If the magnetic direction field exceeds

respectively, depending on the direction of rotation.

If the magnitude of the magnetic direction field is below

magnitudes of the magnetic differential field below

Speed pulse occur only at the first pulse after start up or above

f

If no magnetic differential signal change is detected the IC will remain in calibrated mode.

No internal reset are generated - therefore a zero speed operation is possible.
