Lin Engineering (Morgan Hill, CA) offers the R525 stepper motor driver that reduces overall design time and system cost for an array of step motor applications needing high torque, power, and smooth motion. Measuring 3.3 × 1.3", the driver is accommodated into most systems. It provides up to 5 amps peak of current, handles up to 75VDC, and is capable of up to 256x microstepping with a standard 1.8° motor. It features builtin RS-485 communication, and can be connected to a computer and configured via a graphical user interface, LinDriver. Configurable settings include step resolution, run current, hold current, damping modes, and sensing step pulses on the rising edge or falling edge.
