Motion controllers offer 100% rise in speed
Motion controllers controllers can give speed increases of up to 100%, while providing the platform for managing up to 32 axes and 32 co-ordinate systems.
Linear actuators replace pneumatics/hydraulics
Micromech said that its strong, fast and accurate linear actuators can replace pneumatics or hydraulics and provide smooth motion, accurate positioning and quiet operation.
The series includes optically isolated step and direction inputs and the drives are configured by either on-board switches or via the Graphical User Interface (GUI).
This means a wide range of stepper motors can be set up with the on-board switches as the GUI is perfect when using any manufacturers alternative motor type or one with a unique winding.
Highlights include; Open Loop Stall Detect (OLSD) allows detection of a stalled motor without an encoder or resolver.
