The below text describes the sequence of actions that can occur:
IF (Static Zero Offset test) THEN
Measure the Static Zero Offset;
Save as Zero Offset compensation value if within limits;
ENDIF
IF (Dynamic Zero Offset test OR Angle test) THEN
First run in the forward direction and then in the backward direction;
Measure average torque and angle pulses in both directions;
IF (Dynamic Zero Offset test) THEN
Check the measured Dynamic Zero Offset;
Save as Zero Offset compensation value if within limits;
ENDIF
IF (Angle test) THEN
Check that both the measured angles are within specified limits;
ENDIF
ENDIF
IF (Flying Zero Offset test) THEN
Run forward a programmable time from the start of the diagnostic step (do not measure);
Start measuring the torque and run another programmable time;
