Display after Operation Keys
Input an external /S-ON signal. The display will
change from "BB" to "RUN." Input a reference from
the host controller.
The set value will be displayed. Press the
after checking the value.
Mode 2 or 3 is used to make level adjustments. When
the level is increased, the responsiveness will
improve. If the value is too large, however, vibration
will occur. If that occurs, press the
SERVOPACK will detect the vibration frequencies
automatically and make notch filter or anti-resonance
control settings.
If the vibration is great, the vibration frequency will
be detected even if the
notch filter or anti-resonance control will be set.
The positioning time will become shorter if the FF
level is increased. If the FF level is too high, over-
shooting will result. Adjust FF level and FB level
with the ,
Key.
Note:
• A change in the FF level will become effective
after the motor stops (i.e., the motor comes to a
stop with no reference input), and the response of
the motor will change. Wait until the set operation
reference stops and check the response before
adjusting the FF level. If the FF level is changed
greatly while the SERVOPACK is in operation, the
response will change radically. This may cause
vibration.
• "FF LEVEL" will blink until the FF level is
enabled. If the motor does not stop approximately
10 seconds after the setting is changed, a timeout
error will result and the previous setting will be
enabled again.
A confirmation screen is displayed after adjustment.
Press the
ten to the SERVOPACK, "DONE" will blink for two
seconds.
