How to Change Servo Drive Parameter using Omron CX Drive

In industrial automation, we install and program many servo motors and drive in industries every day and so sometimes it becomes very problematic to set each and every drive with the display panel. So to make this an easy process, you can also use servo drive software to make changes or set new parameters through your laptops. Today let me tell you about CX drive, which is Omron product and by which you can program your drive without touching display panel. Almost all the automation product manufacturing company provide servo drive software so you can check with your drive provider. Subscribe to Automation-Talk by Email.


Required Conditions

1. You must have CX-Drive installed on your laptops/desktops.

2. Servo drive should be connected to set or change parameter's online.


In this example we have selected R88D servo drive.


Recommended Reading: How to Reduce Electro-Magnetic Interference in Servo Drives

Steps to Change Servo Drive Parameter Using Omron CX Drive

1. Start CX Drive software in your laptop. If you have installed CX-One software and all its component, then it will be under Omron -- CX-One -- CX-Drive

2. Now click on new and make your servo drive project. Here you will have to select a servo drive model from the list and you can also set the maximum rating of the drive through settings.

CX drive new project

3. Now expand your new project and click on Parameter Editor. In parameter editor, you can even choose from different parameter list like basic parameters, gain parameters, vibration suppression parameter, analog control, special setting parameter etc.

CX drive parameters

4. Suppose we first want to set basic parameters, then just click on it and you will be shown all the basic parameters of the servo drive.

Now suppose we want to change control mode of the drive, then we can use parameter Pn001 and can set its value as required for the project. See the example below.

CX drive parameters pn001

Similarly, you can change any parameter of servo easily.

Now to transfer this new setting to your drive, just go to transfer, which is under drive tab and transfer the settings to your drive. And if you are not connected to your drive you can also save your setting for after use. I like this method because you can use the same settings for every drive and you can save your project parameter wise, which saves your precious time.

How To Find PPR and Maximum Frequency of Encoder

Encoder comes with a specified PPR i.e pulse per Revolution and Maximum Frequency output of the pulses given by encoder. Generally, encoders are mounted on the shaft of the conveyor, so according to the resulting RPM we should select the encoder with a proper PPR and output frequency.


How To Find PPR and Maximum Frequency of Encoder


How to Find PPR and Maximum Frequency of Encoder



The encoder is interfaced with the PLC for counting the pulses given by encoder and taking the feedback. PLC inputs also have a frequency range for the pulses which it can accept. So calculating the frequency of pulses by the encoder is important in an application. Below is the formula to find the Max. The frequency of encoder in from the PPR and RPM.

Max. Frequency of encoder in Hz = (RPM / 60) * PPR

So if the encoder is mounted where the RPM = 2000 and PPR of the encoder is 360 the frequency of encoder will be 12KhZ. So we could find out that our PLC will be able to count pulses with this frequency or not.


Recommended Article: Using High Speed Counter in Omron PLC


Let us also see the difference between Single turn and Multi-Turn encoders.

In single turn Encoder, the output code is repeated after every single revolution of the encoder shaft i.e we can not actually determine how many turns have encoder made 1 or 1000.


In Multi-turn Absolute encoders, the output is unique for each revolution or for every shaft positions up to 4096 revolutions and we can get to know that the numbers of rotation of Encoder.

How to Save Energy using VFD/Inverter/AC Drive

Variable Frequency Drive or VFD is a power electronics device which has revolutionized the Electrical Industry. VFD have made possible the speed and frequency control of the AC Motor. VFD gives a load of other advantages other than speed control. VFD is the best starting method for AC Motor. Also, the energy saving feature in drive makes an added advantage for saving the electricity and thus reducing the cost.


How to Save Energy


Save Energy by Using Baldor VFD


Baldor VS1MD series VFD have a special feature through which we can save energy and thus reduce the cost of electricity bills. In almost all the industries where there are many motors, most of the electricity bill is raised from current consumption by these motors. But by installing Baldor VFD we can get up to 30% energy savings and thus the cost of the drive can be recovered in just 1 Year.

