Function presets

FALCON supports flexible signal routing configurations for typical use cases. This is list of commonly used input configurations. They are also avaliable through Quick-setup pad and the acoustic menu. Note that both analog input (GPIO0) and servo PWM input (CH1) can be used. The system uses whichever of them has a valid signal.

info

The FALCON offers far richer functionality and plenty of fine-tuning options besides those presets. For full-fledged setup, please read the features

Aircraft​

Uni-directional prop control with freewheel. The controller works just as a "standard" BLDC ESC with "PWM" mapping and the usual freewheeling (no braking).

  • Restore default settings and keep everything as default.

RC Car with braking​

Common RC car with RC braking system. Negative input will result into torque brake. To reverse, first release the input (enter the center deadzone). Setting input to negative value then will start reversing.

  • Restore default settings
  • Set drvopts to 1
  • Set /pwm_input/center to 1500 and/or /analog_input/center to 2500 (values below will result into braking)
  • Set ctl_reverse_mode to 3
  • Set ctl_mode to 2

Bidirectional current (torque) mode​

Bidirectional, symmetrical control, mapped to current (torque). You may expect this behavior from a standard FOC motor control system.

  • Restore default settings
  • Set /pwm_input/center to 1500 and/or /analog_input/center to 2500 (values below will result into reversing)
  • Set ctl_mode to 2

Bidirectional voltage mode​

Bidirectional, symmetrical control, mapped to voltage. Useful to demonstrate the dynamic performance of the drive. Good choice for acrobatic performance.

  • Restore default settings
  • Set /pwm_input/center to 1500 and/or /analog_input/center to 2500 (values below will result into reversing)
  • Set ctl_mode to 1

Bidirectional speed closed loop​

Bidirectional, symmetrical control, mapped to speed reference (governor). Stabilize the speed in a closed loop.

  • Restore default settings
  • Set /pwm_input/center to 1500 and/or /analog_input/center to 2500 (values below will result into reversing)
  • Set ctl_mode to 17
