Function Description
Functions	Operation Instructions
Signal Interface	PUL	PUL+ is the positive end of the control pulse signal PUL- is the negative end of the control pulse signal
	DIR	DIR+ is the positive end of directional signal DIR- is the negative end of directional signal
	ENA	ENA+ is the positive end of enabling signal ENA+ is the negative end of enabling signal
Motor Interface	A	A+ is connected with the positive end of the A phase winding of the stepping motor A- is connected with the negative end of the A phase winding of the stepping motor
	B	B+ is connected with the positive end of the B phase winding of the stepping motor B- is connected with the negative end of the B phase winding of the stepping motor
	When the A and B two phase windings are switched, the motor direction is reversed
Indicator Light	1. The green light is the power indicating lamp. When the drive is powered on, the green light is always on. 2. The red light is the fault indicating lamp. When the overvoltage and overcurrent faults occur, the trouble lamp is always on.
Note: The default input signal is 5V pulse signal. When 24V input signal is required, please in series with1.8-2kΩ resistance.

Tips: what circumstance is offline signal of hybrid stepper driver generally used?
When the offline signal FREE is low level, the current output to the motor by the driver is cut off and the motor rotor is at free state (offline state). as for some automatic device, under the circumstance that the power of drive is not disconnected, it is required to directly rotate the motor shaft (manual mode) to put the signal FREE on the bottom, so that the motor is at offline state. As for manual operation or adjustment, after manual completion, the signal FREE can be put in higher position to realize continuous automatic control.

Using this driver to operate a Nema 17 stepper motor at 48V 3A

I am currently using this driver to operate a Nema 17 stepper motor at 48V 3A. I have been using arduino shields for stepper motors, but this is so much easier and better.
