5-21 Torque Command Filter Time Constant
Function
Set the primary filter applied to the torque command. The 1st and 2nd filter is switched by gain
switching.
The torque command filter can suppress machine vibration that occurs when a servo loop is
configured.
Adjusting the time constant of the torque command filter may be able to suppress vibration.
Responsiveness worsens by increasing the time constant. Overshoots may occur as the servo
rigidity decreases. Depending on the machine, optimize the setting for this filter as well as the notch
filter explained in the next section.
