45A EtherCAT Servo Drive with High Communication Efficiency

45A EtherCAT Servo Drive with High Communication Efficiency

The MCAC845-23B-EC is a 45A EtherCAT Servo Drive rated for 45 A output current from a 24-80 VDC supply over EtherCAT. Supplied by Lyenwsin, it is engineered for high communication efficiency and rich interfacing, with closed loop control at its core. Its design emphasizes low-latency network exchange and dependable multi-axis synchronization.

Topology and Control

An ARM processor with a large programmable logic gate array (FPGA) runs the fully digital position, velocity, homing, and torque loops. Auto-tuning and resonance frequency identification let the drive adapt to differing load dynamics. Because EtherCAT carries cyclic data efficiently, several drives can share one bus while each closes its own servo loop in real time.

closed loop operation over EtherCAT

closed loop regulation means encoder feedback governs the commanded motion, keeping the axis on target under load rather than accumulating step-based error. EtherCAT’s low-latency distribution of setpoints and feedback fits applications where multiple axes must stay tightly coordinated and where response to master commands is time-critical.

Feedback and Interfacing

The drive supports both incremental and absolute encoders, backed by rich I/O covering limit switch, homing reference, and probe functions. It interoperates with PLCs from Inovance, Leadshine, Omron, Delta, and Beckhoff. Built-in protection handles overvoltage, undervoltage, overcurrent, position deviation, and disconnection faults.

Key Specifications

• Output current: 45 A
• Supply voltage: 24-80 VDC
• Fieldbus: EtherCAT
• Communication: high communication efficiency, rich interfaces
• Control: closed loop; digital position, velocity, homing, torque
• Encoder support: incremental and absolute

Typical Applications

The drive maps to factory automation, packaging machinery, robotics, inspection and semiconductor equipment, medical instrumentation, and printing lines where a 45 A EtherCAT servo axis must combine closed loop accuracy with efficient network-level command of multiple axes. Lyenwsin can provide the matching motor and encoder set and help you commission the axis.

When integrating the drive, map the limit, homing, and probe signals to the rich I/O set before tuning so the axis can be referenced safely. The built-in protections cover electrical and position faults, keeping both the drive and the machine safe during production.
