5.5 Fine Tuning

5.5.1 What is Fine Tuning?

If unsatisfied with operation using "easy tuning" or "auto tuning" adjustments, adjustments can be made
using the "fine tuning" function.
The status of the motor run with the servo amplifier is observed with PC Loader, and this function is
used to set optimum control gain and filter setting values based on the operating status.
* PC Loader is required to use this function.
