Set Automatically
The adaptive filter function sets the following objects automatically.
1
Select adaptive filter 1 or 2 in the Adaptive Filter Selection (3200 hex).
2
Enter an operation command and start the actual operation.
3
When the influence of a resonance point appears in the motor speed, the notch filters 3
and 4 objects are set automatically according to the number of adaptive filters.
Precautions for Correct Use Precautions for Correct Use
• An unusual noise or vibration may occur until load characteristic estimation is stabilized after
startup, immediately after the first servo ON, or when the Realtime Autotuning Machine
Rigidity Setting (3003 hex) is increased.
This is not a problem if the noise or vibration disappears right away. If vibration occurs, or if an
unusual noise lasts for three or more reciprocating operations, however, take the following
measures.
• Write the objects used during normal operation to the EEPROM.
• Lower the Realtime Autotuning Machine Rigidity Setting (3003 hex).
• Disable the adaptive filter by setting the Adaptive Filter Selection (3200 hex) to 0.
• Manually set the notch filter.
• If unusual noise or vibration occurs, the setting of Notch 3 (3207 to 3209 hex) or Notch 4 (3210
to 3212 hex) may have changed to an extreme value. In this case, first of all, set the Adaptive
Filter Selection (3200 hex) to 0 to disable the object. Then, set the Notch 3 Frequency Setting
(3207 hex) and Notch 4 Frequency Setting (3210 hex) to 5,000 (disabled). Next, enable
Adaptive Filter Selection again.
• The Notch 3 Frequency Setting (3207 hex) and Notch 4 Frequency Setting (3210 hex) are
written to the EEPROM every 30 minutes. When the power supply is turned OFF and then
turned ON again, this data is used as the default settings to perform adaptive operation.
11-6-3 Objects to Be Set Automatically
Index Name Description
3207 hex Notch 3 Frequency Setting The resonance frequency 1 that is assumed by the adaptive filter is
automatically set.
If no resonance point is found, the value 5,000 is set.
3208 hex Notch 3 Width Setting When the adaptive filter is enabled, this object is set automatically.
3209 hex Notch 3 Depth Setting When the adaptive filter is enabled, this object is set automatically.
3210 hex Notch 4 Frequency Setting The resonance frequency 2 that is assumed by the adaptive filter is
automatically set.
If no resonance point is found, the value 5,000 is set.
3211 hex Notch 4 Width Setting When two adaptive filters are enabled, this object is set
automatically.
3212 hex Notch 4 Depth Setting When two adaptive filters are enabled, this object is set
automatically.
