Operation
Note 1. Make sure that the location of the decimal point is correct when setting the parameters.
Note 2. The Servo System loop gain will rise in response to a higher rigidity setting, shortening the

1.Increase the speed loop gain (Pn100) as much as possible without having the machinery vibrate,
2.Adjust the 1st step 1st torque command filter time constant (Pn401) and set it so there is no vibra-
3.Repeat steps 1 and 2, and return 10% to 20% from the changed values.
4.For position control, increase the position loop gain (Pn102) to the point where the machinery does
