1
Set the Adaptive Filter Selection (3200 hex).
Select adaptive filter 1 or 2 in the Adaptive Filter Selection (3200 hex).
2
Start actual operation.
Enter an operation command and start the actual operation.
3
The Notch Filters 3 and 4 are automatically set.
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 UsePrecautions for Correct Use
• An unusual noise or vibration may occur until the adaptive filter stabilizes after startup,
immediately after the first servo ON, or when the Realtime Autotuning Machine Rigidity
Selection (3003 hex) is increased. This is not a problem if it disappears right away. If the
vibration or unusual noise, however, continues for three or more reciprocating operations, take
the following measures in the possible order.
• 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.
(Resetting of inertial estimation and adaptive operation)
• 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, set Adaptive Filter Selection
(3200 hex) to 0 to disable the object and 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.
