P1 - 36 TSL
Accel /Decel S-curve Communication Addr.: 0124H
Default: 0 Applicable Control Mode: P/S
Range: 0~10000 (0: disabled)
Unit: msec
Note: If the setting value of parameter P1-36 is set to 0, it indicates Accel / Decel S-curve function is
disabled and the command is just By-Pass.
Analog Input Filter
ASDA-A series AC drive also provide analog input filter for the smoothing in response to a sudden analog
input signal.

Analog speed command
The analog input 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 input filter are both continuous. The above figure shows
the curve of analog input filter and you can see the ramp of speed command is different during acceleration
and deceleration. Also, you can see the difference of input command tracking. Users can adjust time setting
by using parameter P1-34, P1-35, P1-36 to improve the curve according to actual condition.
Input Command Low-pass Filter
Command (Input) Low-pass Filter is used to eliminate the high frequency response and interference or noise
and it is with smoothing function.
Relevant parameters:
P1 - 06 SFLT
Accel / Decel Smooth Constant of Analog Speed
Command (Low-pass filter)
Communication Addr.: 0106H
Default: 0 Applicable Control Mode: S
Range: 0~1000 (0: Disabled)
Unit: msec
Note: If the setting value of parameter P1-06 is set to 0, it indicates the function of this parameter is
disabled and the command is just By-Pass.
