1. LEDs 1, 2, and 3 sequence back and forth to indicate the processor is online and operational.
2. LED 4 is used as a discrete / analog signal to the upper console.
3. LED 5 indicates system status / mode. Currently 3 modes are defined safe mode, stand by mode and run mode. They are defined as
follows:
a) Safe Mode - When the controller's safety relay is not energized and no error exists, LED 5 remains off.
b) Stand By Mode - When the safety relay is engaged but the system is not outputting an active PWM to the motor and no error exists, LED 5
blinks off and on at a fast rate.
c) Run Mode - When the system outputs an active PWM Control signal to the motor and no error exists, LED 5 remains ON.
