RS485 CANopen Stepper Drive 2.2A - 2DM522-RC Compact Fieldbus Stepper Drive

A Small Stepper Drive for Existing Bus Networks

The 2DM522-RC is an RS485 CANopen Stepper Drive 2.2A delivering 0-2.2 A on a 24-48 VDC supply and communicating over RS485 and CANopen. Distributed by Lyenwsin, it is the practical choice when a small step axis must join an existing bus controller, particularly when converting a local relay or pulse system into networked motion.

Behavior at Low Current

Motor-control algorithms keep low-speed travel smooth and hold torque at higher step rates for this motor class. Customizable microstepping lets you match positioning resolution to the axis without changing the motor.

Configuration and wiring

Slave ID, baud rate, and direction are set from the keypad and digital display, and RJ45 keeps the cabinet wiring tidy. Protection covers phase loss, overcurrent, overvoltage, and disconnection.

Key Specifications

• Supply voltage: 24-48 VDC
• Output current: 0-2.2 A
• Fieldbus: RS485 + CANopen
• Digital inputs: 5
• Digital outputs: 2
• Microstepping: customizable
• Protection: phase loss, overcurrent, overvoltage, disconnection

Application Scenarios

Machines with several small axes and an existing RS485/CANopen backbone benefit most:

• Factory automation: bringing small legacy axes onto the network without replacing motors.
• Packaging machinery: feeders, diverters, and registration rollers driven from one controller.
• Compact CNC and robotics: tool changers, grippers, and auxiliary mechanisms.
• Textile, printing, and food processing: light repeatable axes in low-voltage cabinets.

Selection and Setup Advice

Confirm the motor current first

The 2.2 A output matches small NEMA motors. Check the motor nameplate before wiring, and keep the supply on a 24-48 VDC rail with adequate headroom for acceleration peaks.

Plan the I/O

Home, limit, and probe signals occupy the five inputs; brake, alarm, and in-position use the two outputs. Wire homing and limits before tuning so the axis can be referenced safely, and lean on Lyenwsin’s technical support if you are migrating an older relay panel.

The keypad and display confirm the network address and bus parameters before the first controlled move, so a single technician can bring the axis online in minutes.
