Hi Nate,
Q1) what is best Acceleration rate and time base value?
When I tune both value, noise same exist...
What type of noise are you experiencing (audible, electrical, mechanical)?
The acceleration rate depends on the motor manufacturers specifications and load.
Q2) As below current waveform of A+ from motor output, below what is red circle component?
The red circle component is the current ripple during fast decay. This can be seen if you zoom in and compare the output with the current. The current will reach the trip point and then decay for the remainder of the PWM cycle. The next PWM cycle will insert current into the winding until the trip point is reach and the decay mode will begin again.
