The higher the level, the greater the responsiveness
will be. If the value is too large, however, vibration
will occur.
If that occurs, press the
will automatically detect the vibration frequencies
and make the notch filter or anti-resonance control
settings. When the notch filter is set, "NF1" or "NF2"
will be displayed on the bottom row.
When the anti-resonance control is set, "ARES" is
displayed on the bottom row.
Notes:
• If the vibration is great, the vibration frequency
will be detected even if the

• If the vibration is too small, the SERVOPACK may
not automatically detect the vibration frequencies.
If so, press the
tion.
• The higher the FF level, the shorter the positioning
time will be. If the level is too high, however, over-
shooting will occur.
• If the FF level is changed when the servomotor is
stopped and no reference is input, this new value
will be effective, and the servomotor's responsive-
ness will be changed. To safely adjust the FF level,
wait until all operations have been completed and
check the responsiveness. When the FF level is
changed largely, vibration may occur because the
responsiveness is changed rapidly.
• The message, "FF LEVEL", blinks until the
machine reaches the effective FF level. If the ser-
vomotor does not stop approximately 10 seconds
after the FF level is changed, the setting is no
longer effective and will automatically return to the
previous setting.
