If readjustment is required, select the digit with the
or Key or change the FF LEVEL and FB
LEVEL with the
response.
If readjustment is not required, go to step 10.
Note: The higher the FF LEVEL, the positioning time
will be shorter and the response will be better. If the
level is too high, however, overshooting or vibration
may occur. Overshooting will be reduced if the FB
LEVEL is increased.
If Vibration Occurs
• If vibration occurs, press the
VOPACK will automatically detect the vibration
frequencies and make notch filter or an anti-reso-
nance control settings. When the notch filter is set,
"NF1" and "NF2" are displayed on the bottom row.
When the anti-resonance control is set, "ARES"
will be displayed on the bottom low.

PACK will automatically detect the vibration fre-
quencies and make notch filter or anti-resonance
control settings.
Notes:
• If the FF LEVEL is changed when the servomotor
is in operation, it will not be reflected immediately.
The changes will be effective after the servomotor
comes to a stop with no reference input and then
the servomotor starts operation If the FF LEVEL is
changed too much during operation, vibration may
occur because the responsiveness is changed rap-
idly when the settings become effective.
• The message "FF LEVEL" flashes until the
machine reaches the effective FF LEVEL. If the
servomotor does not stop within approximately 10
seconds after changing the setting, a timeout will
occur. The setting will be returned to the previous
value.
