Auto-Gain Tuning Mode

Normal Mode Auto-Gain Tuning Screen

<Remarks>

•For details of normal auto-gain tuning, refer to P.148, "Normal Auto-Gain Tuning" of Adjustment. Pay a special attention to applicable range and cautions.

•The motor will be driven in a preset pattern by the driver in normal auto-gain tuning mode.You can change this pattern with SV.Pr25 (Normal auto tuning motion setup), however, shift the load to where the operation in this pattern may not cause any trouble, then execute this tuning.

•Depending on the load, oscillation may occur after the tuning. In order to secure the safety, use the protective functions of SV.Pr26 (Software limit set up), SV.Pr70 (Position deviation error level) or SV.Pr73 (Overspeed level).

<Remarks>
Don't disconnect the console from the driver between				and		.

Should the connector is pulled out, insert it again and repeat the procedures from the beginning. <Note> If the following status occurs during the tuning action, the tuning error occurs.

(1) During the tuning action, 1) when an error occurs, 2) when turned to Servo-OFF,

3) even the deviation counter is cleared and 4) when the tuning is actuated close to the limit switch.

(2)When the output torque is saturated because the inertia or load is too large.

(3)When the tuning can not be executed well causing oscillation.

If the tuning error occurs, value of each gain returns to the previous value before the tuning. The driver does not trip except error occurrence. Depending on the load, the driver might oscillate without

becoming tuning error. (not showing ) Extra attention should be paid to secure the safety.
