L7 General Purpose AC Servo System
The L7 general-purpose AC servo system is the result of sixteen years of research and development and seven generations of upgrades by Leadshine Intelligent. It includes three communication types: EtherCAT bus, RS485, and pulse.
Since its launch, the L7 series has been widely used and highly praised in automation equipment in industries such as electronics manufacturing, lasers, engraving, injection molding robots, machine tools, logistics, textiles, medical, and new energy, thanks to its high performance, high quality, high stability, and ease of use.
To help you easily connect and debug your L7EC series PLCs with mainstream PLC master stations such as Omron, Keyence, Beckhoff, and Leadshine, we will be providing a series of training sessions. This session will introduce the key connection steps with a Keyence PLC master station:
Part 01
New project, improve PLC configuration
Open the software, create a new project, and select the corresponding PLC version.
In the "Confirm Unit Configuration Settings" dialog box, select "Yes" to configure the PLC. Choose the power supply unit and motion unit according to the actual PLC configuration. Open the communication settings, select Ethernet, enter the PLC's IP address, and perform a connection test. After the test is successful, click "OK" to establish the connection between the software and the PLC.
Click "PLC Transfer" to send the newly created project to the PLC.
Part 02
Import ESI files and configure PDO and axis parameters.
Click on Axis Configuration Settings to configure the axes. When using the Leadshine L7EC servo for the first time, you need to import the ESI file. Click on ESI File Registration and find the corresponding ESI file.
Select the corresponding driver, and then configure the PDO: On the slave detailed settings page, click PDO mapping, click "Add" → the "PDO Add" interface will pop up, select the first group of PDO parameters "1600 Receive PDO 1" from the drop-down menu → click "OK". Similarly, add TxPDOs in the same way. To add or remove PDOs, double-click "Receive PDO 1 (0x1600)" in the "PDO Mapping" interface to enter the "PDO Edit" interface, and click the "+" button to add a PDO or the "×" button to remove a PDO.
After configuring the PDO mapping, click on Motion Function Settings to map each configured PDO to its corresponding motion function. Once configured, enter the encoder resolution as needed. Then, perform coordinate transformation calculations as required.
Click "PLC Transfer" to send the corresponding configuration to the PLC, thus enabling communication between the PLC and the driver.
Part 03
Simple run test
Select monitor mode, right-click the motion control module, select "trial run", the trial run page will pop up, click Forced Action Enable Deactivation and Forced Servo ON, then press and hold JOG in the positive or negative direction, the motor can rotate forward or reverse.
That concludes this video segment. Stay tuned for more great video tutorials.
