US Digital has released the new MD3 Programmable Microstepping Motor Driver, capable of driving motors from NEMA size 14 to 42. The MD3 accepts 9 to 50 Vdc power inputs and is rated for currents up to 7 A continuous duty.
In addition to digital input controls, the MD3 can be configured and controlled using the open MODBUS RTU protocol over an RS485 bus. A GUI application is supplied that allows a range of settings to be changed including the number of microsteps per full step, acceleration/deceleration rates, speed and current cutback.
The design supports multiple MD3 units on the same RS485 bus and allows for programmable motion profiles. In addition, the MD3 has a brushed dc motor speed control mode.
