Note that the SD540 uses the following bounds for PWM values. These
values should work reasonably well for most controllers, but if users
experience issues such as asymmetric behavior around the deadband or
inability to saturate the controller in either direction, calibration is
recommended. The calibration procedure can be found in the SD540 User
Manual available from Mindsensors.
