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 notch filter or anti-resonance control set-
tings. 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.
Notes:
• If the vibration is great, the vibration frequency
will be detected even if the
and a notch filter or anti-resonance control will be
set.
• 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 linear servomo-
tor is stopped and no reference is input, this new
value will be effective, and the linear servomotor's
responsiveness 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 linear
servomotor does not stop approximately 10 sec-
onds after the FF level is changed, the setting is no
longer effective and will automatically return to the
previous setting.
• If the vibration is too small, the SERVOPACK may
not automatically detect the vibration frequencies.
