Output
Proportion of supply voltage to apply in fractional units between -1 and +1- Units: fractional
-
EnableFOC
Set to true to use FOC commutation (requires Phoenix Pro), which increases peak power by ~15% on supported devices (seeSupportsFOC). 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.
-
OverrideBrakeDurNeutral
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. -
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.
