Fine Tuning

[Step 3. Gain adjustment]
Adjust the parameters to optimum values at the servo amplifier while running the motor.
(6) Set the adjustment indicator.

Emphasis on command response/emphasis on disturbance response
Select whether to perform adjustment emphasizing the response to commands to the servo
amplifier, or adjustment emphasizing the response to disturbances.
* By placing emphasis on command response, settling time will be shorter, however, the
response to disturbances will drop.
If placing emphasis on disturbance response, the response to disturbances will increase,
however, settling time will be longer.

Stability level
Select the margin for the maximum setting range for the control gain calculated from
frequency characteristics.
The greater the value, the greater the margin (stability), however, the response will drop.
(7) Set the operation profile. (Forward/reverse rotation is repeated based on the set gain.)
(8) Press the adjustment "START" button to begin operation and gain adjustment.
(9) The adjustment results for gain and filter settings are displayed.
(10) If there are no problems with the adjustment values at (9), press the [Write Adjustment
Results] button to complete adjustment.
If unsatisfied with operation based on the adjustment values at (9), reset the adjustment
indicator at (6), and perform adjustment again.
