Adjustments
Set the machine’s vibration frequency in the parameter of a notch filter that is being used.
5.9.4 Position Integral Time Constant
This function adds an integral control operation to the position loop. It is effective for electronic cam or elec-
tronic shaft applications.

• Sufficient precautions must be taken when setting the notch filter frequencies. Do not
set the notch filter frequencies (Pn409 or Pn40C) that is close to the speed loop’s
response frequency. Set the frequencies at least four times higher than the speed
loop’s response frequency. (The Pn103 must be set correctly.) Setting the notch filter
frequency too close to the response frequency may cause vibration and damage the
machine.
• Change the notch filter frequency (Pn409 or Pn40C) only when the linear servomotor
is stopped. Vibration may occur if the notch filter frequency is changed when the lin-
ear servomotor is running.
