(2)

Power save

The power save pin logic is as follows.

(3)

Reverse rotation detector

The construction of the reverse rotation detector circuit

is shown in Fig. 17.

Motor operation during reverse detection

When EC < ECR, forward rotation (right rotation)

When EC > ECR, reverse torque is applied to reduce speed (right rotation)

When the motor reverses, the reverse rotation detector operates, and the coil output is opened.

Free rotation in the reverse direction by inertia.

Stop

(1) Forward (EC < ECR)

The phase relationship between the hall input sig-

nals H2) and H3) is as shown in Fig.18, and the re-

verse rotation detector circuit does not operate.

(2) Reverse (EC > ECR)

The phase relationship between H2) and H3) is

opposite to that for forward rotation, and the re-

verse rotation detector circuit operates to switch the

output off and leave it in the open state.
