Brushed and brushless DC motors require different motor control schemes based on the differences in their technology. It is possible to damage the SPARK MAX, the motor, or both if the appropriate motor type isn't configured properly. At the moment, the NEO Brushless Motor and the NEO 550 Brushless Motor are the only FRC-legal brushless motors compatible with the SPARK MAX, so choosing the correct operating mode should be straightforward.
Brushed or brushless motor types can be configured using the Mode Button, CAN, and USB interfaces.
Follow the steps below to switch motor types with the Mode Button. It is recommended that the motor be left disconnected until the correct mode is selected.
Connect the SPARK MAX to main power, not just USB Power.
The Status LED will indicate which motor type is configured by blinking yellow or blue for Brushed Mode, or blinking magenta or cyan for Brushless Mode.
Press and hold the Mode Button for approximately 3 seconds.
After the button has been held for enough time, the Status LED will change and indicate the different motor type.
Release the mode button.
Follow the steps below to switch motor types with the USB and the REV Hardware Client application. Be sure to download and install the REV Hardware Client application before continuing.
Connect the SPARK MAX to your computer using a USB-C cable.
Open the REV Hardware Client and verify that the application is connected to your SPARK MAX.
On the Basic tab, select the appropriate motor type under the Select Motor Type menu.
Click Update Configuration and confirm the change.
Please see the API Information for information on how to configure the SPARK MAX using the CAN interface.
