Run Auto-Calibration; E9 - Speed Range Error - Vision Fitness T9800S Engineering Manual

DGF1J Upper Board: Engineering Guide
5.3.4 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 .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.
