4  BRAKE OPERATION TIMING CHART 

STDF PD controls Brake by Drive automatically. 

Please refer to below Timing Chart when Brake is controlled by the upper controller other 
than using STDF PD Brake control. Otherwise, Drive malfunctioning and loads can be fall 
down.  

Also, please do not operate Brake while motor operation to prevent damage.
