The Talon 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 Talon User Manual available from CTRE.
