To reduce the noise, resolution must be increased. Bus resolution has to be manually set from PAC program (bus scaling factor for position (0x2021.2 and 0x2021.11). A good value is 2^16 (16 bit = y4 scaling of 48). The resolutions in the pull-down menus in the ds402 scaling aren't high enough for smooth motion for linear servo motors (max is 10^9 for version 9-70).
