Operation
pattern
• If the adaptive filter does not operate properly, use Notch 1 (3201 to 3203 hex) or Notch 2
(3204 to 3206 hex) to reduce resonance according to the manual adjustment procedure.

11-6-2 Objects Requiring Settings

Index Name
3200 hex Adaptive Filter Selection
G5 Series AC Servo Drives With Built-in EtherCAT Communications, Linear Motor Type
Position Control Mode, Speed Control Mode
• When Servo is ON.
• When elements other than control objects, such as the force limits, are set correctly and
there is no trouble with the motor's normal operation.
• Adaptive operation is disabled when magnetic pole position estimation is in progress.
Conditions that interfere with the adaptive filter
• If the resonance frequency is less than 3 times the response time frequency [Hz].
• If the resonance peak or control gain is too low to affect the motor speed.
• If there are three or more resonance points.
• If the motor speed with high-frequency components changes due to backlash or
other non-linear elements.
• If the acceleration/deceleration is 3,000 [mm/s] or higher.
Set the number of resonance frequencies to be estimated by
the adaptive filter and the operation to be performed after
estimation.
0: Adaptive filter disabled.
1: One adaptive filter enabled. The objects related to notch
filter 3 are automatically updated.
2: Two adaptive filters enabled. The objects related to notch
filters 3 and 4 are automatically updated.
3: Mode for measuring the resonance frequency. The
resonance frequency is measured. The measured result
can be checked using the support software. The
parameters related to notch filters 3 and 4 retain the current
values.
4: Adaptive result is cleared. Objects related to notch filters 3
and 4 are disabled and the adaptive result is cleared.
