Controller Powering Schemes

The table below shows the state of the controller depending on the voltage applied to Vcon and Vmot.

TABLE 2. Controller status depending on Vcon and Vmot voltage

VCon	VMot	Controller Status
Off	Off	Off

Off	5-24V	Off

8-24V	Off	Controller MCU is On. Controller will communicate but motors
		cannot be activated

8-24V	5-24V	Controller is On and motors are activated

Controller Powering Schemes

Powering the Controller from a single Battery

The diagram on Figure 19 show how to wire the controller to a single battery circuit and how to turn power On and Off.

			Controller							Motor Battery

Notes:

-The Battery Power connection are doubled in order to provide the maximum current to the controller. If only one motor is used, only one set of motor power cables needs to be connected.

-Typically, 1 or 2 x 12V batteries are connected in series to reach 12 or 24V respectively.
