Automatic Gain Adjustment Alarm and Handling Actions
When an error occurs in the automatic gain adjustment process, adjustments can be made through the
following counter-measures:
AL.003 Motor Overload
Cause Counter-measure
The system generates large
amplitude vibrations
Increase the load inertia ratio (Cn025) until the system can
operate steadily
AL.035 Tuning Failed
Cause Counter-measure
The System generates
Vibration Resonance or
Acoustic Resonance
Decrease the System Rigidity (Cn026) until the System can operate
steadily
Execute PC-Link Mechanical Characteristics Analysis Function
Observation to observe if resonance exists with the system and suppress it
