E9 – Speed Range Error
OVERVIEW
During normal run time operation the value stored during auto calibration is used to
initially set the speed (e.g. target speed = 12 MPH, PWM ticks = Maximum PWM =
363). Once the speed stabilized the actual speed is monitored and if different than
the target speed the PWM value is adjusted until the actual speed matches the
target speed. If the PWM value is changed by more than the amount of ticks
required to change 0.8 MPH and the actual speed does not match the target speed
then an E9 error is flagged. This error indicates the motor controller system is
unable to maintain the target speed.
