Talon FXS

Talon FXS is a versatile motor controller compatible with the CTRE software ecosystem. This standalone device seamlessly supports both brushless and brushed motors, offering unparalleled flexibility and performance.

The Talon FXS supports the CTR Electronics Minion and other third-party motors. Talon FXS also employs methods to reduce hall sensor velocity measurement noise and phase delay - a common problem with similar standalone motor controllers.

Phoenix Pro users also benefit with “Advanced Hall Support” which can increase motor peak efficiency as high as an additional 2% percentage points and further reduce velocity measurement noise, making it ideal for velocity closed loop modes.

Blink Codes
Disabled Codes
Animation (Click to play) LED State Cause Possible Fix
LEDs Off No Power Provide 12V to Red/Black leads.
Blinking Alternating Red Talon FXS does not have a valid CAN/PWM signal. Ensure good connections between CANH and CANL (Yellow and Green) & robot controller is on.
Blinking Alternating Orange TalonFXS detects CAN but does not see Phoenix running on the robot controller. If Phoenix is running on the robot controller, ensure good connection between the controller and this device. Otherwise, deploy a robot program that uses Phoenix.
Blinking Simultaneous Orange Talon FXS has valid CAN signal and is disabled. Phoenix is running in robot controller and Talon FXS has good CAN connection to robot controller. If robot is enabled, ensure a control request is being sent to the Talon FXS.
Enabled Codes
Both Solid Orange Talon FXS enabled with neutral output.
Blinking Simultaneous Red Talon FXS driving in reverse. Rate of blink corresponds to duty cycle applied.
Blinking Simultaneous Green Talon FXS driving forward. Rate of blink corresponds to duty cycle applied.
Offset Alternating Red/Off Talon FXS limited (hard or soft limit). Direction of offset determines forward/reverse limit.
Special Codes
Offset Orange/Off Talon FXS in thermal cutoff or temperature measurement is missing. Please see "Troubleshooting Fault LED" for potential solutions.
Alternate Red/Green Talon FXS driven with Pro-only command while unlicensed. Use non-Pro-only command, or license device for Pro.
Alternate Orange/Green Talon FXS driven with no motor selected in motor arrangement. Configure the Talon FXS with the attached motor.
Alternate Red/Orange Damaged Hardware. Contact CTRE.
Single LED alternates Green/Orange Talon FXS in bootloader. Field-upgrade device in Tuner X.

Troubleshooting Fault LED

A Talon FXS thermal fault, as indicated with an “Offset Orange/Off” blink code, can be triggered for a variety of reasons. The following list can be used to help identify the reason and a potential solution.

  • Brushless Motor

    • JST is disconnected or damaged. Plug-in the motor JST cable into the JST port and ensure the cable is not damaged.

    • Motor arrangement is incorrect. Please select the correct motor in configs.

    • Talon FXS or motor has reached thermal cut-off. Allow time for the device to cool and consider configuring a Stator Current limit.

  • Brushed Motor

    • Motor arrangement is incorrect. Please select one of the brushed options in configs.

    • Talon FXS has reached thermal cut-off. Allow time for the device to cool and consider configuring a Stator Current limit.
