If readjustment is required, select the digit with the
or Key or change the FF LEVEL and FB
LEVEL with the
response.
Refer to 5.5.3 One-parameter Tuning Example for
details.
If readjustment is not required, go to step 9.
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.
<NOTE>
• 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 oper-
ation, vibration may occur because the responsive-
ness changes rapidly when the settings become
effective.
• The message "FF LEVEL" flashes until the SER-
VOPACK 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.
 If Vibration Occurs
• If vibration occurs, press the
VOPACK will automatically detect the vibration
frequencies and set the notch filters or anti-reso-
nance control. 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 row.
 If Vibration Is Large
• Even if the
PACK will automatically detect the vibration fre-
quencies and make notch filter or anti-resonance
control settings.
