7. ROTATING DIRECTION DETECTION FUNCTION
The forward and reverse rotations of the MD are detected by the circuit, as shown in the above table.
The rotational direction of the MD can be learned by the output waveforms of the hall sensor and/or the driver.
If the hall sensors turn on in the order, H1
→
H2
→
H3, then this indicates reverse rotation. The output waveforms of the hall
sensors are as shown below.
Inversely, if the hall sensors turn on in the order, H3
→
H2
→
H1, then this shows forward rotation. The output waveforms of
the hall sensors are as shown below\.
