Motion Controller, 2-axis Universal Driver, Ethernet, Basic GPIO and PCO

The web interface allows a quick configuration of the XPS-RLD, as simple as that in the ESP301 controller.

The system files stored in the XPS-RLD are easily accessible, much like a Windows environment. At the same time, these files can be edited and saved in situ, without having to pull them from the folders and opening them with notepad or other text editor.

Moving away from numerical error codes, a new set of more descriptive error codes is now available and visible in the XPS-RLD.

The XPS incorporates pre-configured motion groups and user-definable motion groups to optimize the performance and simplify the use of advanced features like line-arc trajectories, splines, contouring, and complex PVT trajectories. These motion groups can be single axis positioners, spindles, gantry groups, XY groups, XYZ groups or multiple axis groups. The flexibility of grouping stages greatly improves process flow and error handling and provides a uniform structure for easy application development.

An extensive set of compensation features are available to the user including backlash, linear error and error mapping in single, 2D or 3D. All compensations are corrected dynamically at each servo cycle, updated at the rate of 10 kHz. This broad selection of options transforms the most basic positioner into a high performance device, thus increasing the accuracy and performance of any motion application, culminating in more reliable results.

The Line-arc trajectory is a motion path defined by a combination of straight and curved segments (available only for positioners in XY groups) such that constant speed is maintained throughout the entire region of interest. Sequential execution of the lines-arc trajectories eliminates discontinuities. A dedicated function performs a precheck of the trajectory to ensure optimized and safe execution within the positioners' parameters. The spline trajectory executes a Catmull-Rom spline on an XYZ group, passing through user-specified points with 3rd order polynomial segments at a constant speed. Similar to Line-arc trajectory, spline trajectory has functions for trajectory prechecking. The PVT-mode is the most flexible mode for creating complex trajectories. In PVT, a trajectory element is defined by the end position (P) and end speed (V) of each positioner plus the duration for the element (T). The controller then calculates the cubic function trajectory that will pass through all defined positions at the defined times and velocities. PVT is a powerful tool for any kind of trajectory with varying speeds and for trajectories with nonlinear motion devices.
