5-44
4
In this measurement results example, the positioning
time has decreased over the previous time, but over-
shooting has occurred.
Measure the positioning time with a measuring instru-
ment.
If the measurement results and specifications are met,
this concludes the tuning. Go to step 8.
Go to the next step if overshooting occurs before the
specifications are met.
5
First input the reference from the host controller, then
increase the FB LEVEL with the digital operator to
reduce overshooting.
<NOTE>
• Move the digit with the or Key and
increase or decrease the value with the or
Key.
6
Measure the positioning time with a measuring instru-
ment.
If the measurement results and specifications are met,
this concludes the tuning. Go to step 8.
Go back to step 3 if overshooting occurs before the
specifications are met.
Go to the next step if vibrations occur before over-
shooting stops.
7
Press the Key on the digital operator.
The SERVOPACK will automatically detect the vibra-
tion frequencies and set the notch filters or an anti-res-
onance control. When a notch filter is set, “NF1” or
“NF2” is displayed on the bottom row of the digital
operator. When anti-resonance control is set, “ARES”
is displayed on the bottom row of the digital operator.
<NOTE>
If the vibration is large, a notch filter or anti-resonance
control will be automatically set even if the Key
is not pressed.
After making the setting, go back to step 6.
8
Press the Key. A confirmation screen will be dis-
played after tuning.
9
Press the Key. The tuning results data will be
saved in the SERVOPACK.
When the data has been saved, “DONE” will flash for
two seconds, and then “RUN” will be displayed.
<NOTE>
• Press the Key to cancel saving the data.
• Press the Key to readjust the FF LEVEL and
FB LEVEL without saving the data.
