Class DynamicMotionMagicTorqueCurrentFOC
- All Implemented Interfaces:
ControlRequest,Cloneable
Motion Magic® produces a motion profile in real-time while attempting to honor the specified Cruise Velocity, Acceleration, and (optional) Jerk. 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
Position to drive toward in rotations.- Units: rotations
-
Velocity
Cruise velocity for profiling. The signage does not matter as the device will use the absolute value for profile generation.- Units: rotations per second
-
Acceleration
Acceleration for profiling. The signage does not matter as the device will use the absolute value for profile generation.- Units: rotations per second²
-
Jerk
Jerk for profiling. The signage does not matter as the device will use the absolute value for profile generation.Jerk is optional; if this is set to zero, then Motion Magic® will not apply a Jerk limit.
- Units: rotations per second³
-
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
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
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
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
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
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
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
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
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.
