3.2.32 Vibration Suppression (Fn205)
You can use this utility function to suppress transitional vibration at a low
frequency from 1 to 100 Hz, which is generated mainly when the
machine vibrates during positioning.
Vibration suppression is set automatically when advanced autotuning or
advanced autotuning with a reference input is executed. In most cases,
this utility function is not necessary. Use this utility function only if fine-
tuning is required or readjustment is required as a result of a failure to
detect vibration.
Perform one-parameter tuning (Fn203) if required to improve the
response after performing this utility function.
Preparations
Always check the following before you execute vibration suppression.
• The parameters must not be write-prohibited (Fn010 must be set to
0000).
• The servo must be in ready status.
• There must be no overtravel.
• Position control must be used.
• Tuning-less function must be disabled (Pn170 = n.
0).
• The test without a motor function must be disabled (Pn00C =
n.
0).
