When the SPARK MAX is receiving a neutral command the idle behavior of the motor can be handled in two different ways: Braking or Coasting.
When in Brake Mode, the SPARK MAX will effectively short all motor wires together. This quickly dissipates any electrical energy within the motor and brings it to a quick stop.
When in Coast Mode, the SPARK MAX will effectively disconnect all motor wires. This allows the motor to spin down at its own rate.
The Idle Mode can be configured using the Mode Button, CAN, and USB interfaces.
Follow the steps below to switch the Idle Mode between Brake and Coast with the Mode Button.
Connect the SPARK MAX to main power, not just USB Power.
The Status LED will indicate which Idle Mode is currently configured by blinking blue or cyan for Brake and yellow or magenta for Coast depending on the motor type.
Press and release the Mode Button
You should see the Status LED change to indicate the selected Idle Mode.
Follow the steps below to switch the Idle Mode between Brake and Coast 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 application and verify that the application is connected to your SPARK MAX.
On the Basic tab, select the desired mode with the Idle Mode switch.
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.
