Reading SDO parameters for Open From PLC project
Video Tutorial
Using the “Open From PLC” option to read the XG-PM project will include all servos connected to the XBF-PN04B or XBF-PN08B module.
-
XG-PM can use the Online menuè EtherCAT Slaveè Autoconnect procedure to read the node numbers from the servo drives and automatically associate those node numbers with the Axis number.
-
Node number X will be Axis X so Node number 1 will be Axis 1.
-
Axis number will be assigned to the order the drives are connected.
-
XBF-PN04B supports node numbers 1 ~ 4 for servo drives.
-
XBF-PN08B supports node numbers 1 ~ 8 for servo drives.
| Step | Action |
|---|---|
| 1 |
Connect the XG-PM project to the XEM CPU. Click on the XBF-PN0xB module to highlight it. This example shows XBF-PN08B.
|
| 2 |
Select Online menu è EtherCAT Slave è Autoconnect.
|
| 3 |
Select the check box next to Includes SDO (Servo) parameter read. This will read the servo drive parameters including the drive’s node number. Press OK when done.
|
| 4 |
Press OK on message showing successful connection.
|
| 5 |
Open the SDO parameter files to check Node ID.
|
| 6 |
Index 2003:00 for the iX7NH servo drive will be the node number. This example shows Node 1 being read in the SDO parameter file.
|
| 7 |
Make sure Slave Number matches the Axis number for your application.
|
| 8 |
If information is correct, then Save the project and perform a Write Project to XEM CPU. If the information is wrong, proceed to Manually Associating Servo Drive with an Axis Number. |
