5.6A 2-Phase Stepper Drive for 24-60 VDC Systems

5.6A 2-Phase Stepper Drive for 24-60 VDC Systems

The 2DM556 is a 5.6A 2-Phase Stepper Drive operating from a 24-60 VDC supply with a maximum output current of 5.6 A. The voltage window suits the common low-voltage DC buses used in compact machines, and the current rating provides margin for two-phase motors that draw between roughly 3 A and 5.6 A at rated torque.

Pulse Interfaces

Both Pulse/Dir and CW/CCW modes are supported, so the drive connects directly to step/direction outputs from PLCs, motion controllers, or dedicated CNC controls. In CW/CCW mode the host keeps rotation direction explicit, which simplifies commissioning on machines where wiring conventions vary between stations.

Low-Noise Operation

The drive is configured for low noise and low vibration. Smooth motion at moderate speeds is especially relevant on textile and printing lines, where a vibrating carriage can leave visible artifacts on the work piece or disturb downstream sensors.

Specifications

• Supply voltage: 24-60 VDC
• Maximum output current: 5.6 A
• Command modes: Pulse/Dir, CW/CCW
• Protection: overcurrent, overvoltage, undervoltage

Application Profile

The 2DM556 fits Industrial Automation, packaging machinery, compact CNC equipment, robotics, automated handling mechanisms, textile machinery, printing machinery, and food processing. It is a middle-range choice between the small 18-36 VDC drives and the high-voltage 8.4 A units, giving distributors a versatile option for mixed machine fleets.

Fault Protection

Overcurrent, overvoltage, and undervoltage protection guard the power stage. The overvoltage channel is particularly useful on 60 VDC buses where regeneration from a decelerating load can push rail voltage upward. Allow adequate airflow around the drive, and keep the motor cables away from high-voltage power lines to maintain clean step signals on longer cable runs. For a new design, size the DC supply with roughly 1.5 times the total continuous motor current so acceleration peaks do not drag the bus voltage below the drive’s operating window.
