During self test, the LEDs will display the controller’s soft- ware revision number by flashing a sequence of digits as shown in the figure below. Then each motor will, in turn, be ramped to maximum forward and maximum reverse. When the motors are operating, the LED will display one of the patterns described in Table 18. The cycle will repeat indefinitely until the controller is powered Off or reset.