All the drives have PWM output, so it means that even if we don’t set the parameter we will get the energy savings and that is for sure. If we compare two motors of same ratings, for example, there are two motors of 10 HP Motor A and Motor B. Motor A is run through Star Delta Starter and Motor B is through VFD.

Both the Motors A and B are used in the same application with the same load condition and the same environment. If we install an Electric Meter and monitor the Units consumption then we will find that there will be around 20 to 30% lesser electric units consumed by Motor B which is run through VFD.


Parameter Setting in Baldor VFD for Energy Savings


To boost the energy savings in Baldor VFD, there is one Parameter. Parameter Number F40, in this put the value in between 0 to 30. It adjusts the output voltage according to the load status. It is set as a percent of a maximum output voltage.

When there is any pump or fan application, setting this parameter can dramatically reduce energy consumption by decreasing the output voltage with light loads or load behavior.

We will be discussing more about VFD Application and its advantages, so till then subscribe to Automation-Talk by Email, so that you can get all the latest updates.

Understanding Torque and Its Simplest Explanation

In the past few topics of AC Motor basics we have seen about general motor terms, different types of motor load and the Calculation of Synchronous speed from Poles. We all frequently use term called Torque in our day to day work life. But, do we really know the actual meaning of "Torque". We got many request from our readers to explain the term torque in simple words. So get a cup of coffee and sit back. Subscribe to Automation-Talk by Email.


Understanding Torque and Its Simplest Explanation


What does Torque Signify?


In our industrial applications when we have to select the driving motor for any load we are always concerned about the horsepower, but believe me the real driving force is TORQUE and not horsepower. In the simplest word torque is the twisting/rotational force exerted by the drive on the load. Now let us take a simple example.

Do you remember that sometimes you try to open the lid or open a bottle but after so many tries it does not open? Do you know the reason why it doesn't open? Because we are unable to supply or apply the adequate torque to open the lid. The solution for this can be a) grit our teeth and try harder, b) use a rubber pad, or cloth, to increase the ability to transmit torque without slippage, or c) use a mechanical device to help multiply our torque producing capability. If still, it doesn't open then give it to some stronger person!!

Well, the main motive behind the above example was just to make u feel something about torque. We are always confused among HP and Torque. Now let us suppose that after so much try also the lid did not open and now we will wrap a cord around the lid and supply a force to the end of the cord through a scale. See the below diagram.




Example for Torque Calculation


Can we tell the torque required in this case? Yes, we can, the torque requirement will be the force as depicted on scale multiplied by the radius of the lid. For example, if the reading of force on the scale is 17 lbs( at the time of breakaway of lid) and the radius is 3 inches then the torque requirement would be:-

T = F * R = 17 * 3 = 51 lb.inches


Simplest Explanation of Torque


However, the above example gives a clear illustration of the torque but lets us discuss one more thing which is observed in industrial applications. If we recall the above example then we can derive one more term called "Stiction". Stiction can be defined as the amount of torque required to make a load lose and start the first revolution. Stiction is nothing but only the second name of the breakaway torque and frankly speaking for every industrial application the breakaway torque requirement of any load is greater than the continuous torque requirement for running the machine.


The amount of "stiction" present in a machine will be dependent on the characteristics of the machine as well as the type of bearings that are used on the moving parts. Below you can see a picture in which the breakaway torque requirement of different machines is shown.



So, we have got now a clear view of the torque and its characteristics, in the next few days we will try to see more different types of torques and detailed explanation of torque in a simple way. Till then you can subscribe to get all latest updates via Email.

Advantages/Benefits of Servo Motor Over Induction Motor

We have discussed about the servo basics and servo control terminology in the previous article. We have studied about the different components of a servo control. Today in this post we will see that what are the advantages that we get by using the servo motor over the AC Induction motor. This article is in continuation to the previous one and here we will learn more about servo control.



