Software for servo-presses.

Baumüller is introducing an update for the current complete software package for the control of servo presses on the market with their Motion-Axis Servo Press software template. The company offers a complete system for servo presses consisting of the engineering, hardware, and software. The Motion-Axis Servo Press software template has now been updated and the new version offers numerous new functions.

The existing version of the software template could already be used to couple multiple motors in a synchronous position. Intelligent energy management was also already included in the package. A new feature is the automatic alignment of the system boundaries when creating this curve. This function enables the machine's performance and productivity to be increased. An interface for communication with the higher-level control is also now a standard feature in the new version.

New version: Machine template for control, visualization and drives.
Baumüller's software templates save developers a lot of time: The templates already include a large number of the required functions. In addition to motion modules, the package also includes templates for functions such as curve generator for press movement or a prepared used interface. These therefore do not have to be set up by the developer for a new project, but instead only have to be selected and parameterized at the start. Routine tasks, such as instancing modules or linking variables to the modules, are no longer necessary. The machine programmer no longer has to worry about the basics in the development, but can use the time saved entirely for process programming instead.

With the Motion-Axis Servo Press software template, especially for servo eccentric presses, the company is now publishing an update of its tried and tested servo press templates with further performance improvements. Other kinematics can be implemented on request.

For maximum speed: Intelligent curve generator.
With the intelligent curve generator, the user can either freely enter their press profile or use various predefined curves. In case of manual input, the customer can choose whether to enter the data points linearly (ram) or as an angle (crank shaft). To achieve a highly flexible movement sequence, profiles with up to 20 interpolation points (data points) can be designed. Further, not only standard curves, but also the user's own curves (recipes) can be loaded and further processed. In addition to the conventional curve input (full stroke), the customer can also operate the press in the pendulum stroke for higher numbers of cycles.

An absolute new feature is the plausibility check integrated in the curve generator. Depending on the movement and load profile, all relevant data are checked automatically for compliance with the system-related limit values. If the system limit is met, the maximum machine speed is determined in the next step. This process check increases productivity and also additionally protects both the power electronics and the mechanical components.

During the check, among other things the linear movement of the ram and the rotating movement of the crankshaft are each examined in the curve generator with regard to their position, speed and acceleration. Other parameters such as inertia, change in force of the press, motor torque, current and power limits are also used for the check.

In addition to the new features, the Motion-Axis Servo Press template also implements tried and tested basic functions such as soft start and stop, stop in the top dead center, fast stop in the event of emergency off, automatic traversing to the top dead center and continuously adjustable traversing speed.

Conclusion
With its software template, Baumüller has for many years been consistently moving towards being a full-range solutions provider. In addition to the software package, the system solution for servo presses includes the complete main drive system with high-torque motors, servo converters, and mains rectifier units, including control cabinet construction, as well as the control technology with hardware.
