What is Servo, servomotors and example of applications
What is Servo, servomotors and example of applications
What is servo?
Servo is the systems where the feedback or error-correction signals help control mechanical position, speed or other parameters. The function of the servo is to receive a control signal That represents a Desired position of the servo output shaft, and apply power to its DC motor until its shaft turns to That position. It uses the position-sensing device to determine the rotational position of the shaft, so it knows the which way the motor must turn to move the shaft to the commanded position. The shaft does not rotate Freely typically round and round like a DC motor, but rather can only turn 300 degrees for example.We Often use servodrive to control servomotor
What is servodrive?
In typical applications the servo drive receives a command signal from a control system devices,
amplifies the signal, and sends electric current to a servo motor in order to Produce motion proportional to the command signal. Typically the command signal represents a Desired position, torque or speed. A sensor is the which is attached to the servo motor the motor's actual reports status back to the servo drive. The servo drive then compares the actual motor status with the commanded motor status. It then alters to correct for any deviation from the commanded state.
Where We Can use Servos?
Two examples based on Parker Servo Products:
1. Rotary Indexer
Description: An engineer for a pharmaceutical company is designing a machine to fill vials and wants to replace an old style of the Geneva mechanism. A micro-stepping motor motion and smooth Will Provide Will Prevent spillage. The indexing wheel is aluminum and is 0250-inch thick and 7.5 "in diameter. Solving the equation for the inertia of a solid cylinder That indicates the wheel has 119.3 oz-in2. The holes in the indexing wheel Reduced the inertia to 94 oz-in2. The vials have negligible mass and may be ignored for the purposes of motor sizing. The table holds 12 vials (30 ° apart) That must index in 0.5 seconds and dwell for one second. Acceleration torque is calculated to be 8.2 oz-in at 1:33 rps2. A triangular move profile Will result in a maximum velocity of 0:33 rps. The actual torque requirement is less than 100 oz-in. However, a low load-to-rotor inertia ratio was Necessary to Gently move the vials and fill Them
Product Solutions from Parker:
Drive Indexer Indexer * SX Drive Motor S83-135
* The 6200, AT6200, and Model 500 are other
That indexer products have been used in these
types of applications.
2. Labelling Machine using the linear solution 
Description: Bottles on a conveyor is run through a labeling mechanism APPLIES That a label to the bottle. The spacing of the bottles on the conveyor is not regulated and the conveyor can slow down, speed up, or stop at any time.
Machine Requirements:
• Accurately apply labels to bottles in motion
• Allow for variable speed conveyor
• Allow for Inconsistent distance the between bottles
• Pull the label web through the dispenser
• Smooth, consistent labeling at all speed
Solution:
A That motion controller can accept input from an encoder mounted to the conveyor and reference all of the speeds and distances of the label roll to the encoder is required for this application. A servo system is also required to Provide the torque and speed to Overcome the friction of the dispensing head and the inertia of the large roll of labels. A photosensor connected to a programmable input on the controller monitors the bottles' positions on the conveyor. The controller commands the motor to Accelerate labels to line speed by the time the first edge of the label contacts the bottle. The label motor moves at line speed until the complete label is applied, and thendecelerates to a stop and waits for the next bottle.

How to scale the analog inputs and outputs - PLC scaling examples
How to scale the analog inputs and outputs - PLC scaling examples
Analog I / O whether it is 4-20mA or 0-10 V are connected to pressure transducers, level probes and other analog devices. As the PLC programmer or engineer control Will you need to get some knowledge about scaling plc analog signals from the I / O modules. Scaling helps to convert the analog value to measure units (pressure, level etc..).
Most industrial applications usually require measurements in engineering units, the which Provide more meaningful data. We can achive this by using the conversion formula shown: Example by AutomationEngineering.
Time for example
If We Want to measure levels in tanks from 0 to 65 meters then our L = 0, H = 65 max value from our analog cards 32 000 (in engineering units). A current value from the analog inputs is 13 454. Now if We calculate it using equation We Will get our current level of 23.7 meters.
Looks slightly different situation now with Analog Output.
Your PLC program has to calculate the digital value to send to the analog I / O module. There are many Airways to do this, but most industrial applications, are understood more easily if you use measurements in engineering units. We can do this by using the conversion formula shown.
Consider the following example with the level of measurement
We know there is 38 meters of liquid in tank. Our H = 65m L = 0m. Max analog output value is 32000. We use our calculation if We Will get 18 707 the which We Are going to send to our Analog Output.Programmable Logic Controllers have many ready to use the instruction for scaling.
Siemens S7-200 PLC scaling of the analog input to the output data format REAL (S_ITR)
The S_ITR function permits you to convert the analog input signal into a normalized value of the between 0.0 and 1.0 (type REAL)
The following table explains the abbreviations used:
| Parameter | Description |
| Ov | Scaled output value (output value) |
| Iv | Analog input value (Input value) |
| Osh | Upper scale limit for the scaled output value (Output scale high) |
| OSL | Lower scale limit for the scaled output value (Output scale low) |
| Ish | Upper scale limit for the scaled input value (Input scale high) |
| Isl | Lower scale limit for the scaled input value (Input scale low) |
Learning Wonderware Intouch HMI Modbus for connection
Some days I again dabbled Wonderware Intouch HMI to display animated data & data2 modbus. Since I do not have a hardware PLC / equipment that can transmit data to the serial port modbus laptop, I am finally using modbus RTU emulator . Then, since I only have one laptop, then to transmit serial data from the RTU emulator to use InTouch virtual serial port emulator . These are obviously pretty good tool to learn modbus connection to the HMI without real hardware ... thanks to the great developers.
