Startup Control When the Motor is Stopped (Motor frequency
≤ 4 Hz)
The TB6582FG starts the motor operation with the operation instructions from VSP input and the
operating-mode-select circuit.
At startup, since the motor is not rotating, the motor is started applying forced commutation signal,
producing the induced voltage. When the induced-voltage frequency exceeds the forced commutation
frequency specified with the status of the FST pin, the motor starts to be driven in sensorless square-wave
mode. And when the phase current frequency reaches 6 Hz or higher, and the operating mode is switched to
sensorless sine-wave mode.
At startup, the rotor is aligned to a known position and the rotation is started in forced commutation mode.
The mode switching timing from DC excitation mode to forced commutation mode can be determined by an
external capacitor.
Since the durations of DC excitation and forced commutation vary depending on the motor type and motor
loading, experiments are required for proper adjustment.
