for these kind of problems like it is possible that some input is malfunctioning or processor of PLC is giving some problem. In this post we will discuss the general problems encountered.
||How to Troubleshoot PLC Related problems||
To check out the problems whether it is related to PLC for field devices , first of all connect to the the PLC and upload the PLC Program . Now every PLC Programming software have the feature to check the Error Log. Check out the Error Log in PLC and see if there are any errors.
There can be two types of Errors either Fatal or Non fatal , if there is Non-fatal error then simply clear it and if Fatal error is there then note down the code of error and check out the meaning of Error Code in the PLC user Manual.
The Fatal or Non Fatal errors can be easily monitored as every error has its unique code and necessary action can be taken to prevent the error.
The Fatal error is generally comes due to improper I/O allocation in PLC or Memory of the program is more than the PLC memory , due to battery , there can be various reasons , just check out the error code in manual and there you will also find the necessary steps to be taken to remove the error.
But sometimes it happens that a PLC Panel is installed in some machine and suddenly the machine stops to work and we also found that there is no problem in PLC. So in this case definitely there is some problem in the I/O connected with PLC. Yes we can identify that which input or output is malfunctioning.
Upload the PLC Program and monitor online and one by one check all the inputs and find that is there input is coming in PLC and similarly repeat this for the outputs. If some Input or Output device signal is not coming in PLC then definitely there is some problem in that , it can be due to wrong wiring or loose connections.
Also there can be situation that when all inputs and outputs devices signal are coming to PLC but still the machine is not operating , then it may be possible that Interlocking has been done in PLC , so in the PLC Program look out for the Interlock (IL) Instruction and check its condition and rectify the same.Subscribe to Automation-Talk by Email.

NV HMI RS232/RS422 Connection With Mitsubishi MELSEC-FX1N Series
NV HMI By Omron is also Capable of Communicating with Mitsubishi MELSEC-FX1N Series , MELSEC-FX2N/FX3U/FX3UC Series and MELSEC-Q Series. In our earlier Posts we saw the step by step procedure for Communication of NV HMI with Allen Bradley , Siemens S7-200 PLC and Modbus Communication of NV HMI.
||NV HMI Communication with Mitsubishi MELSEC-FX1N Series PLC ||
To connect the NV HMI with the Mitsubishi MELSEC-FX1N , it can be done in two ways either we can make connection via Tool Port(RS422) or through an Adapter.(RS232) Let us first see the How to Connect NV HMI with Mitsubishi FX1N through Tool Port.(RS485)
Mitsubishi PLC tool port--------------------------------------------------NV HMI
PIN 1 (-RD)---------------------------------------------------------------Terminal 5(-SD)
PIN 2 (+RD)---------------------------------------------------------------Terminal 4(+SD)
PIN 4 (-SD)---------------------------------------------------------------Terminal 7(-RD)
PIN 7 (+SD)---------------------------------------------------------------Terminal 6(+RD)
Note:- Short the Terminals 7 and 8 at the HMI Side.
Also the Connection of Mitsubishi FX1N PLC is also Possible using the RS232 via the Mitsubishi PLC Adapter with NV HMI. See the Below Connection Diagram.
Mitsubishi PLC Adapter<<---------------------------------------->> NV HMI
PIN 2 (RD)--------------------------------------------------------------Terminal 4(SD)
PIN 3 (SD)--------------------------------------------------------------Terminal 5(RD)
PIN 5 (SG)--------------------------------------------------------------Terminal 8(SG)
Note:- Also make sure to short the PIN 1 and 5 at the PLC adapter side.
After making the connections as stated above as per RS232 or RS485 we just have to make some settings in NV HMI software and PLC Programming Software.
||Settings in NV Designer for Communication With Mitsubishi FX1N PLC||
Open the NV Designer Software and Create a New Project and select the proper NV HMI Model which you are using and after that in PLC Type select "Mitsubishi MELSEC-FX Series" and then click Next and select System Memory Area accordingly. See the Below Picture for better Understanding.

Note:- Click on the Picture for a Better Clear View.
Now we have to define Communication Parameters Both at HMI and PLC side. To set the Communication Parameters in the NV Designer go to PT----NV Configuration and under Communication Parameter Tab select baud Rate as 9600Kbps , Data Bit as 7 , Stop Bit 1 and Parity as Even. See the below Picture for better Understanding.

Note:- Click on the Picture for a Better Clear View.
||Settings in Mitsubishi MELSEC-FX1N PLC || - Just make the D8120 as 0(The default value is 0, so normally nothing needs to be done.)
Now we have Done all the Necessary Settings Required for Communication of NV HMI with Mitsubishi MELSEC-FX1N PLC. Now You can make the HMI Screens as per yours Application and you will be able to access all the Bit Devices and Word Devices of the PLC.
If still you face any problem then you can write in Comment section. We will soon be posting for connection of NV HMI with other Mitsubishi PLC like MELSEC-FX2N/FX3U/FX3UC Series, MELSEC-Q Series and MELSEC-Q and A (CPU).

NV HMI RS232/Rs485 Connection With Siemens PLC S7200
NV Range of HMI by Omron can be Connected with Siemens PLC. NV HMI is available in three different Models. It is a compact HMI for Packaged PLC. In Our earlier posts we saw NV HMI Modbus Communication and NV HMI connection with Allen Bradley PLC. Today we will see as How to connect NV HMI with Siemens PLC.
How to Connect Siemens PLC with Omron NV HMI|NV HMI Communication with Siemens S7200 PLC
NV HMI communication with Siemens PLC is possible in two different ways i.e through RS232 and through RS485. We will see both the Communication Procedure here.
||RS232 Communication of Siemens PLC with Omron NV HMI||
For RS232 Communication first of all connect the S7-200 PC/PPI Cable and then make the Communication Cable as Shown Below.

PLC to GSM Modem Communication Cable Connection Diagram
In many Applications we required to Connect GSM Modem to PLC for Communication purpose. GSM Modems are Now a days becoming Very popular as they now come with RS232 Port and can be Communicated with PLC. Most of the General Purpose GSM Modems communicate with PLC with No Protocol Mode i.e we have to simple Send and receive Data through the RS232 port.
||Communication Cable Connection Diagram for Connecting GSM Modem to PLC
The Communication cable Required for Connecting the Modem with the PLC is same as a simple Cross RS232 cable but with a little Modification. Mostly all of the Modems Support the cable which we are going to make.
As there is RS232 Port at both the PLC and Modem Side, mostly is D-Type Male.
See the Below Picture for Connection Diagram for GSM MODEM Cable.

If you see properly then it is a simple cross RS232 cable the only thing which have to be done extra is that you have to short PIN 4 and PIN5 at PLC side and also shorting of PIN7 and PIN8 at the modem side.
Note :- We recommend to use a Shielded Cable for making this Communication cable and connect the shield to body of connector at one side.
