3.4.2Drive Circuit for Read Motor

Fig. 3-9

This circuit controls the rotation/stoppage and the direction of rotation, excitation mode and motor cur- rent of the read motor.

A drive clock signal (RMOT-CLK) and rotation direction signal (RMOT-CW/CCW) are input to control the speed and direction of the motor rotation.

When the level of the enabling signal (RMOT-Enable) is set to "L", motor current is turned to OFF regardless of the state of other signals.

For the excitation mode, either of 2 phase excitation, 1-2 phase excitation, W1-2 phase excitation, 2W1-2 phase excitation or the 4W1-2 phase excitation can be selected using the excitation switching signal (RMOT-Mode1/RMOT-Mode2).

The edge switching signal (RMOT-Mode3) is used to specify the switching timing for excitation phase either from when both the rise and decay edge of the CLK input are detected or when only the rising edge is detected.

Motor current value can be set discretionary by changing the level of the reference setting signal (RMOT-REF).
