Calibration (Payout & Speed)
Calibration of the quadrature input to give the payout and speed values may need to be calculated manually to
suit the mechanical hardware. A simple Auto Calibration section is supplied to calculate basic gains based on the
number of actuators and wheel diameter but this calculation is limited to the engineering units used for the wheel
diameter. For example, if the wheel diameter is entered in metres then the Auto Calibration will provide gain
values to give Payout in metres and Speed in metres per second. Manual alterations to the gain may be
required if you require these values in other engineering units.
