CoreTalonFXSetControl(DifferentialVelocityVoltage) Method

Request PID to target velocity with a differential position setpoint.

This control mode will set the motor's velocity setpoint to the velocity specified by the user. It will also set the motor's differential position setpoint to the specified position.

DifferentialVelocityVoltage Parameters

  • TargetVelocity – Average velocity to drive toward in rotations per second.
  • DifferentialPosition – Differential position to drive toward in rotations.
  • EnableFOC – Set to true to use FOC commutation (requires Phoenix Pro), which increases peak power by ~15%. Set to false to use trapezoidal commutation. FOC improves motor performance by leveraging torque (current) control. However, this may be inconvenient for applications that require specifying duty cycle or voltage. CTR-Electronics has developed a hybrid method that combines the performances gains of FOC while still allowing applications to provide duty cycle or voltage demand. This not to be confused with simple sinusoidal control or phase voltage control which lacks the performance gains.
  • TargetSlot – Select which gains are applied to the primary controller by selecting the slot. Use the configuration api to set the gain values for the selected slot before enabling this feature. Slot must be within [0,2].
  • DifferentialSlot – Select which gains are applied to the differential controller by selecting the slot. Use the configuration api to set the gain values for the selected slot before enabling this feature. Slot must be within [0,2].
  • OverrideBrakeDurNeutral – Set to true to static-brake the rotor when output is zero (or within deadband). Set to false to use the NeutralMode configuration setting (default). This flag exists to provide the fundamental behavior of this control when output is zero, which is to provide 0V to the motor.
