Digital Stepper Driver OK2D872 1.4-5.6A 24-110VDC,18-80VAC for NEMA 23 NEMA 24 NEMA 34 Stepper Motor
OK2D872T is a digital two-phase stepper driver controlled by the 32-bit ARM processor. This digital driver has peripheral subdivision, current, and auxiliary function dial codes, which users can freely set according to their needs.
Features:
Built in high subdivision, low vibration, low heat generation, and stable low-speed operation;
Current vector control, high current efficiency;
Built in acceleration and deceleration control to improve smoothness of start stop;
Single and double pulse control modes can be selected;
Memory of motor operating position;
Input signal differential optocoupler isolation, compatible with 5V~24V;
Overcurrent protection, overvoltage protection;
Automatic detection, flexible selection of pulse edge counting method;
Green light indicates operation, while red light indicates protection or offline;
The SW1-3 current dial settings are shown in the table below.
