Theoperation time is increased for the specifiedtime.Enables smooth operation.The reference time increases by the filterdelay time even after the reference inputhas been completed.Enables smooth operation.The reference time increases by the filterdelay time even after the reference inputhas been completed.The feedback speed is smoother.The response is delayed if a large value isset.The speed reference is smoother.The response is delayed if a large value isset.These filters are effective in essentiallyall frequency bands.The response is delayed if a large value(low frequency) is set.Mainly effective for vibration between500 and 2,000 Hz.Instability will result if the setting is notcorrect.ReferenceSectionSpeed 8.5.4Position 8.6.4Position 8.6.4PositionSpeed9.4.7Speed 8.5.5PositionSpeedTorquePositionSpeedTorque9.4.109.4.109-4
