In order to ensure shorter delivery times even with decreasing batch sizes, many manufacturing companies have to convert their production machines more and more often: spindles have to be adjusted, stops moved and sensors positioned. That requires machines with automatic Format adjustment, The actuator MSBA from Baumer solves this task particularly space-saving, because with only 42 mm diameter it is the smallest of its class.It consists of a geared motor, position controller and CANopen interface. He reaches a new goal reliably and quickly. The dynamic overload protection through speed limitation (I2t control) protects against overload. Thanks to the absolute multiturn position detection, there is no need for reference switches and movements. Even if it is moved in the de-energized state, the position is not lost. The digital hardware inputs can be freely programmed, for example to manually start the position run in service mode. Additional functions such as current limiting and intelligent blockage management enable the machine builder to make the system safer and more efficient.
