RS485 CANopen 5.6A Stepper Drive

RS485 CANopen 5.6A Stepper Drive for Mixed Networks

The 2DM556-RC is an RS485 CANopen 5.6A Stepper Drive operating on 24-48 VDC with a 0-5.6 A output and support for RS485 and CANopen. Offered through Lyenwsin, it is a practical option when a step axis must join an existing bus-based controller that is not EtherCAT-native.

Motion Behavior and Microstepping

Advanced algorithms yield smooth low-speed travel and retain torque at high step rates. Customizable microstepping balances resolution against velocity, letting the same drive cover both fine-index and fast-feed duties without changing the motor.

I/O, wiring, and servicing

Five inputs accept home, limit, and probe signals; two outputs drive brake, alarm, and in-position functions. RJ45 connectors and a keypad/display round out commissioning, with slave ID, baud rate, and direction set locally.

Key Specifications

• Supply voltage: 24-48 VDC
• Output current: 0-5.6 A
• Fieldbus: RS485 + CANopen
• Digital inputs: 5
• Digital outputs: 2
• Microstepping: customizable
• Protection: phase loss, overcurrent, overvoltage, disconnection

Application Scenarios

Used in factory automation, packaging, compact CNC, robotics, automated handling, textile, printing, and food processing. Common deployments include converting legacy relay-driven step axes to networked motion and adding slave axes to a CANopen line that already has a master.

Retrofit and Selection Notes

Reuse the installed motor

Because the drive communicates over RS485 and CANopen, the existing step motor and mechanics can usually stay in place. Verify the motor’s current rating is within the 5.6 A output and confirm the supply rail is 24-48 VDC before commissioning.

Commissioning order

Wire home, limit, and probe inputs first so the axis can be referenced safely, then set node ID and baud rate on the keypad. Lyenwsin ships the drive with clear documentation and offers technical support to keep retrofit projects on schedule.

The five inputs and two outputs cover the signals a typical step axis needs, which keeps the drive self-contained on retrofit machines. Because the fieldbus and the power stage are independent, the same drive can be configured for either RS485 or CANopen operation, giving plant engineers flexibility when a line migrates between protocols.
