To Next PageTo Next PageWhat to do if YASKAWA Servo Drives show A.521 Autotuning Alarm during position control?
If you encounter an A.521 alarm (Autotuning Alarm) due to resonant sound or excessive vibration during position control with YASKAWA Servo Drives, try the following: * Decrease the setting of Pn170 = n.X??? or the setting of Pn170 = n.?X??. * Alternatively, increase the setting of Pn170 = n.X??? or decrease the setting of Pn170 = n.?X??.