Advantages and Benefits of Servo Motor Over Induction Motor


Servo Motor V/S AC Induction Motor



Let us, first of all, see that what are the advantages of using the servo motor. Why it is that Servo Motor gives better efficiency for many applications. Suppose that an Induction motor is connected to run a grinder at full speed, we can expect to get some level of performance in this case. But is same grinder is run through Servo Motor we will get the next level of performance. So how it is achieved? Let us discuss in detail.

As we have discussed in the previous post that a servo motor is always used with a control and feedback device. The servo control issues the command for the position and the feedback device monitors the load and inform the servo control so that the control can correct the position if there is any error.


Advantages of Servo Motor Over Induction Motor



1. Increased Performance:- A servo motor has got more acceleration rate and higher speed capabilities compared to the induction motor and thus allowing the enhancing the production rate of the machine.

2. Smaller Size:- Servo motor has the higher output torque rating for the same size of the rotor. Thus Servo motor can be installed in a place where space is of prime concern.

3. Less Weight:- Weight of the Induction Motor is more than the servo motor for the same rating.

4. Highly Efficient:- A servo motor is designed in such a way to have peak efficiency and thus a better power conversion factor and thus saving the power.

5. Quick Positioning:- Servo motor can be issued a command to move accurately to the desired position in very less time, this is not possible with Induction motor.

6. High Degree of Accuracy:- In critical applications where we need the accuracy in microns or mm, the servo motor can provide it as it is designed for highly precise positioning.

7. Control-ability:- Last but not the least, as the servo control is used along with the servo motor thus a full control is achieved over the servo motor.

Also, one major point to be noted here is that the power of servo motor is utilized only when a position move command is issued to servo motor and rest of the times servo motor is normally turned off, thus a large amount of power is saved.

We hope that after reading this article about the advantages of servo motors over induction motor, we have come one step ahead. In the next article, we will discuss about the Permanent magnet DC Motor and AC Brushless Motor, till then you can subscribe to Automation-Talk by Email to get all latest updates.

Test Procedure of AC Induction Motor

AC Induction Motors are the heart in any type of Industries, for any work you require Motor to do the work. Hence there must not be any issue in calling "AC Motors" as the heart for Industrial applications. Specification of AC Motor includes its Capacity i.e Rating of the Motor, its Frame Size, Rated Voltage and Current, Frequency and its scale of Insulation. But, how many of us knows the testing of AC Motor? Don't worry we will see here the detailed procedure to test the AC Induction Motor


Test Procedure of AC Induction Motor

How to Test the AC Induction Motor


As we buy the AC Induction Motor from the market, it has been tested previously at the manufacturing time for all the defects, But still, we should also know and understand the testing procedure of AC Induction Motor. We will see step by step testing procedure here for AC Motor.

Magering:- Mager is used to test the Insulation of the Motor. But what is Mager??

Mager is actually a small DC Generator rotated by hand, it generates High Voltage and less Current. For the testing purpose,
upto 2000V it is hand operated and above 2000V it is mechanically operated.

The resulting outcome equation is as:- 1mohm / KV and 0.44mohm / 440V.

Drop Test:- Drop test is used to check the resistance of individual winding, and they should be equal for a more efficient AC Motor.

<> Absorption Coefficient Test:- It is same as Magering procedure. In this test procedure of AC Induction Motor, Insulation value is measured for two different time duration one for t=15 sec and other for t=60sec.

If Insulation Value for t=15 sec is less than 1 then AC Motor OK.
If Insulation Value for t=15 sec is greater than 1 then AC Motor NOT OK.

So It may be possible that moisture is present in the Windings of AC Induction Motor, To remove the Moisture from the Motor Windings, Raise the temperature of motor windings gradually so that all the moisture evaporates out. But one point to keep in Mind is that the rate of change of temperature of Motor Windings should not be greater 1 deg. celcius per 30 minutes.

After removing the moisture from the motor windings again perform the Absorption Coefficient Test and if this time Insulation Value for t=60sec is less than 1 then AC Motor OK. If you like this article, please Subscribe to Automation-Talk by Email and share this article with your friends.
