NOTE
 
1)  In speed control mode, if the users want to adjust analog speed input offset value, please refer to 
parameter 4-22 for the operation.

In the figure above, the speed command processing is used to select the command source of speed 
control according to chapter 6.3.1, including proportional gain (P1-40) and S-curve filter smoothing 
strategy of speed control. The speed control block diagram is used to manage the gain parameters of 
the servo drive and calculate the current input provided to motor instantaneously. The resonance 
suppression block diagram is used to suppress the resonance of mechanical system.  
The function and structure of speed command processing is shown as the figure below:
