Connecting Power and Motors to the Controller

Note:

Both VMot terminals are connected to each other in the board and must be wired to the same voltage.

Controller Power

The AX500 uses a flexible power supply scheme that is best described in Figure 8. In this diagram, it can be seen that the power for the Controller’s processor is separate from this of the motor drivers. In typical applications, the VMot is connected in permanence to the battery while VCon is connected to the battery through a On/Off switch.
