Caution
(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 “Selection of machine stiffness at real-time auto-gain
tuning”.
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 fre-
quency” to 5000 (disable), and then enable the adaptive filter again.
③
The 3rd filters (Pr 2.07 to Pr 2.09) and 4th notch filters (Pr 2.10 to Pr 2.12) are written to
EEPROM every 30minutes. Upon power up, these data are used as default values during
adaptive process.
