Section 15 TSG2 (TSG20)
Generally, the state, when the motor rotation stops, is assumed to be a state of
the start and the control begins. First the fixed phase control is used to rotate
the motor from the stopped state. Afterwards, to accelerate the motor speed to
the fast rotation, the variable phase control is switched on. In combination with
encoder timer (ENCA) and the variable phase control, the timer output is
changed according to timing that is earlier than the change point of the hall
sensors (leading).
To decelerate the motor speed from fast rotation, the direction of control is
switched to deceleration control by rewriting only TSnIDC in TSnOPT0. When
the rotation count can be reduced to low-speed rotation, the rotation can be
placed in the stopped state by decreasing the PWM duty.
State transition is shown in Figure 15-81 and Figure 15-82.
