pensation is too low, however, the response waveform will vibrate.
6. Find the condition in which the shortest setting time is obtainable within the
range where the position error or torque reference waveform observed through
the analog monitor is not vibrating or unstable.
7. The servo gain adjustment is completed when no further shortening of the posi-
tioning time is possible.
• Speed feedback compensation usually makes it possible to increase the speed loop gain and position loop gain. The
machinery may vibrate excessively if the compensation value greatly changes or Pn110.1 is set to "1" (i.e., speed feed-
back compensation disabled) after increasing the speed loop gain or position loop gain.
