8.2.2 Tuning-less Levels Setting Procedure
8-18
4.
For 3rd digit, select one of the load levels in the Tuning-less Load Level list.
• If the response waveform results in overshooting or if the load moment of inertia exceeds the allowable
level, select 2: Tuning-less Load Level 2. (If any damage caused when the load moment of inertia
exceeds the allowable level, these conditions are regarded as being outside the scope of the warranty.)
• If a high-frequency noise is heard, select 0: Tuning-less Load Level 0
5.
For 2nd digit, select one of the tuning-less levels in the Tuning-less Level list.
The higher the value of the level is, the higher the gain will be. A higher gain means better response.
Note 1. If the tuning-less level is too high, vibration might occur. Lower the level if vibration occurs.
2. If the tuning-less level is changed, the automatically set notch filter will be canceled (disabled). If any
vibration occurs, the notch filter will automatically be set again.
6.
Click OK.
7.
To enable the change in the setting, restart the SERVOPACK.
(3) Alarm and Corrective Actions
The autotuning alarm (A.521) will occur if resonance sound is generated or excessive vibration occurs during
position control. If that occurs, increase the setting of parameter Pn170.3 or decrease the setting of parameter
Pn170.2.
