Note:If a setting is made for calculating the moment of inertia, the mode switch function will be disabled while the
moment of inertia is being calculated. At that time, PI control will be used. The mode switch function will be
enabled after calculating the moment of inertia.
• Speed feedforward or torque feedforward is input.
• The positioning completed width (Pn522) is too small.
Change only the overshoot detection level (Pn561) to finely adjust the amount of overshooting without chang-
ing the positioning completed width (Pn522). Because Pn561 is set by default to 100%, the allowable amount
of overshooting is the same amount as that for the positioning completed width.
When Pn561 is set to 0%, the amount of overshooting can be adjusted to prevent overshooting the positioning
completed width. If the setting of Pn561 is changed, however, the positioning time may be extended.

Applicable servomotor : SGMJV- A
Mode selection: Fixed to Mode 1 (Mode = 1) and cannot be changed.
• Advanced autotuning makes adjustments by referring to the positioning completed
width (Pn522). If the SERVOPACK is operated in position control (Pn000.1=1), set the
electronic gear ratio (Pn20E/Pn210) and positioning completed width (Pn522) to the
actual value during operation. If the SERVOPACK is operated in speed control
(Pn000.1=0), set Mode to 1 to perform advanced autotuning.
• Unless the positioning completed signal (/COIN) is turned ON within approximately 3
seconds after positioning has been completed, "WAITING" will flash. Furthermore,
unless the positioning completed signal (/COIN) is turned ON within approximately 10
seconds, "Error" will flash for 2 seconds and tuning will be aborted.
