I am using a polulu G2 high power motor driver 18x18 to control a DC motor. I am controlling the system with an arduino and powering the system with a 24V switching power supply.
Now I want to add a DC switch in my design that allows me to switch between powering the motor controller and powering the DC motor directly. So effectively if I flip the switch, the motor controller is powered down and the DC motor is directly connected to the power supply (with some manual control button in between to turn it on or of). I have attached a simple drawing to illustrate.
My question is: if I flip the switch, the motor will be powered directly, but the M1A and M1B ports of the motor controller will also be directly connected to the 24V from the power supply. Will this be a problem? Can the board handle this?
