How to Operate from the Console, By pressing

The motor starts rotating.

For approx. 15 sec, the motor repeats max. 5 cycles of CCW/CW rotation,

2 revolutions each direction per one cycle. Tuning may finish before 5th cycles, however, this is not an error.

How to Operate from the Console

(1)	Turn to the normal auto-gain tuning
	mode from the monitor mode, by
	pressing the SET button, then press
	the mode switching button three times.
	For details, refer to P.81, "Structure
	of Each Mode" of Preparation.
(2)	Enter the machine stiffness No. by pressing	.

Do not use the normal mode auto-gain tuning with the motor and driver alone. SV.Pr20 (Inertia ratio) becomes to 0.
