Communication Instructions

PDO data description

PDO realizes the periodic data exchange between the master station and the slave station. The PDO mapping object can add or reduce mapping parameters through the master station (the maximum number of mapping variables for TPDO and RPDO is 10 respectively). The default mapping of PDO mainly includes the following:
Inverter control command, target frequency given.
The current status and running frequency of the inverter can be read in real time.

Mailbox data SDO

Mailbox data SDO is used to transmit non periodic data, such as the configuration of communication parameters, the configuration of inverter operation parameters, etc. Types of CoE services include:

1. Emergency
2. SDO request
3. SDO response
4. TPDO
5. RPDO
6. SDO information, etc

Operation Example

Controlling VF-101 inverter with Beckhoff controller

The following describes how to use the EtherCAT communication card via TwinCAT3 simple configuration.

Note: Regarding the network card, please choose to use Intel Chip 100M Ethernet card.

1. Install TwinCAT3

2. Add xml file
   Copy the xml configuration file (VF101_ECAT1_T0_00010_00000_M_20221220.xml) of VF101ECCT1 to the following directory:
   TwinCAT3 directory: TwinCAT\3.1\Config\Io\EtherCAT.

3. New project
   a. Open TwinCAT3, open the new project box through the path “File->New->Project”, and click OK to create a new TwinCAT project.

b. Install the TwinCAT network card driver: Click the drop-down menu “Show Real Time Ethernet Compatible Devices…”, the following dialog box will pop up, select the local website in the “Incompatible devices” column, click Install, after completion, it will be displayed in “Installed and ready to use devices” “The installed network card appears in the column.

c. Search device: Right click Devices in the I/O drop-down box on the left column, and select scan. After confirmation, wait for a moment to pop up the “Device has been found” window. Follow the figure below for a series of confirmation operations. Finally, you can judge whether the device has successfully established a connection with the master station through the state status in the Online tab.

4. SDO data list
   After entering the OP state, the user can observe the data through the SDO data list, or modify the SDO data by double clicking the object dictionary.

5. Configure PDO parameters
   a. Configure RPDO: The extension card can choose 4 RPDO channels, numbered 0x16000x1603, each channel can support up to 10 RPDO mappings, the user can add the required mappings according to the needs; the first two mappings of each channel have default configuration, which can be reconfigured by the user.

b. Configure TPDO: The extension card can choose 4 TPDO channels, numbered 0x1A000x1A03, each channel can support up to 10 RPDO mappings, the user can add the required mappings according to the needs; the first two mappings of each channel have default configuration, which can be reconfigured by the user.

6. Reactivate the configuration and switch to run mode
   After each change of the PDO mapping, the user needs to reactivate the configuration for the new configuration to take effect.

7. Control the inverter through PDO
   Set the value of the corresponding PDO map to control the operation of the frequency inverter.
   Note : The given source of some function codes needs to be set to TwinCAT first to be valid when the function code is changed in TwinCAT;
   For example, for the function code 0x3101 cmd, it is necessary to set the function code F01.01 to 3 (the given source is set to an optional card), and then change the value of 0x3101 cmd in TwinCAT, so that the inverter can be controlled.

Use OMRON controller to control VF101 inverter

The following introduces the operation steps of running the VF101 inverter through the simple configuration of OMRON’s NJ501-1300 master station.

1. Install Sysmac Studio

2. Configure the master IP address.

3. New project
   When creating a project, select the correct device model.

4. Communication configuration
   a. After entering the main interface, open the communication settings dialog box through the path “Controller- >Communication Settings”, select “Ethernet- Hub Connection” for the connection type, and set the remote IP address to “192.168.250.1”.

b. Click “Ethernet Communication Test”, if the test is successful, you can go to the next step.

c. Import the xml configuration file
Double-click “EtherCAT” in the “Configuration and Settings” drop-down box in the left column, then right-click “Main Device” in the middle column, click “Show ESI Library”, click “Installation File”, find the path where the user- specified xml file is located and Open, click OK and the xml can be installed successfully.
This document takes importing the VF101_ECAT1_T0_00010_00000_M_20221220.xml file as an example. After the import is successful, the xml file name will be displayed in the Omron software directory.

5. Scan the device
   Click “Online”, then click “Compare and Merge with Physical Network Configuration”, select “Apply” and close it. At this time, it can be observed from the lower right corner that the controller status is online.

6. Parameter configuration
   Click “Offline” to open the I/O mapping on the left column, and you can see the mapping variables configured by default in the system. Users can set relevant variables according to their needs.

7. Edit PLC program
   a. a.Define and add variables: You can set the variable name of the PDO mapping, and add new variables

b. Write PLC program.

c. Add the program to the main task through the “Task Settings” window.

8. Download to the controller: After running online, click “to the controller” to observe the execution of the program in real time.
