Leadshine DM556 Digital Stepper Motor Driver – 0.5A-5.6A

Built for high torque at high speeds, stepper drivers use current loop subdivision control to ensure very low motor torque ripple and very smooth operation to achieve the best positional accuracy. These clever modules, well, drive the stepper motors within your typical Maker machines, including 3D printers, CNC machines, and laser engravers, as well as a multitude of other mechanically driven devices. A great stepper motor driver impacts the overall quality of your machine’s output.

The Leadshine DM556 Stepper Motor Driver is a uniquely digital driver with auto-configuration and self-test technology. Based on a DSP with an advanced control algorithm, this motor driver is the next generation with level system smoothness, optimal torque, and wide motor compatibility. The digital features produce a higher microstep output for smooth performance, with resolutions from full step to 102,400 steps per revolution. Its adjustable output current of 0.5A to 5.6A is programmable for your purposes. The Leadshine DM556 Stepper Motor Driver is suitable for 2-phase or 4-phase motors, making it compatible with NEMA motors from 17 to 24. The optical isolation input signal allows for a pulse response frequency of up to 200 kHz. Strong anti-interference capability helps ensure the high precision positioning of your machine’s stepper motors.

The DM566 Stepper Motor Driver also comes with an automatic anti-overheating mechanism called a idle current reduction function, in which it reduces the current of the circuit by 50% when the motor hasn’t moved for 1 second. Additionally, it is recommended to leave about 20mm of space around the unit clear so as to ensure efficient heat dispersion and avoid heat-related problems.

The Leadshine DM556 Stepper Motor Driver is a useful digital motor driver, compatible with NEMA17 to NAME34 stepper motors and widely used in CNC machines and engravers.

DIP Pins SW1 to SW3: Current Settings Chart

Each different type of motor will have different current input requirements, which is why the SW1, SW2 and SW3 DIP switches are designed to adjust output current. When setting these, try to accommodate your motors’ requirements as closely as possible.

SW4: OFF = Half current, ON = Full current

Auto Tunning: SW4 changes 2 times in 1 second.

DIP Pins SW5 to SW8: Pulse/Rev Settings Chart

Pulse and revolution are set by SW5, SW6, SW7, and SW8 on the DM55 Stepper Motor Driver. The following chart shows all the options available and what settings SW5, SW6, SW7, and SW8 need to be in to achieve desired revolutions-per-minute.
