class phoenix6.controls.DutyCycleOut(output: float, enable_foc: bool = True, override_brake_dur_neutral: bool = False, limit_forward_motion: bool = False, limit_reverse_motion: bool = False)#

Request a specified motor duty cycle.

This control mode will output a proportion of the supplied voltage which is supplied by the user.

Parameters:

output (float) – Proportion of supply voltage to apply in fractional units between -1 and +1
enable_foc (bool) –
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.
override_brake_dur_neutral (bool) – 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.
limit_forward_motion (bool) – 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.
limit_reverse_motion (bool) – 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.

class phoenix6.controls.TorqueCurrentFOC(output: phoenix6.units.ampere, max_abs_duty_cycle: float = 1.0, deadband: phoenix6.units.ampere = 0.0, override_coast_dur_neutral: bool = False, limit_forward_motion: bool = False, limit_reverse_motion: bool = False)#

Requires Phoenix Pro; Request a specified motor current (field oriented control).

This control request will drive the motor to the requested motor (stator) current value. This leverages field oriented control (FOC), which means greater peak power than what is documented. This scales to torque based on Motor’s kT constant.

Parameters:

output (ampere) – Amount of motor current in Amperes
max_abs_duty_cycle (float) – The maximum absolute motor output that can be applied, which effectively limits the velocity. For example, 0.50 means no more than 50% output in either direction. This is useful for preventing the motor from spinning to its terminal velocity when there is no external torque applied unto the rotor. Note this is absolute maximum, so the value should be between zero and one.
deadband (ampere) – Deadband in Amperes. If torque request is within deadband, the bridge output is neutral. If deadband is set to zero then there is effectively no deadband. Note if deadband is zero, a free spinning motor will spin for quite a while as the firmware attempts to hold the motor’s bemf. If user expects motor to cease spinning quickly with a demand of zero, we recommend a deadband of one Ampere. This value will be converted to an integral value of amps.
override_coast_dur_neutral (bool) – 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).
limit_forward_motion (bool) – 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.
limit_reverse_motion (bool) – 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.

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 Jerk value 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.

Parameters:

position (rotation) – Position to drive toward in rotations.
enable_foc (bool) –
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.
feed_forward (float) – Feedforward to apply in fractional units between -1 and +1.
slot (int) – 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].

This flag exists to provide the fundamental behavior of this control when output is zero, which is to provide 0V to the motor.
limit_forward_motion (bool) – 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.
limit_reverse_motion (bool) – 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.

class phoenix6.controls.MotionMagicVelocityDutyCycle(velocity: phoenix6.units.rotations_per_second, acceleration: phoenix6.units.rotations_per_second_squared = 0.0, enable_foc: bool = True, feed_forward: float = 0.0, slot: int = 0, override_brake_dur_neutral: bool = False, limit_forward_motion: bool = False, limit_reverse_motion: bool = False)#

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 duty cycle feedforward.

Motion Magic® Velocity produces a motion profile in real-time while attempting to honor the specified Acceleration and Jerk value. 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 duty cycle based, so relevant closed-loop gains will use fractional duty cycle for the numerator: +1.0 represents full forward output.

Parameters:

velocity (rotations_per_second) – Target velocity to drive toward in rotations per second. This can be changed on-the fly.
acceleration (rotations_per_second_squared) – 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.
enable_foc (bool) –
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.
feed_forward (float) – Feedforward to apply in fractional units between -1 and +1.
slot (int) – 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].
override_brake_dur_neutral (bool) – 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.
limit_forward_motion (bool) – 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.
limit_reverse_motion (bool) – 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.

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 voltage feedforward.

Motion Magic® Velocity produces a motion profile in real-time while attempting to honor the specified Acceleration and Jerk value. 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 voltage-based, so relevant closed-loop gains will use Volts for the numerator.

Parameters:

velocity (rotations_per_second) – Target velocity to drive toward in rotations per second. This can be changed on-the fly.
acceleration (rotations_per_second_squared) – 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.
enable_foc (bool) –
Set to true to use FOC commutation (requires Phoenix Pro), which increases peak power by ~15%. Set to false to use trapezoidal commutation.

class phoenix6.controls.DynamicMotionMagicDutyCycle(position: phoenix6.units.rotation, velocity: phoenix6.units.rotations_per_second, acceleration: phoenix6.units.rotations_per_second_squared, jerk: phoenix6.units.rotations_per_second_cubed, enable_foc: bool = True, feed_forward: float = 0.0, slot: int = 0, override_brake_dur_neutral: bool = False, limit_forward_motion: bool = False, limit_reverse_motion: bool = False)#

Requires Phoenix Pro and CANivore; Requests Motion Magic® to target a final position using a motion profile. This dynamic request allows runtime changes to Cruise Velocity, Acceleration, and Jerk. Users can optionally provide a duty cycle feedforward. This control requires use of a CANivore.

Motion Magic® produces a motion profile in real-time while attempting to honor the specified Cruise Velocity, Acceleration, and Jerk value. 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.

Parameters:

position (rotation) – Position to drive toward in rotations.
velocity (rotations_per_second) – Cruise velocity for profiling. The signage does not matter as the device will use the absolute value for profile generation.
acceleration (rotations_per_second_squared) – Acceleration for profiling. The signage does not matter as the device will use the absolute value for profile generation
jerk (rotations_per_second_cubed) – Jerk for profiling. The signage does not matter as the device will use the absolute value for profile generation
enable_foc (bool) –
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.
feed_forward (float) – Feedforward to apply in fractional units between -1 and +1.
slot (int) – 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].
override_brake_dur_neutral (bool) – 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.
limit_forward_motion (bool) – 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.
limit_reverse_motion (bool) – 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.

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:: new_slot (int) – Parameter to modify
Returns:: Itself
Return type:: DynamicMotionMagicTorqueCurrentFOC

with_override_coast_dur_neutral(new_override_coast_dur_neutral: bool) → DynamicMotionMagicTorqueCurrentFOC#

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

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).

Parameters:: new_override_coast_dur_neutral (bool) – Parameter to modify
Returns:: Itself
Return type:: DynamicMotionMagicTorqueCurrentFOC

with_limit_forward_motion(new_limit_forward_motion: bool) → DynamicMotionMagicTorqueCurrentFOC#

Modifies this Control Request’s limit_forward_motion 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:: new_limit_forward_motion (bool) – Parameter to modify
Returns:: Itself
Return type:: DynamicMotionMagicTorqueCurrentFOC

with_limit_reverse_motion(new_limit_reverse_motion: bool) → DynamicMotionMagicTorqueCurrentFOC#

Modifies this Control Request’s limit_reverse_motion 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:: new_limit_reverse_motion (bool) – Parameter to modify
Returns:: Itself
Return type:: DynamicMotionMagicTorqueCurrentFOC

with_update_freq_hz(new_update_freq_hz: phoenix6.units.hertz) → DynamicMotionMagicTorqueCurrentFOC#

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:: new_update_freq_hz (hertz) – Parameter to modify
Returns:: Itself
Return type:: DynamicMotionMagicTorqueCurrentFOC
