JUSP-SL2H is Yaskawa E-LINK II sensor hub expansion module matched with Sigma II SGDH servo amplifiers. It collects external linear encoder signals to realize full closed-loop high-precision positioning with stable differential signal transmission.

JUSP: General servo accessory module prefix;SL: E-LINK II linear encoder sensor hub series;2: Second-generation E-LINK communication specification;H: Standard hardware version without customized signal pins.

Control power supplied by matched SGDH servo drive, power consumption 2W. Supports high-resolution linear scale differential input, communication speed up to 4Mbps. Operating temperature 0–55℃, storage temperature -20–85℃, protection grade IP10, anti-electromagnetic interference design for industrial workshop environment.

CN10 bus connector plugs into the side port of SGDH servo amplifier for E-LINK II data interaction. Dedicated linear encoder input terminal receives differential position feedback signals from external grating ruler. Built-in signal processing circuit converts position data and transmits to servo drive via high-speed serial bus. LED indicators display communication running state and fault alarm.

Realizes full closed-loop control by collecting linear encoder position signals, eliminating mechanical lead screw error. Supports real-time position data latch function for precise origin detection. Built-in communication error and signal disconnection protection logic. Automatically matches servo parameters after power-on, reducing manual setting steps, compatible with multi-axis synchronous positioning.

Applied to precision automation equipment requiring micron-level positioning accuracy, including precision engraving machines, high-precision testing platforms, semiconductor micro assembly equipment, laser processing machinery and precision cutting equipment with linear grating feedback.

Cut off the main power of servo drive before plugging or unplugging the module, wait 10 minutes for internal capacitance discharge. Avoid strong vibration and oil mist corrosion at the installation position. Regularly check encoder wiring terminals for loose contact or signal line aging. Clean module surface dust every three months. Replace damaged differential signal cables immediately when communication failure alarms occur.
