380 V Fieldbus Linear Motor Drive with EtherCAT

Flagship Fieldbus Linear Motor Drive for High-Voltage Plants

The JASNLD55003-23B-EC is a Fieldbus Linear Motor Drive rated on a 380 V supply with a 12 A output stage. Sourced through Lyenwsin, it sits in the flagship JASNLD series and is built to drive linear motors in semiconductor and precision-positioning machinery where feed current and bandwidth both matter.

EtherCAT motion and control modes

EtherCAT carries the cyclic position and velocity setpoints to the drive, supporting switchable control modes such as CSP, CSV, CST, PP, PV, PT, and HM. The latest PID tuning and auto-tune functions reduce commissioning effort when load inertia differs from initial assumptions.

Safety and feedback

An STO (safe torque off) input allows the drive hardware to cut torque safely without removing power from the common bus. A second encoder input supports external measuring feedback, useful on gantry and linear scale systems needing independent position verification.

Why a Dedicated Linear Motor Drive

Linear motors draw continuous current to hold position and demand fast current-loop response to produce smooth force. A drive built for rotary servos is often a compromise here; the JASNLD line is specified for the high feed current and stiffness that linear applications require.

Key Specifications

• Supply voltage: 380 V
• Output current: 12 A
• Fieldbus: EtherCAT
• Safety: STO
• Feedback: second encoder input
• Control modes: CSP, CSV, CST, PP, PV, PT, HM
• Commissioning: latest PID, auto-tune

Realistic Application Scenarios

The drive is used in semiconductor equipment, precision positioning, inspection, CNC machine tools, battery manufacturing, and laboratory equipment. Typical roles are linear stages on wafer handling, scanning axes in inspection tools, and gantry axes that must reject disturbance without losing position.

Selection Considerations

Verify the current budget

Before specifying, confirm the linear motor’s continuous and peak current demand against the 12 A output and check that the 380 V cabinet supply can support the peak. Lyenwsin’s engineers can review your motor datasheet with you.

Plan the safety and feedback wiring

Use the STO input where the machine safety circuit demands torque removal, and decide whether a second encoder or external scale is needed to meet the accuracy budget. Configurable I/O plus protections for overvoltage, undervoltage, overspeed, overload, position deviation, and encoder faults round out the package.
