Title Range Unit Function
2 07 B
3rd notch
frequency
50–5000 Hz
Notch frequency is automatically set to the 1st resonance frequency
estimated by the adaptive filter. In no re
sonance point is found, the
frequency is set to 5000.
2 08 B
3rd notch width
0–20 —
Automatically set when the adaptive filter is active.
2 09 B
3rd notch depth
0–99 —
Automatically set when the adaptive filter is active.
2 10 B
4th notch
frequency
50–5000 Hz
Notch frequency is automatically set to the 2nd resonance frequency
estimated by the adaptive filter. In no resonance point is found, the
frequency is set to 5000.
2 11 B
4rd notch width
0–20 —
Automatically set when 2 adaptive filters are active.
2 12 B
4rd notch depth
0–99 —
Automatically set when 2 adaptive filters are active.
*1) For parameter attribute, refer to Section 9-1.
4) How to Operate
Enter the action command with Pr2.00 (Adaptive filter mode setup) set to a value other than 0.
If the resonance point affects the motor velocity, parameters of 3rd notch filter and/or 4th notch filters are
automatically set according to the number of adaptive filters.
5) Other cautions
(1) Immediately after the first servo-on at start up; or after increasing stiffness setting with the real-time
auto-tuning enabled, abnormal sound or oscillation may be generated until the adaptive filter stabilizes. If
such abnormality lasts or repeats for 3 or more reciprocating operations, take the following
countermeasures.
1) Write the parameters which have given the normal operation into EEPROM.
2) Lower the setting value of Pr0.03 (Real-time auto-tuning machine stiffness setup).
3) Invalidate the adaptive filter by setting Pr2.00 (Adaptive filter mode setup) to 0.
4) Set up the notch filter manually.
(2) Abnormal sound or oscillation may excessively change the setup value of 3rd and 4th notch filters. If such
change occurs, disable the adaptive filter as described in step 3) above, change setup value of Pr 2.07 3rd
notch frequency and Pr 2.10 “4th notch frequency” to 5000 (disable), and then enable the adaptive filter
again.
(3) The 3rd filters (Pr 2.07) and 4th notch filters (Pr 2.10) are written to EEPROM every 30minutes. Upon
power up, these data are used as default values during adaptive process.
