ASDA-B2
Settings:
This parameter is used to make the motor run more smoothly when startup and
windup. Using this parameter can improve the motor running stability.
TACC: P1-34, Acceleration time
TDEC: P1-35, Deceleration time
TSL: P1-36, Accel /Decel S-curve
Total acceleration time = TACC + TSL
Total deceleration time = TDEC + TSL
The functions of parameters P1-34, P1-35 and P1-36 are each individual. When P1-
36 is set to 0 (Disabled), the settings of P1-34, P1-35 are still effective. It indicates
that the parameters P1-34 and P1-35 will not become disabled even when P1-36 is
disabled.
Please note:
1. When the source of speed command is analog command, the maximum setting
value of P1-36 is set to 0, the acceleration and deceleration function will be
disabled.
Analog Speed Command S-curve Filter
ASDA-B2 series servo drives also provide Analog Speed Command S-curve Filter for
the smoothing in response to a sudden analog input signal.

The analog speed command S-curve filter is for the smoothing of analog input signal
and its function is the same as the S-curve filter. The speed and acceleration curve of
analog speed command S-curve filter are both continuous. The above figure shows
the curve of analog speed command S-curve filter and the users can see the ramp of
speed command is different during acceleration and deceleration. Also, the users can
see the difference of input command tracking and can adjust time setting by using
parameter P1-34, P1-35, P1-36 to improve the actual motor performance according to
