Control Gain And Filter Setting Parameters (P1.51~99) - Savch SDA2 Series User Manual

6.2 Control Gain and Filter Setting Parameters (P1.51~99)

◆The parameters with "*"indicate that they are enabled only when power on again after parameter setting.
P1.51 Moving average S-curve time
Setting range
P1.52 Low-pass filter (for S-curve) time constant
Setting range
P1.53 Command pulse smoothing function
Setting range
Filters can be added to commands for smoother follow-up.
This parameter is enabled under position control.
Specify the moving average S-curve filter time to position commands.
A larger setting at low command pulse frequencies or large electronic gear ratios can
Moving average reduce the torque ripple caused by fluctuation of the command pulse.
S-curve time
The new setting of this parameter is reflected when both the position command and filter
accumulation pulse are "0".
If P1.13 (tuning mode selection) is 10 (auto tuning), 11 (semi-auto tuning) or 15(shorter
cycle time operation mode) automatic adjustment is made inside the servo motor drive.
Enter the low-pass filter (for S-curve) filter time constant in relation to position commands
Low-pass filter (for
and speed commands.
S-curve) time
constant
Acceleration and deceleration are made so that an approximate S-curve is drawn.
The parameter is enabled under position control.
If the function is enabled, smoothing is added to the position command every 2 ms
intervals.
Command pulse
A larger setting at low command pulse frequencies or large electronic gear ratios can
smoothing function
reduce the torque ripple caused by fluctuation of the command pulse.
While the setting can be changed at any time, the new setting is reflected when both the
position command and filter accumulation pulse are "0".

P1.54 Position command response time constant
Setting range
Specify the following response characteristics to commands. A smaller setting improves the response
characteristics.
Automatic adjustment is made inside the amplifier if P1.13 (tuning mode selection) is 10 (auto-tuning), 11
(semi-auto tuning) or 15(shorter cycle time operation mode).
