Check FF level and FB level settings with the tuning mode set to 2.
When the FB level is increased, the responsiveness will improve. As the FF level
increases, positioning time will be reduced. If the value is too large, however, vibration
will occur. SERVOPACK will detect vibration frequencies automatically and make notch
filter or anti-resonance control adjustment settings.

• A change in the FF level will become effective after the motor stops (i.e., the motor
comes to a stop with no reference input), and the response of the motor will change.
Wait until the set operation reference stops and check the response before adjusting the
FF level. If the FF level is changed greatly while the SERVOPACK is in operation, the
response will change radically. This may cause vibration.
• "FF LEVEL" will blink until the FF level is enabled. If the motor does not stop approx-
imately 10 seconds after the setting is changed, a timeout error will result and the pre-
vious setting will be enabled again.
• The vibration frequencies may not be detected if the amplitude is too small. If that
occurs, press the
