The UM1LG3-310B-1AA-1SA-Z is a high-precision direct-drive linear servo actuator / drive module (LINEARSERV series) from Yokogawa. It combines servo motor + linear actuator (slider) plus head amp / drive in an integrated unit. Designed for applications demanding excellent position accuracy, minimal backlash, and high dynamic performance (motion control, semiconductor equipment, precision assembly, etc.). The suffixes indicate feedback/encoder type (“1AA-1SA”) and connector/option/version (“Z”).
