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 display panel. So to make this a 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.

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 servo drive model from the list and you can also set maximum rating of the drive through settings.



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.



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



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 same settings for every drive and you can save your project parameter wise, which saves your precious time.

If you have recently started learning PLC programming and has already understand the concept of choosing right type of PLC for any project, then it's now time to know about concept of Source and Sink in PLC. Understanding when PLC is connected as source and when as sink is very important for all the Automation engineers. Connecting a power supply to input or output of a PLC makes it input source or input sink and output source or output sink. So source and sink totally depends on how you connect your power supply.

Difference Between Source & Sink in PLC's


1. Sink Type: In a sink type, current always flow into the PLC and positive (+ve) of supply is connected to PLC input terminal (In case you are making your input as sink) and Negative (-ve) of supply is connected to common in Input module of PLC as shown below.

Remember the basic electrical theory, that current always flow from positive to negative. You can also memorize this by taking example of a water sink, where water flows to sink hole.

2. Source Type: In a source type, current always flow from PLC to external device such as switch or sensor as shown above. Here all the input of PLC are connected to negative (-ve) of supply and Common of Input module is connected to positive (+ve).

In the above image, we have taken example of Input side of PLC, here we have taken 2 PLC in source and sink configuration.

1. Here S0, S1, S2 are switches.

2. I0, I1, I2 are input's of PLC

3. "I" is the current and blue line is showing direction of current.

4. Positive (+ve) and negative (-ve) are terminal of power supply.


Note: Never confuse while connecting a NPN type PLC with NPN sensor or PNP PLC with PNP sensor.

The above explanation of Source and Sink was done considering Input side of PLC and same is true for output side of PLC. If you have any other question or query please feel free to leave your comments. If you like our article consider it sharing.

Cinterion MC52i terminal module is the advance version of MC52. The MC52i module handles all processing for audio, signal and data within the MC52i Terminal. Internal software runs the application interface and the whole GSM protocol stack. This is a dual band modem which can work on GSM 900/1800MHz frequency. This is a good MODEM which can also be used for sending SMS through SCADA system. This tutorial will guide you for making your own Power and Ignition cable for MC52i terminal, if original cable is destroyed or shorted. Subscribe to Automation-Talk by Email.

Jack of MC52i terminal is a female 6-pole Western plug which is used for power supply, ignition and power down. 1st pin of the jack is used for power supply and 8V to 30V can be applied on it. It is donated by PLUS (+). 2nd and 5th pin are free and 3rd is for sending power down signal. 4th is for providing ignition signal. 6th pin is used for ground signal and is denoted by GND. The pin arrangement is shown below.



To make your own cable you can simply use Pin 1 and Pin 6 with a 2 wire cable if you are not using other functions. When MC52i terminal is powered ON, the IGT_IN signal is activated automatically. After start-up, the MC52i terminal enters the net searching state. To turn off the MC52i Terminal use the AT^SMSO command, rather than disconnecting the mains adapter. This procedure lets the MC52i Terminal log off from the network and allows the software to enter a secure state and save data before disconnecting the power supply.

In some of the application in industries, need of increasing and decreasing the speed using VFD drive through a single control panel using the push of Buttons is required. One of the best example of such machine is sheet laminating machine where operator can simply increase/decrease the speed using buttons. In Omron JX drive this function can be performed with ease through parameter of the drive. Here we are not talking of MODBUS communication and will use input from terminal. This feature can also be done using MODBUS communication and also with the help of POT. Subscribe to Automation-Talk by Email.



Below are the important parameters which need to be set in Omron JX drive to use increasing and decreasing Speed feature using Buttons.

1. A001 : Frequency reference selection :

In this parameter select 02 to use Digital operator as the input source for frequency. By default this is set to 00 (Digital Operator- Freq. Adjuster).

2. A002 : Run Command Selection:

By default this is set to 02 for digital operator. Select 01 for terminal mode. By selecting this parameter, you will only able to give run command through control panel or terminal buttons.

3. C001 : Multi-function input 1 selection : UP

This is the parameter which lets you use first input button, say Start button as increase button. By default this parameter value is set to 00 for Forward (FW). Change this value to 27 which will increase the frequency.

4. C002 : Multi-function input 2 selection : DOWN

By default this parameter is set to 01 for reverse (REV) and we have to select 28 which will decrease the frequency. This feature is applicable while the machine is in RUN mode.

Notes the below points while using C001 and C002 parameters:

1. While the UP/DWN terminal is turned on, the acceleration/deceleration time depends on F002, F003/F202, and F203.
2. You can store a frequency set value after UP/DWN adjustment. Choose whether to store the value with C101.
3. Also, you can clear the stored frequency set value by allocating 29 (UDC) to the desired multifunction input and turning on/off the UDC terminal.
4. The UP/DOWN function is disabled when the JG operation is enabled.
5. The UP/DOWN function is enabled when the frequency reference selection (A001) is set to the Digital Operator (02).
6. The UP/DOWN function is enabled when the multi-step speed reference is enabled.

After setting the above parameter you can test this by using Start and Stop buttons. Use start button for increase and stop button for decrease. Now press and hold the increase button to increase the speed and release the button to hold the speed to that point and do same for decreasing the speed. If you have any issue in setting your button to UP and down mode (increase/decrease) then please let us know. To get the latest tutorial and program subscribe to Automation-Talk by Email.
