Before reading this description, it is important to note the difference between the units of StallVelocity
and Velocity
.
Velocity
is a number between -1 and 1 with units of 'duty cycle'. It simply represents the average voltage across the motor.StallVelocity
represents a real velocity (e.g. m/s, RPM, etc.) and the units are determined by the RescaleFactor
. With a RescaleFactor
of 1, the default units would be in commutations per second.StallVelocity
property.StallVelocity
should be set to the lowest velocity you would expect from your motor. The controller will then monitor the motor's velocity, as well as the Velocity
, and prevent a 'dangerous stall' from occuring. If the controller detects a dangerous stall, it will immediately reduce the Velocity
(i.e. average voltage) to 0 and an error will be reported to your program.Velocity
is higher (i.e. when the average voltage across the motor is higher)StallVelocity
- motor velocity) becomes larger .StallVelocity
to 0 will turn off stall protection functionality.
