Chapter 6 Control Modes of OperationASDA-B Series

The command source is selected according to the state of SPD0, SPD1 and parameter P1-01 (S or Sz). Whenever the command signal needs to be more smoothly, we recommend the users to use S-curve and low-pass filter.

6.3.3 Smoothing Strategy of Speed Control Mode

S-curve Filter

The S-curve filter is a speed smoothing command which provides 3 steps accel / decel S-curve to smooth the speed command change of the motor during acceleration and deceleration. Using S-curve filter can let the servo motor run more smoothly in response to a sudden speed command change. Since the speed and acceleration curve are both continuous, in order to avoid the mechanical resonance and noise may occur due to a sudden speed command (differentiation of acceleration), using S-curve filter not only can improve the performance when servo motor accelerate or decelerate but also can make the motor run more smoothly. S-curve filter parameters include P1-34 Acceleration Time (TACC), P1-35 Deceleration Time (TDEC) and Accel /Decel S-curve (TSL), and the users can use these three parameters to improve the motor performance during acceleration, deceleration and operation. ASDA-B series servo drives also support the time calculation of completing speed command. T (ms) is the operation (running) time. S (rpm) is absolute speed command, i.e. the absolute value (the result) after starting speed subtracts the final speed.
