Hi Mason,
[quote user="Mason Noh"]
1. PWM duty cycle range (datasheet: 0~100%)
what is minimum duty for stop? and maximum duty(recommended condition)?

Can you clarify this? Are you asking what is the minimum and maximum duty cycle that the motor can be stopped?
This normally depends on the motor and system design.

2. datasheet:
If it is changed while spinning, use gradual steps (for example, 1% increments), because a large
change in the commanded duty cycle can cause a large step in commutation, which can lock up the motor. This
behavior is typical with other industry devices.
: 2~5% is not available??

1% is a recommendation. This is also motor dependent.
