Precautions for Correct Use
 Adaptive filter may not operate correctly under the following conditions.
 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.
Refer to 11-7 Notch Filters on page 11-21 for information on notch filter.

Item Conditions that interfere with the adaptive filter
Resonance
points
• 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 there are three or more resonance points.
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.
