EtherCAT^® for ultra precise motion control

The LS Electric XGB series controllers are motion control powerhouses. These PLCs provide numerous motion control capabilities using the integrated motion inputs/outputs, high-speed counter modules, or EtherCAT communication modules. With LS XGB PLC's advanced motion you get:

• Precision moves that can be executed from the position table or within the program code
• Various single-axis operations: position control, speed control, feed control, multi-axis simultaneous start, and point operation
• Various multi-axis operations: circular arc interpolation, linear interpolation, helical interpolation, ellipse interpolation
• Single-axis torque control supported with EtherCAT (XBF-PN0xB) modules
• Switching control during operation: position/speed control switching, speed/position control switching, position/torque control switching
• CAM control: 8 types
• Seven homing methods: in positioning control, use Homing method supported by each servo driver (17 types); set the origin of machine without homing by setting the floating origin
• Acceleration/deceleration methods of Trapezoid or S-type
• High-speed start process: 1ms (1~2 axes), 2ms (3~5 axes), 3ms (6 axes); no delay time between axes in simultaneous start and interpolation start

With EtherCAT modules installed, you can add up to 16 axes of EtherCAT controlled motion to your XGB PLC. EtherCAT provides real-time, deterministic communication with multiple nodes for high precision motion, along with these other advantages:

• Less wiring for complex motion applications, send signals over network instead of hardwired
• Extremely fast cycle times
• Multiple topologies can be used
• Built in redundancy - network can detect a break
• CANopen over EtherCAT (CoE) device profiles allow easy addition of 3rd party devices

Motion configuration software for accurate positioning

XG-PM software is provided free of charge in the same download as the XG5000 programming software. This software provides table-based position configurations of up to 400 moves per axis and a run command tool for easy position testing. The XG-PM software also has a System View feature that allows all 6 axes to be seen at once and any modifications needed to the motion profiles can be made without touching the user program.

To aid with validation, convenient 2D dimensional trend graphs of position configurations are provided and the XG-PM software utilizes an intuitive error code system for easy troubleshooting.
