Ground on the MD30DC R2
Posted: Fri Jan 15, 2016 2:29 am
I am developing an Autonomous Guided Vehicle and bought 2 of your 30 A DC Motor Diver's (MD30DC R2).
I need to make sure that the ground pin for the microcontroller and the ground pin for the power supply on the driver are isolated. The power supply for the robot is 24 V DC. The motors draw 24 V DC and will essentially be dirty. The power for the high and low level controllers needs clean power which I should be able to provide (on the power supply side) with a buck converter that, in essence, has an isolated ground for the high and low voltage sides.
