Chapter 6 Control Modes of Operation|ASDA-B Series
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.
6.3.2 Structure of Speed Control Mode
Basic Structure:
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:
