2.8A CANopen closed loop Stepper Drive for 24VDC Cells

Compact closed loop Drive With RS485 and CANopen

The 2.8A CANopen closed loop Stepper Drive 2HCS528-RC pairs RS485 and CANopen with a 24 VDC supply and 2.8 A output. Running a power-angle closed loop algorithm on a 32-bit ARM core, it keeps torque present at medium and high speeds while staying light enough for small automation cells. This makes it well matched to the modest current demands of compact motion axes.

Close the Loop on Smaller Motors

Protection Against Missed Steps

Because it reads rotor position and corrects excitation in real time, the 2HCS528-RC protects smaller steppers from missed-step excursions during acceleration. The trade-off is a current stage scaled to 2.8 A, so the drive should be paired with motors within that envelope.

Compact Thermal Profile

The low current keeps heat generation modest, which is valuable in enclosed panels where several drives share limited ventilation.

RS485 and CANopen Selection

Both physical layers are available, letting the integrator pick the bus already present in the cabinet. CANopen suits noisy industrial floors; RS485 suits direct controller links.

Interface and Configuration

The keypad and digital tube display configure slave ID, baud rate, and rotation direction on-site, supported by a defined digital I/O set.

• Supply 24 VDC, output current 0-2.8 A
• RS485 and CANopen fieldbus
• 5 digital inputs for homing, limits, and probe
• 3 digital signals for brake, alarm, and in-position

Where to Use

Applications span factory automation, packaging machinery, compact CNC equipment, robotics, automated handling mechanisms, textile machinery, printing machinery, and food processing. For a small cell running 24 VDC with CANopen, this drive is a lean closed loop addition.

Operational Planning

Keep the supply wiring short and rated for the 2.8 A peak so the small drive sees a stable rail during acceleration. On a CANopen bus, verify node addressing and baud rate before the first production run, and use the three digital signals to give the PLC a complete picture of axis state.

Distributor Support

Lyenwsin supplies the 2.8A CANopen closed loop Stepper Drive with current-class matching and bus configuration help, so the drive is sized correctly for its compact application.
