Modernisation becomes child’s play

STOBER now offers its CiA 402 application with all operating modes defined in the standardised CiA 402 device profile. Velocity mode is now integrated, bringing back an older operating mode. This provides the user with an all-in-one solution for both controller-based and classic drive-based applications. This complete solution is especially helpful for modernising existing machines.

The internationally standardised device profile CiA 402 is suitable for both controller-based and drive-based applications. Using the included controller-based operating modes, users can implement applications with synchronized, cyclic set value specification by a motion controller.

In addition, the drive controllers can also independently handle motion tasks, such as referencing during commissioning. The drive-based operating modes of CiA 402, on the other hand, offer complete movement calculation and design in the drive. In this setup, the set values for position, velocity and torque/force are converted into movements accurately and precisely.

“We have been using the device profile for our drive controllers for a long time,” says STOBER’s Lutz Augenstein. “This simplifies our customers’ work and time-consuming programming is no longer necessary.”

In the past, the CANopen device profile has adapted to the current requirements of the market. As a result, new operating modes were added over the years. Older ones are usually no longer required for modern machines, which is why many manufacturers of newer devices no longer implement them. Velocity mode, which allows the drive to be controlled using a set velocity, and Interpolated position mode, which is used to synchronize multiple axes, are two such modes.

Augenstein says: “Without the aforementioned standardised operating modes, modernising existing machines becomes a challenge for operators.”