The following image is a comparison with simulated HMI and RTU modbus emulator via virtual serial ports, a hardware configuration of the HMI with modbus RTU via cable.
Ok, so to start learning this, we do the following STEP 2:
I. Preparation Software
Prepare and install software2 follows:
- Wonderware Intouch 10 (can be from the office .. hehe. but the demo version can also be obtained from Wonderware representative in Jakarta. Look at his blog mas Handy about how to order it)
- Wonderware Factory Suite I / O Common Component (installed from a CD Device Integration)
- Modicon MODBUS Serial IO Server (installed from a CD Device Integration, after installing the Factory Suite I / O Common Component)
- virtual serial port emulator (output Eterlogic, freeware)
- modbus RTU emulator (made by mas Rifqi Imanto, salute such tools Cool ..). In addition to these tools, we can also use other emulators, such as PLC modbus simulator artificial Conrad Braam.
II. Run Virtual Serial Port Emulator
Click the shortcut on the desktop and windows display appears as follows:
Configure the menu: Device -> create, select the type: pair
Select the virtual port (in this example is COM3 and COM4), then Finish
Henceforth we will use the port for connection to COM3 and COM4 Intouch HMI Modbus RTU for connection to the emulator.
Run TSB virtual ports, and minimize:
III. Configuring the Server IO
Go to Start -> All Programs -> Wonderware Factory Suite -> IO Servers -> Modicon Modbus
And the display will appear as follows:
Configure the COM port by the way, select: Configure -> Com port settings
Fill in the configuration as follows, in this case we are using COM3 which is a virtual serial port such as a pre-configured. Press done when complete.
Configuring a new Topic, select: Configure -> Topic definition
Nama2 topic list appears, select: New
Configure the following topic:
Topic Name: fill in whatever name (in this example: testmodbus)
ComPort: select the serial port where the tool is installed (in this case virtual serial port COM3)
Slave Device Type: 584/984 for addressing five digits, 484 for 4-digit address, and E model PLC untu 6 Digit Addressing (in this example, because the emulator uses modbus RTU addressing five digits, then the slave device type is selected who is 584/984 )
Once completed, then a new topic (topicmodbus) will appear in the list topic.
Let the software IO server to remain open, or diminimize.
IV. Configure Intouch
Go to Start -> All Programs -> Wonderware -> Intouch
Intouch Application Manager display appears, select: File -> New
Follow the instructions on the wizard, to create a new application, call by name testmodbus
Double click on the application testmodbus, so the display appears Intouch - WindowMaker. This view is used to create images and animations.
Well then we need to configure this InTouch to communicate with modbus via IO Configure the server that we already had. Remember earlier we have made the topic? Now we will create an access name corresponding to the last topic.
Open the menu: Special -> Access Names
Access Names will appear. Create a new Access Names by choosing the Add button
Add Access Name display appears. Remember earlier we have made the topic "topicmodbus" on the IO server configuration? Now fill in the topic name them, and for the Application Name field, fill: MODBUS. Then select OK.
Access topicmodbus name was added to the list
Next we need to create a tagname. Tagname is the definition of variable names associated with modbus address or I / O from device. For that tag is also associated with an access name that you created earlier.
For that, select: Special -> tagname Dictionary
Display appears tagname dictionary,
Select: New
Fill tagname: for example, tagmodbus1
Select Type: I / O discrete (because the data is discrete modbusnya)
Select accessname: topicmodbus (in accordance with an access name that you created earlier)
Item contents: for example, 40 001 (modbus address which we will read / display)
Well, after configure access names and tagname, then we proceed next to a picture-drawing and animation
Still in Intouch-WindowMaker, select menu: File -> New
Properties window is displayed, fill in names: for example, testmodbus
Blank windows appear with the name testmodbus, create an image circle for example.
Create animations for the circle. Kira2 this scenario, if the modbus data on 40 001, then the color of the circle becomes green, if the data modbus 40 001 off, then the color turns to red circles. Double click the circle, the display appears as follows:
Choose: Fill Color -> Discrete
Display appears as follows, in a column expression, tagname content we've created earlier, namely: tagmodbus1
Once ok, then select File -> Save Window, and the animation is ready to run
V. Prepare Modbus RTU Emulator
Open modbus RTU simulator
Remember we will be using virtual serial COM4 to connect to the RTU emulator (when we Configure virtual serial port emulator software). Create RTU register, select the port: COM4, and select the button: open the port.
RTU emulator up and running!
VI. Animation in Intouch
At Intouch, WindowMaker, select the runtime on the top right corner.
Will appear, Intouch - WindowViewer
At first the image circle is red, because the initial 40 001 modbus data is 0 (off).
We try to change the data modbus 40 001 to 1 (on) on modbus RTU emulator
So in the view-WindowViewer Intouch, the circle turns into green (on)
Well, we managed to animate Intouch HMI to read modbus data. Then we can try with images and animations are more complex.
This application can also be used at the time of acceptance test (FAT / SAT) on the HMI installation project in the industry.
Good luck ...
