Closed-loop control systems can handle a wide range of motions with a wide range of loads if the control system and the mechanics of the system are properly designed for the task. A couple of the more difficult combinations to design for are high inertial mismatches and backlash with hard gearing. The question is not just how to make the system stable but also how to get the desired performance. 

Thomson Industries, Inc. has released a true collaborative extension of cobots. The new Movotrak CTU 7th axis features collision detection settings for programming and control benefits. An industrial robot transfer unit (RTU) has also launched, which can be easily integrated with a user’s preferred motor and drive. Adding a horizontal operating range up to 10 meters, the Movotrak cobot transfer unit (CTU) sets itself apart with collision detection that stops the cobot when it encounters an obstacle, facilitating collaboration and increasing productivity. 

A motion controller with even more possibilities: With the new MC 3602 B and MC 3606 B motion controllers, the selection and commissioning of drive systems is now even simpler. With the compact MC 3602/06 B, DC-motors, brushless DC-motors and linear motors can be operated with the typical position encoders as servo drive in accordance with CiA 402. Also new is the support of stepper motors with encoder as servo or without encoder in open-loop operation. The products "speak" EtherCAT, CANopen, RS232 and USB.
