3 Utility Function Mode
3.2.31 Vibration Suppression Function (Fn205)
3-88
(1) Preparation
The following conditions must be met to perform the vibration suppression function.
The message “NO-OP” indicating that the settings are not appropriate will be dis-
played, if all of the following conditions are not met.
• The control must be set to position control.
• The tuning-less function must be disabled (Pn170.0 = 0).
• The test without a motor function must be disabled (Pn00C.0 = 0).
• The write prohibited setting (Fn010) must not be set to write-protect parameters.

Use the
or Key to move
through the list, select Fn205.
3
Press the Key. The display shown on
the left will appear.
Measure f: Measurement frequency
Setting f: Setting frequency [Factory-set to the
set value for Pn145]
If the setting frequency and actual operating
frequency are different, “Setting” will flash.
Note:
Frequency detection will not be performed if
there is no vibration or the vibration fre-
quency is outside the range of detectable fre-
quencies. The following screen will be
displayed if vibration is not detected. If the
vibration frequencies are not detected, prepare
a means of detecting and measuring the vibra-
tion. When the vibration frequencies are mea-
sured, go to step 5 and manually set the
measured vibration frequency to “Setting f.”
