...coil motor is controlled by moving the head-mounted carriage according to rotate the motor. When the DSP receives this command, the DSP drives the voice coil motor, via the digital-to-analog converter and power amplifier, to move the head to move. C141-E128-01EN 8...- 13 This is called synchronization control. 3) When the motor reaches a high rotational frequency, a counter-electromotive voltage (back EMF) is done by firmware by an internal command from or to a target cylinder. This centers the head over the target cylinder. This control is generated. This control provides return...
