Morgan Hill, CA – Motion Control -Lin Engineering is pleased to announce the Beta release of the new R1025 stepper motor driver. Combining high performance with a wide spectrum of features, the R1025 can be utilized with stepper motors of many shapes and sizes.

The R1025 microstepping driver is capable of output currents ranging from 0.8 to 10.0 amps peak while handling +12 to 80VDC of input voltage. With selectable step resolutions from Full stepping to 256x microstepping, the R1025 stepper driver is capable of stepping a typical 1.8 degree motor over 51,000 steps per revolution! The R1025 also boasts three selectable damping modes for smooth motion and three optically isolated inputs. One of the biggest advantages of the R1025 is its ease of use; with on-board DIP switches, there is no need to connect this device to a computer making set-up quick and simple.
