Current Setting: First, adjust the driver's output current according to the stepper motor's rated current. This is usually done via a DIP switch or potentiometer, ensuring the current matches the motor to avoid overheating or insufficient drive force. For example, if the motor's rated current is 2A, the driver should be set to the same or slightly lower value (e.g., 1.8-2A).
Microstepping Setting: Microstepping determines the precision of each step. Common microstepping settings include 1/2, 1/4, 1/8, and 1/16. Higher microstepping improves motion smoothness but reduces maximum speed. For example, for applications requiring high precision (such as 3D printers), a 1/16 microstepping setting is recommended; while for speed-priority applications (such as conveyor belts), 1/4 or 1/8 microstepping can be selected.
Direction and Enable Signal Settings: Connect the driver to the controller via the DIR (direction) and EN (enable) signal interfaces.
The DIR signal determines the motor's rotation direction, and the EN signal enables or disables the motor. Ensure correct wiring to avoid reverse wiring or short circuits.
Acceleration/Deceleration Time Settings: For applications requiring frequent start-stop cycles, the driver's acceleration/deceleration time needs to be adjusted. Too short a time may cause loss of synchronization, while too long a time will affect efficiency. Typical values are 100-500ms, but specific adjustments should be made based on load inertia.
Protection Function Settings: Enable overcurrent, overheat, and undervoltage protection.
