6. GENERAL GAIN ADJUSTMENT
6.2.3 Adjustment procedure by auto tuning
Since auto tuning is made valid before s hipment from the factory, simply running th e servo motor automatically
sets the optimum gains that match the m achine. Merely changing the response level sett ing value as required
completes the adjustment. The adjustment procedure is as follows.
