 Tuning-less Rigidity Level
If you use tuning-less type 1 or 2 (Pn14F = n.0 or n.1), set the tuning-less level to
between 0 and 4 (Pn170 = n.0 to n.4). Do not set the tuning-less level to between
5 and 7 (Pn170 = n.5 to n.7).

Troubleshooting Alarms

An A.521 alarm (Autotuning Alarm) will occur if a resonant sound occurs or if excessive vibra-
tion occurs during position control. If an alarm occurs, implement the following measures.
• Resonant Sound
Decrease the setting of Pn170 = n.X or the setting of Pn170 = n.X.
• Excessive Vibration during Position Control
Increase the setting of Pn170 = n.X or decrease the setting of Pn170 = n.X.

Reset the tuning-less level to the default setting when removing the Servomotor from the
machine. The Servomotor may vibrate if the tuning-less level is not reset and the servo is turned
ON when the Servomotor has been removed from the machine.
