Detailed Description

Requests Motion Magic® to target a final position using a motion profile.

Users can optionally provide a duty cycle feedforward.

Motion Magic® produces a motion profile in real-time while attempting to honor the Cruise Velocity, Acceleration, and (optional) Jerk specified via the Motion Magic® configuration values. This control mode does not use the Expo_kV or Expo_kA configs.

Target position can be changed on-the-fly and Motion Magic® will do its best to adjust the profile. This control mode is duty cycle based, so relevant closed-loop gains will use fractional duty cycle for the numerator: +1.0 represents full forward output.

Member Function Documentation

◆ GetControlInfo()

std::map< std::string, std::string > ctre::phoenix6::controls::MotionMagicDutyCycle::GetControlInfo ( ) const

inlineoverridevirtual

Gets information about this control request.

Returns: Map of control parameter names and corresponding applied values

Implements ctre::phoenix6::controls::ControlRequest.

◆ ToString()

std::string ctre::phoenix6::controls::MotionMagicDutyCycle::ToString ( ) const

inlineoverridevirtual

Returns a string representation of the object.

Returns: a string representation of the object.

Implements ctre::phoenix6::controls::ControlRequest.

◆ WithEnableFOC()

MotionMagicDutyCycle & ctre::phoenix6::controls::MotionMagicDutyCycle::WithEnableFOC ( bool newEnableFOC )

inline

Modifies this Control Request's EnableFOC parameter and returns itself for method-chaining and easier to use request API.

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.

Parameters

newEnableFOC Parameter to modify

Returns: Itself

◆ WithFeedForward()

MotionMagicDutyCycle & ctre::phoenix6::controls::MotionMagicDutyCycle::WithFeedForward ( units::dimensionless::scalar_t newFeedForward )

inline

Modifies this Control Request's FeedForward parameter and returns itself for method-chaining and easier to use request API.

Feedforward to apply in fractional units between -1 and +1.

Parameters

newFeedForward Parameter to modify

Returns: Itself

◆ WithIgnoreHardwareLimits()

MotionMagicDutyCycle & ctre::phoenix6::controls::MotionMagicDutyCycle::WithIgnoreHardwareLimits ( bool newIgnoreHardwareLimits )

inline

Modifies this Control Request's IgnoreHardwareLimits parameter and returns itself for method-chaining and easier to use request API.

Set to true to ignore hardware limit switches and the LimitForwardMotion and LimitReverseMotion parameters, instead allowing motion.

This can be useful on mechanisms such as an intake/feeder, where a limit switch stops motion while intaking but should be ignored when feeding to a shooter.

The hardware limit faults and Forward/ReverseLimit signals will still report the values of the limit switches regardless of this parameter.

Parameters

newIgnoreHardwareLimits Parameter to modify

Returns: Itself

◆ WithLimitForwardMotion()

MotionMagicDutyCycle & ctre::phoenix6::controls::MotionMagicDutyCycle::WithLimitForwardMotion ( bool newLimitForwardMotion )

inline

Modifies this Control Request's LimitForwardMotion parameter and returns itself for method-chaining and easier to use request API.

Set to true to force forward limiting. This allows users to use other limit switch sensors connected to robot controller. This also allows use of active sensors that require external power.

Parameters

newLimitForwardMotion Parameter to modify

Returns: Itself

◆ WithLimitReverseMotion()

MotionMagicDutyCycle & ctre::phoenix6::controls::MotionMagicDutyCycle::WithLimitReverseMotion ( bool newLimitReverseMotion )

inline

Modifies this Control Request's LimitReverseMotion parameter and returns itself for method-chaining and easier to use request API.

Set to true to force reverse limiting. This allows users to use other limit switch sensors connected to robot controller. This also allows use of active sensors that require external power.

Parameters

newLimitReverseMotion Parameter to modify

Returns: Itself

◆ WithOverrideBrakeDurNeutral()

MotionMagicDutyCycle & ctre::phoenix6::controls::MotionMagicDutyCycle::WithOverrideBrakeDurNeutral ( bool newOverrideBrakeDurNeutral )

inline

Modifies this Control Request's OverrideBrakeDurNeutral parameter and returns itself for method-chaining and easier to use request API.

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.

Parameters

newOverrideBrakeDurNeutral Parameter to modify

Returns: Itself

◆ WithPosition()

MotionMagicDutyCycle & ctre::phoenix6::controls::MotionMagicDutyCycle::WithPosition ( units::angle::turn_t newPosition )

inline

Modifies this Control Request's Position parameter and returns itself for method-chaining and easier to use request API.

Position to drive toward in rotations.

Parameters

newPosition Parameter to modify

Returns: Itself

◆ WithSlot()

MotionMagicDutyCycle & ctre::phoenix6::controls::MotionMagicDutyCycle::WithSlot ( int newSlot )

inline

Modifies this Control Request's Slot parameter and returns itself for method-chaining and easier to use request API.

Select which gains are applied 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].

Parameters

newSlot Parameter to modify

Returns: Itself

◆ WithUpdateFreqHz()

MotionMagicDutyCycle & ctre::phoenix6::controls::MotionMagicDutyCycle::WithUpdateFreqHz ( units::frequency::hertz_t newUpdateFreqHz )

inline

Sets the period at which this control will update at.

This is designated in Hertz, with a minimum of 20 Hz (every 50 ms) and a maximum of 1000 Hz (every 1 ms).

If this field is set to 0 Hz, the control request will be sent immediately as a one-shot frame. This may be useful for advanced applications that require outputs to be synchronized with data acquisition. In this case, we recommend not exceeding 50 ms between control calls.

Parameters

newUpdateFreqHz Parameter to modify

Returns: Itself

◆ WithUseTimesync()

MotionMagicDutyCycle & ctre::phoenix6::controls::MotionMagicDutyCycle::WithUseTimesync ( bool newUseTimesync )

inline

Modifies this Control Request's UseTimesync parameter and returns itself for method-chaining and easier to use request API.

Set to true to delay applying this control request until a timesync boundary (requires Phoenix Pro and CANivore). This eliminates the impact of nondeterministic network delays in exchange for a larger but deterministic control latency.

This requires setting the ControlTimesyncFreqHz config in MotorOutputConfigs. Additionally, when this is enabled, the UpdateFreqHz of this request should be set to 0 Hz.

Parameters

newUseTimesync Parameter to modify

Returns: Itself
