380V High-Voltage Servo Drive for CNC Machine Tools

The JASND55003-23B is a 380V High-Voltage Servo Drive built for demanding cycle duty on larger servomotors. Available through Lyenwsin, this flagship fieldbus drive operates on a 380 V three-phase supply and is rated for 12 A output, combining robust driving capability with fast response. It supports RS485, CANopen, EtherCAT, and ProfiNET so the machine can join whichever network the plant standardizes on.

High-Dynamics Control Loop

The ARM-plus-FPGA dual-chip platform splits supervisory and real-time tasks, letting the current loop execute quickly. Auto-gain tuning, multiple notch filters, and a disturbance torque observer work together to reject mechanical resonance and external disturbances while the axis is running, keeping motion smooth even under heavy cutting or handling loads.

Application Scenarios

This drive is specified for high-inertia cycle duty on larger servomotors:

• CNC machine tools: feed axes on milling and turning centers, where a 380 V plant supply is already standard and the axis must hold position under cutting load.
• Robotics: arm joints and high-inertia rotary axes on material-handling robots.
• Battery manufacturing: stacking, pressing, and high-cycle stations that index heavy tooling repeatedly.
• Packaging and material handling: large-format machines where servo torque must remain predictable through long cycles.

Selection Advice

Check the plant supply first

380 V drives require a three-phase industrial supply. Confirm the machine’s incoming voltage before specifying; the same axis can be ordered in a 220 V variant if the plant runs a low-voltage line.

Size the current to the servomotor

The 12 A output covers larger servomotors in high-inertia applications. Match the drive output to the motor’s rated and peak current rather than the drive maximum to preserve thermal margins.

Pick the fieldbus to fit the network

RS485, CANopen, EtherCAT, and ProfiNET options let the drive join the plant’s existing bus. Use the notch filters to remove known mechanical resonances before tuning the loop for production.
