LED status indicators

The RGB LED gives a quick indication of device state.

CAN adapter

  • Blue: powered and operating.
  • Red: Error in communication, restart required.

Actuator

  • White: booting up.
  • Orange: initialized and waiting for commands over CAN.
  • Purple: USB connected; listening for commands over USB instead of CAN.
  • Blue: peripherals initialized. Drive not energized.
  • Green: drive active.
  • Red: an error requires attention.
  • Off: firmware update mode or no power.

LED state is a useful first check, but it does not replace SDK status and diagnostic information. If an actuator remains red, doesn't provide diagnostics over SDK, doesn't return to normal after a reboot, stop the actuator and contact support to avoid any further damage.
