The MD3 programmable microstepping motor driver can drive motors from NEMA size 14 to 42

The MD3 programmable microstepping motor driver can drive motors from NEMA size 14 to 42. It accepts 9-50 Vdc power inputs and is rated for currents up to 7 A continuous duty. In addition to digital input controls, the driver can be configured and controlled using the open Modbus RTU protocol over a RS-485 bus. A GUI application is supplied that allows many settings to be changed, including the number of microsteps per full step, acceleration/deceleration rates, speed and current cutback. The design supports multiple units on the same RS-485 bus and allows for programmable motion profiles. The driver also has a brushed dc motor speed control mode.
