Operation
4-7-11 Vibration Suppression when Stopping (Position)
■
When the Servo gain is increased, there may be vibration (such as the limit cycle) while stopped,
even though there is no vibration while moving. It was previously necessary to lower the response to
a gain where vibration while stopped subsided, sacrificing response during movement. To suppress
the vibration while movement is stopped, this function lowers the internal Servo gain only while
movement is stopped. Use this function by adjusting the parameters given below. After the vibration
suppression starting time (Pn421) has elapsed from the point where the position command is 0, the
internal Servo gain will change to the percentage set for the damping for vibration suppression on
stopping (Pn420).
■
Note Use when the damping for vibration suppression on stopping (Pn420) is 50% or higher, and the

vibration suppression starting time (Pn421) is 10 ms or longer. If a low value is set, the
response characteristics may be lowered and vibration may occur.
