6A Fieldbus Linear Motor Drive - 380V EtherCAT Flagship with STO (JASNLD30003-23B-EC)

6A Fieldbus Linear Motor Drive for Precision Linear Motion

The JASNLD30003-23B-EC is a 6A Fieldbus Linear Motor Drive delivering a 6.0 A output from a 380 V supply in the JASNLD flagship series. Available through Lyenwsin, it is sized for linear motors in inspection and precision-positioning machines that need continuous force from a well-regulated feed current.

EtherCAT control architecture

EtherCAT synchronizes the cyclic setpoints for deterministic multi-axis behavior. Switchable control modes (CSP, CSV, CST, PP, PV, PT, HM) and auto-tune let the drive adapt to the mechanical system, shortening settling time on high-bandwidth axes.

Safety and external feedback

STO removes torque safely at the hardware level, and the second encoder input handles external scales or a second position reference. Built-in filters and a disturbance observer suppress vibration and load steps that would otherwise degrade positioning.

Where the 6 A Class Fits

Configured I/O supports machine-level signaling. Applications span semiconductor equipment, precision positioning, inspection, CNC machine tools, battery manufacturing, and laboratory equipment, with the 6 A rating matching moderate-force linear stages that still require clean, regulated current.

Selection and Commissioning Notes

Confirm the force requirement

6 A covers moderate-force linear motors. Verify the motor’s continuous and peak current against the output stage before finalizing the bill of materials, and leave headroom for acceleration peaks.

Use auto-tune early

Run the auto-tune procedure after the stage is mechanically assembled so the loop locks onto the real inertia and stiffness. Lyenwsin provides commissioning documentation and remote technical support to keep the startup short.

The switchable control modes cover position, velocity, and torque profiling, so the same drive can run both point-to-point moves and continuous-path interpolation on a gantry or inspection axis. This flexibility, combined with the second encoder input, lets machine builders standardize on one drive type across a family of precision stages.
