(3) Detection of Vibration Frequencies
Frequency detection may not be possible if there is not enough vibration to affect the position error.
The detection sensitivity can be adjusted by changing the setting for the remained vibration detection width
(Pn560) which is set as a percentage of the positioning completed width (Pn522). Perform the detection of
vibration frequencies again after adjusting the remained vibration detection width (Pn560).
Note: As a guideline, change the setting 10% at a time. The smaller the set value is, the higher the detection sensitivity will
be. If the value is too small, however, the vibration may not be detected accurately.
The vibration frequencies that are automatically detected may vary somewhat with each positioning operation.
Perform positioning several times and make adjustments while checking the effect of vibration suppression.

Vibration Suppression Function Operating Procedure
The following procedure is used for vibration suppression function.
Vibration suppression function is performed from the digital operator (option) or S.
The operating procedure from the digital operator is described here.
Refer to the
Σ
-V Series User’s Manual, Operation of Digital Operator
(No.: SIEP S800000 55) for basic key
operations of the digital operator.
Note: If this function is aborted by pressing the MODE/SET Key, the SERVOPACK will continue operating until the ser-
vomotor comes to a stop. After the servomotor stops, the set value will return to the previous value.
The operating flow of the vibration suppression function is shown below.
