Functional Description
1.
Sensorless Drive
On receipt of PWM signal start instruction turn-on signal for forcible commutation (commutation
irrespective of the rotor position of the motor) is output and the motor starts to rotate. The rotation of the
motor causes induced voltage on the winding wire pin for each phase.
When signals indicating positive or negative for pin voltage (including induced voltage) for each phase
are input on the respective positional signal input pins, the turn-on signal for forcible commutation is
automatically switched to the turn-on signal for the positional signal (induced voltage).
Thereafter the turn-on signal is formed according to the induced voltage contained in the pin voltage so
as to drive the brushless DC motor.
2.
Starting commutation frequency (resonator pin and counter bit select pin)
The forcible commutation frequency at the time of start is determined by the resonator frequency and the
number of counter bits (within the IC).
Starting commutation frequency fst = Resonator frequency fxt/(6 × 2 (bit
+ 3)) bit = 14.
The forcible commutation frequency at the time of start can be adjusted using the inertia of the motor
and load.
The forcible commutation frequency should be set higher as the number of magnetic poles increases.
The forcible commutation frequency should be set lower as the inertia of the load increases.
3.
PWM Control
The PWM signal can be reflected in the turn-on signal by supplying the PWM signal from external
sources.
The frequency of the PWM signal should be set sufficiently high with regard to the electrical frequency of
the motor and in accordance with the switching characteristics of the drive circuit.
As positional detection is performed in synchronization with the rising edges of PWM signal, positional
detection cannot be performed with 0% duty or 100% duty.
