The digital ASIC continuously provides HIGH or OPEN signal until the Back-EMF generated is large enough to produce the
FG signal for the self commutation. During a fixed time, if the Back-EMF generated is too small and the spindle motor is not
driven by the self commutation, the ASIC resets all signals sent and retries the spindle.
Notes:
1. CNTL1: Spindle motor control
2. CNTL2: commutation mode control
3. CNTL3; VCM control
4. “1”: Enable; “0”: disable;
Acceleration Mode
When the Back-EMF detected is large enough to determine motor position, the mode is changed from start-up to acceleration.
The ASIC sends the optimum commutation timing signal via MCLK according to the FG input.
By using the Back-EMF, the spindle is self-commuted at acceleration and running modes. During the motor drive, the spindle
motor is commuted at that point which is electrically 30
°
delayed after the FG_Edge.
Running Mode
The running mode is when the spindle motor speed arrives within
±
1% of the target speed. The commutation mode, commu-
tation delay time, MCLK delay time (Td) and masking time are changed at the running mode.
The spindle motor speed is controlled by PWM signal within
±
0.01%.
The soft commutation using the current slope of the motor may reduce audiable noise, EMI (Electromagnetic Interference) and
spark voltage which is generated on the motor coil at the commutation.
