LED Appearance	Description
Blinking	During normal operation this LED should blink at a rate between 0.5 Hz and several Hz reflecting the controller sample rate. A hesitation of disruption of the steady heartbeat pattern reflects a possible hardware or software issue. The first diagnostic question support will ask is "Is the Heartbeat LED blinking?"
Green	Green indicates normal operation with the motor in open loop mode or in tracking mode with the motor tracking properly.
Blue	Blue may occur in tracking mode if the rotor is not able to achieve the requested position and is experience rotor lead or lag.
Red	Red occurs if the rotor has experienced lead or lag for a duration greater than the rotor lead lag time and indicates a tracking problem.
