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.
