Class MotionMagicVelocityTorqueCurrentFOC

java.lang.Object
com.ctre.phoenix6.controls.MotionMagicVelocityTorqueCurrentFOC
All Implemented Interfaces:
ControlRequest, Cloneable
public final class MotionMagicVelocityTorqueCurrentFOC extends Object implements ControlRequest, Cloneable
Requests Motion Magic® to target a final velocity using a motion profile. This allows smooth transitions between velocity set points. Users can optionally provide a torque feedforward.

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

If the specified acceleration is zero, the Acceleration under Motion Magic® configuration parameter is used instead. This allows for runtime adjustment of acceleration for advanced users. Jerk is also specified in the Motion Magic® persistent configuration values. If Jerk is set to zero, Motion Magic® will produce a trapezoidal acceleration profile.

Target velocity can also be changed on-the-fly and Motion Magic® will do its best to adjust the profile. This control mode is based on torque current, so relevant closed-loop gains will use Amperes for the numerator.

  • Field Details

    • Velocity

      public double Velocity
      Target velocity to drive toward in rotations per second. This can be changed on-the fly.
      • Units: rotations per second

    • Acceleration

      public double Acceleration
      This is the absolute Acceleration to use generating the profile. If this parameter is zero, the Acceleration persistent configuration parameter is used instead. Acceleration is in rotations per second squared. If nonzero, the signage does not matter as the absolute value is used.
      • Units: rotations per second²

    • FeedForward

      public double FeedForward
      Feedforward to apply in torque current in Amperes. This is added to the output of the onboard feedforward terms.

      User can use motor's kT to scale Newton-meter to Amperes.

      • Units: A

    • Slot

      public int Slot
      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].

    • OverrideCoastDurNeutral

      public boolean OverrideCoastDurNeutral
      Set to true to coast 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 0A (zero torque).

    • LimitForwardMotion

      public boolean LimitForwardMotion
      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.

    • LimitReverseMotion

      public boolean LimitReverseMotion
      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.

    • IgnoreHardwareLimits

      public boolean IgnoreHardwareLimits
      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.

    • IgnoreSoftwareLimits

      public boolean IgnoreSoftwareLimits
      Set to true to ignore software limits, instead allowing motion.

      This can be useful when calibrating the zero point of a mechanism such as an elevator.

      The software limit faults will still report the values of the software limits regardless of this parameter.

    • UseTimesync

      public boolean UseTimesync
      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.

    • UpdateFreqHz

      public double UpdateFreqHz
      The frequency at which this control will update. This is designated in Hertz, with a minimum of 20 Hz (every 50 ms) and a maximum of 1000 Hz (every 1 ms). Some update frequencies are not supported and will be promoted up to the next highest supported frequency.

      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.
