Keys
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 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.
 If Vibration Occurs
• If vibration occurs, press the
winding drive unit will automatically detect the
vibration frequencies and make notch filter or an
anti-resonance control settings. When the notch fil-
ter 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.
 If Vibration Is Large
• Even if the
ing drive unit will automatically detect the vibra-
tion frequencies 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.
