Mitsubishi Electric A1SD75M1 Positioning Unit Module

The Mitsubishi Electric A1SD75M1 Positioning Unit Module is a 1-axis motion controller for servo and stepper drives in MELSEC A Series PLC systems, designed to mount in a PLC rack as a dedicated positioning unit. It provides high-speed pulse output and point-table/positioning control to coordinate precise axis movement in CNC machines, packaging machinery, material handling lines, pick-and-place units, and assembly lines, delivering accurate, repeatable positioning with PLC-based motion programming. This module is intended for motion control upgrades, system expansion, or replacement of aging positioning units in industrial automation environments that require synchronized axis control. Common replacements include the A1SD75M2 Positioning Module, QD75M1 Positioning Module, and FX3U-20SSC-H Positioning Module.
