45A CANopen Servo Drive for High-Output Industrial Axes

45A CANopen Servo Drive for High-Output Industrial Axes

The MCAC845-23B-RC is a 45A CANopen Servo Drive delivering a 45 A output current from a 24-80 VDC supply over RS485+CANopen. Distributed by Lyenwsin, it guards the axis against overvoltage, undervoltage, overcurrent, position deviation, and disconnection faults. The drive provides a robust mid-to-high current node on a CANopen network.

Digital Loop Regulation

An ARM processor with a large programmable logic gate array (FPGA) executes the fully digital position, velocity, homing, and torque loops. Auto-tuning and resonance frequency identification reduce manual gain setting effort, letting the 45 A stage handle varying inertias without heavy commissioning on each new machine.

CANopen networking

RS485+CANopen offers a widespread, dependable factory fieldbus. Because the drive is addressable over the bus, parameters and live axis status are reachable from the master, simplifying integration into an existing multi-drop motion network without reconfiguring station wiring.

Feedback and Wiring

The drive supports both incremental and absolute encoders to suit different accuracy and cost needs. Rich I/O terminals provide limit switch, homing reference, and probe functions, with compatibility for PLCs from Inovance, Leadshine, Omron, Delta, and Beckhoff. Fault protection trips the axis to contain electrical and positional problems.

Key Specifications

Typical Applications

The drive fits factory automation, packaging machinery, robotics, inspection and semiconductor equipment, medical instrumentation, and printing lines where a 45 A CANopen servo axis must deliver protected output to a mid-to-high-current machine station. Contact Lyenwsin for datasheets, wiring guidance, and help selecting the right motor pair.

The RS485 and CANopen interfaces allow the drive to be addressed and monitored over the bus, so commissioning data and live status are available to the master. For machines that run close to continuous torque limits, the auto-tuning and resonance identification features help maintain stable operation across a range of load conditions.
