11-6-4 Operating Procedure

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 it falls in a stable state 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) objects to 5000 (disabled). After that,
enable the 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.

The resonance frequency 2 that is assumed by the adaptive
filter is automatically set.
If no resonance point is found, the value 5000 is set.
When two adaptive filters are enabled, this object is set
automatically.
When two adaptive filters are enabled, this object is set
automatically.
