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.
Closed Loop control systems can handle a wide range of motions with a wide range of loads if the control system and mechanics 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 rather how to also get the desired performance.
OES (Optimal Engineering Systems, Inc.) has added vertical stages to their extensive line of high accuracy, high resolution lift stages. The Z110 Series of Z-axis Stages are available in travel strokes of 15 mm (0.590 in.), 30 mm (1.181 in.), 50 mm (1.969 in.), and 75 mm (2.953 in). These black anodized aluminum alloy stages feature preloaded crossed roller bearings and 1 mm per motor turn lead screws.
