Hi Hoa,
Can you provide a scope capture of the two outputs? This will help determine what could be causing this.
What is the motor specifications? R/L
If the current is too high when starting, the overcurrent may be causing a problem. Look for the outputs to disable for approximately 3ms
If the current is less than the overcurrent, overtemperature could be causing the problem.
