High-performance 4-axis stepper motor driver with pulse direction control. Supports power supply voltage of 12-48VDC and high current up to 6A, suitable for driving 86 motors with external forced heat dissipation. Offers 8-speed options and includes automatic over-current and over-voltage protection functions. Compact size with low heat generation and high power efficiency. Driver interface includes power supply, stepper motor, pulse control, input/output, and bus interfaces, with customizable current and interpolation parameter settings. The driver is a high-performance 4-axis stepper motor driver that supports pulse direction control. It has the advantages of strong anti-interference ability, good stability, low cost, etc. It also has the advantages of small size, low heat generation and high power. The driver interface contains five groups of interfaces, including power supply interface, stepper motor interface, pulse control interface, input and output interface, and bus interface. The optional values of current parameter are 0.5A, 1A, 1.5A, 2A, 2.5A, 3A, 3.5A, 4A, 4.5A, 5A, 5.5A, 6A. The optional values of interpolation parameter are 2, 4, 8, 16, 32, 64, 128, 256.
