Adjust position controlproportional gain (C2-04).Turn OFF orientation signal (ORT).If a malfunction occurs during tuneup, reset the system, and then per-form the tuneup operation again.Tuneup completedTurn ON tuneup operation selection (Bit 4 of C2-22 turned ON).Adjust Control ConstantsAdjust Virtual Stop Position Offset (C2-13)S Perform adjustment so that final run-on is not delayed, and there is noovershooting.S If the load inertia changes, the characteristics will also change. Checkthe characteristics for the H, M, and L gears individually.Offset smallOffset largeStop position TimeAdjust Proportional Gain (C2-03)S If the ORE signal is not output close to the stop position, the gain willincrease.S Even if the ORE signal is output, if the shaft load is unsteady, the gainwill be reduced.Note: If there is no L gear selection in the machine specifications, omitthe following L gear adjustment procedure.Lit when M gear is selectedCheck L Gear SelectionInterface input status (U1-09)H Gear SelectionAdjust Proportional Gain (C2-02)S If the ORE signal is not output close to the stop position, the gain willincrease.S Even if the ORE signal is output, if the shaft load is unsteady, the gainwill be reduced.Check M Gear SelectionInterface input status (U1-09)Adjust Proportional Gain (C2-04)S If the ORE signal is not output close to the stop position, the gain willincrease.S Even if the ORE signal is output, if the shaft load is unsteady, the gainwill be reduced.Lit when L gear is selected8
