10-6 Adaptive Filter

Operating Procedure

1. Set the Adaptive Filter Selection (Pn200).
Select an adaptive filter from 1 to 4 on the Adaptive Filter Selection (Pn200).
2. Start an 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 resonance point appears in the motor speed, the parameters for the
Notch Filters 3 and 4 are set automatically in accordance with the number of adaptive filters.
 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
(Pn003) is increased, but 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.
 If unusual noise or vibration occurred, the setting of Notch 3 (Pn207 to Pn209) or Notch 4 (Pn210
to Pn212) may have changed to an extreme value. In this case, set Adaptive Filter Selection
(Pn200) to 0 to disable the parameter and then set Notch 3 Frequency Setting (Pn207) and Notch
4 Frequency Setting (Pn210) to 5,000 (disabled). Next, enable Adaptive Filter Selection again.
 Notch 3 Frequency Setting (Pn207) and Notch 4 Frequency Setting (Pn210) 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.

Precautions for Correct Use
• Write the parameters used during normal operation to the EEPROM.
• Lower the Realtime Autotuning Machine Rigidity Selection (Pn003).
• Disable the adaptive filter by setting the Adaptive Filter Selection (Pn200) to 0.
(Resetting of inertial estimation and adaptive operation)
• Manually set the notch filter.
