20A Fieldbus Linear Motor Drive - 220V EtherCAT Flagship for High-Acceleration Axes

Flagship 20A Fieldbus Linear Motor Drive

The JASNLD30002-23B-EC is the highest-current model in this JASNLD batch: a 220 V 20A Fieldbus Linear Motor Drive with a 20 A output stage. Supplied by Lyenwsin, it is built for linear motors on machines that draw substantial peak and continuous current, such as high-acceleration battery and CNC axes.

Control Modes and Loop Tuning

EtherCAT carries cyclic setpoints for multi-axis groups, and the drive switches among CSP, CSV, CST, PP, PV, PT, and HM modes to suit different motion profiles. Automatic tuning and the latest PID logic adjust the current loop for the connected load, cutting both setup time and settled error.

Application Scenarios

This drive is specified where a linear motor must deliver force quickly and hold position precisely:

• Battery manufacturing: high-acceleration stacking, winding, and tab-welding axes that index a cell or electrode thousands of times per shift.
• CNC machine tools: linear-motor feed axes on high-speed machining centers that need fast traverse and stiff positioning.
• Semiconductor equipment: wafer-handling and die-attach linear stages where position resolution decides yield.
• Inspection equipment and laboratory apparatus: scanning and positioning stages that settle quickly between measurements.

Selection and Safety Considerations

Supply and current sizing

The drive runs on a 220 V bus. Before specifying, confirm the linear motor’s continuous and peak current demands against the 20 A output, and check that the cabinet supply can support the peak without sagging.

Feedback planning

The second encoder input accepts an external linear scale, the standard way to hold accuracy where the machine is longer or stiffer than the motor’s own encoder can resolve.

Safety circuits

STO provides hardware-level safe torque off, so the drive can be integrated into the machine’s safety circuit without an external contactor in the power path. Protections cover overvoltage, undervoltage, overspeed, overload, position deviation, and encoder errors, and the internal disturbance observer and filters damp plant vibration.
