Autotuning with a Host Reference

This section describes autotuning with a host reference.
Autotuning with a host reference makes adjustments based on the set speed loop gain (Pn100).
Therefore, precise adjustments cannot be made if there is vibration when adjustments are
started. Make adjustments after lowering the speed loop gain (Pn100) until vibration is eliminated.
