Formula for Face and Rim Alignment Calculation
Transcript of Formula for Face and Rim Alignment Calculation
F= bf B/D – br/2
R= bf A/D – br/2
For vertical adjustment Zeroed indicator on the top
Positive values for F & R indicate that motor must be raised. Opposite, negative values indicate that the motor must be lowered.
For horizontal adjustments Zeroed indicator on the left
Positive values for F& R indicate that the motor has to be moved to the left. Negative values for F&R indicate that the motor must be moved to the right.
