Generally, most users will prefer units of degrees or rotations. To determine an appropriate Rescale Factor, you will need to know the following values:
- Encoder pulses per revolution, equivalent to 4x the counts per revolution (CPR)
- Gearbox ratio (if applicable)
These values will be available from manufacturer data sheets, or directly on the motors/encoders.
Converting to Degrees
Specifications of system:
- Motor gear ratio: 76:1
- Encoder quadrature cycles per revolution (CPR): 300
- Encoder pulses per revolution = 300*4 = 1200
- Preferred Units: Degrees
Rescale Factor = 360 / (76*1200) = 0.003947368421
Converting to Rotations
Specifications of system:
- Motor gear ratio: 76:1
- Encoder quadrature cycles per revolution (CPR): 300
- Encoder pulses per revolution = 300*4 = 1200
- Preferred Units: Rotations
Rescale Factor = 1 / (76*1200) = 0.00001096491228
