(As the load is lighter, tuning accuracy is higher.Tuning accuracy does not change even if the inertia is large.)· For the offline auto tuning, you can select either the motor non-rotation mode (Pr. 96 = "1") or rotation mode (Pr. 96= "101").· The rotation mode has higher tuning accuracy than the non-rotation mode.· Reading/writing/copy of motor constants tuned by offline auto tuning are enabled.· The offline auto tuning status can be monitored with the PU (FR-DU07/FR-PU07/FR-PU04).· Do not use an inverter with a surge voltage suppression filter (FR-ASF-H) connected between the inverter and motor.172
