All Implemented Interfaces:
Cloneable
public class MotionMagicTorqueCurrentFOC extends ControlRequest implements Cloneable
Requires Phoenix Pro; Requests Motion Magic® to target a final position using a motion profile. Users can optionally provide a torque current 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 based on torque current, so relevant closed-loop gains will use Amperes for the numerator.

  • Field Details

    • Position

      public double Position
      Position to drive toward in rotations.
      • Units: rotations

    • FeedForward

      public double FeedForward
      Feedforward to apply in torque current in Amperes. 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.

    • 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 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.
