748 748  Low-frequency vibration suppression is suitable for working conditions where the motor vibrates during deceleration and shutdown after the position command is sent, and the vibration amplitude gradually decreases. The use of the low-frequency vibration suppression function is effective in reducing the time to complete positioning due to vibration effects.

For example, when the vibration amplitude is greater than (P5-12*P4-14*0.001) detection amplitude ratio. For example, in P05-12=800, P04_14=50, the vibration amplitude is greater than P5-12*P4-14*0.001=800*50*0.001=40 pulses, stop vibration frequency can be identified in U0-16.
