AC Servomotors/Servo Drives 1S-series with Built-in EtherCAT® Communications User’s Manual (I586)
Precautions for Correct Use
• The adaptive notch filter may not operate properly under the following conditions.
• If the adaptive notch filter does not operate properly, disable it and manually set the notch fil-
ter. Refer to
on page 11-23 for information on notch filter.
1
Set
Adaptive Notch Filter
(3320 hex).
Select adaptive notch filter from 1 to 4 in
Adaptive Notch Filter - Adaptive Notch Selection
(3320-01 hex).
2
Start actual operation.
Enter an operation command and start the actual operation.
3
The notch filter is automatically set.
When the influence of resonance frequency appears in the motor speed, the selected notch fil-
ter is set automatically.
Precautions for Correct Use
• After startup, immediately after the first servo ON, unusual noise or vibration may occur until
the adaptive notch filter stabilizes. This is not an error 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.
• Write the value that are used during normal operation to the notch filter, and save the value
in the non-volatile memory.
• Disable the adaptive notch filter by setting
Adaptive Notch Selection
(3320-01 hex) to
0
.
• Manually set the notch filter.
• If unusual noise or vibration occurs, the setting of the notch filter selected in Adaptive Notch
Selection may be changed to an extreme value. In this case, disable Adaptive Notch Filter
and then disable the selected Notch Filter. Next, enable Adaptive Notch Filter again.
Item
Conditions that interfere with the adaptive filter
Resonance
frequency
• If the resonance frequency is 300 Hz or lower
• If the resonance peak or control gain is too low to affect the motor speed
• If more than one resonance frequency occurs
Load
• If the motor speed with high-frequency components changes due to backlash or other
non-linear elements
Command
pattern
• If the acceleration/deceleration is 3,000 r/min/s or higher
