Driver Functions Descriptions:

Driver Function Operating Instructions
Output Current Setting Users can set the driver ouput current by SW5-SW7 three switches. The setting of the specific output current, please refer to the instructions of the driver panel figure.
Microstep setting Users can set the driver Microstep by the SW1-SW3 three switches. The setting of the specific Microstep Subdivision, Please refer to the instructions of the driver panel figure. SW4 and SW8 is vacancy, they do not need to be adjusted.
Signal Interfaces PUL is the setting pulse input, DIR is the stepper motor direction input, OPTO is the power supply for signal port+5V, ENA is the motor free input.
Motor Interfaces A+ and A- are connected to a phase winding of the motor; B+ and B- are connected to another phase winding of the motor. If you need to backward, one of the phase windings can be reversed.
Power Interfaces It uses DC power supply. Recommended operating voltage is 18VDC-40VDC, and power consumption should be greater than 100W
Installation Instructions Driver dimensions:117*71*35mm, Please refer to dimensions diagram. Please leave 10cm spce for heat dissipation. During installation, It should be close to the metal cabinet for heat dissipation.


Signal Interface Details:

The internal interface circuits of the driver are isolated by the opt coupler signals,

R in the figure is an external current limiting resistor. The Connection is differential.

And it has a good anti-jamming performance.
