2.8A EtherCAT Linear Motor Drive - 220V Compact General Series (JALD4002-20B-EC)

Small 2.8A EtherCAT Linear Motor Drive

The JALD4002-20B-EC is a 2.8A EtherCAT Linear Motor Drive providing a 2.8 A output at 220 V in the JALD general series. Supplied by Lyenwsin, it targets smaller linear motor axes where space is limited but response still matters. The ARM+FPGA current loop maintains short settling time even at this current class.

Dynamic behavior

The optimized current loop and built-in disturbance observer keep the axis responsive and stable under varying load. Multiple control modes give the system integrator flexibility in how position and velocity loops are closed.

Commissioning path

microUSB covers local parameter setup, and remote FOE upgrades over Ethernet keep firmware current across a machine fleet with minimal downtime.

Key Specifications

• Supply voltage: 220 V
• Output current: 2.8 A
• Fieldbus: EtherCAT
• Control: ARM+FPGA, optimized current loop
• Disturbance observer: built-in
• Auto-tune: yes
• Multi-mode control: yes

Application Scenarios

Suitable for semiconductor equipment, precision positioning, inspection, CNC machine tools, battery manufacturing, and laboratory equipment. Typical roles are compact scanning stages, small die-handling axes, and automated sample stages where panel space is scarce.

Selection Considerations

Keep the axis within the current rating

2.8 A fits smaller linear motors. Verify the motor’s continuous current and confirm the 220 V supply can handle peak acceleration current without sagging.

Plan the upgrade path

Because firmware updates can be delivered over Ethernet, standardize on one firmware baseline across the fleet and schedule updates during planned downtime. Lyenwsin’s team can help with sizing and commissioning questions before you place the order.

On compact stages, the 2.8 A output is usually paired with small linear motors that move light carriages at high acceleration. The multi-mode control covers the positioning and velocity profiles these stages need, and the built-in disturbance observer keeps the loop stable when a sample or tool is loaded and unloaded during a production cycle. Because the drive is addressable over EtherCAT, several stages can be grouped under one master, keeping wiring and commissioning effort low on multi-axis tools.
