The adaptive filter function automatically specifies the following parameters.
Category
No.
Parameter
Setup
range
Unit Function
2 07 3rd Notch frequency 505000 Hz
Automatically specifies the first resonance frequency estimated by the
adaptive filter function.
If no resonance point is found, 5000 is specified.
2 08
3rd notch width
selection
020 -
This is automatically specified when adaptive filter is valid.
2 09
3rd notch depth
selection
099 -
This is automatically specified when adaptive filter is valid.
2 10 4th Notch frequency 505000 Hz
Automatically specifies the second resonance frequency estimated by
the adaptive filter function.
If no resonance point is found, 5000 is specified.
2 11
4th notch width
selection
020 -
This is automatically specified when two adaptive filters are valid.
2 12
4th notch depth
selection
099 -
This is automatically specified when two adaptive filters are valid.
4) Usage
Input an operating command with a value other than "0" specified for Pr2.00 "Adaptive filter mode
setup". If any effect of the resonance point is observed in the motor speed, the parameters for the third
and/or fourth notch filters are automatically specified according to the number of adaptive filters.
5) Other cautions
1) Abnormal noise or oscillation may be generated immediately after the first Servo On after power-up or af-
ter increasing the stiffness setting when real-time auto tuning is enabled until the load characteristics esti-
mation has been stabilized. This is normal if the condition is stabilized soon. If oscillation or continued
generation of abnormal noise through three or more reciprocating movements often occurs, take the fol-
lowing steps.
1) Write the parameters with which normal operation has been observed to the EEPROM.
2) Reduce value of Pr0.03 "Selection of machine stiffness at realtime auto-gain tuning"
3) Specify "0" for Pr2.00 "Adaptive filter mode setup" and make adaptive invalid.
4) Manually specify the notch filters.
2) After any abnormal noise or oscillation has occurred, the third and fourth notch filter settings may be
modified to an extreme value. In that case, make adaptive filter invalid by the procedures of 3) above and
specify a setting value "5000" (Invalid) for Pr2.07 "3rd notch frequency" and Pr2.10 "4th notch frequency."
Then make the adaptive filter valid again.
3) 3rd notch frequency (Pr2.07) and 4th notch frequency (Pr2.10) are written in EEPROM every 30 minutes.
The data are used as the initial values for adaptive processing at the next power-up.
