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

Tips: Current comparison chopper drive method for stepper motor
Current comparison chopper drive is to convert the stepper motor’s winding current into a certain percentage of voltage, which is compared with the preset value output by a D / A converter, the result of which comparison is used to control the switch of power tube for the purpose of control of the winding phase current.
Advantages: To make motion control simulate characteristics of sine waves, greatly improving performance, relatively small speed and noises, higher subdivision able to be used, current popular control method.
Disadvantages: The circuit is more complex. It is difficult to control circuit interference which should be consistent with theoretical requirements. Vibration is easy to occur. In the control of formation of crests and troughs of sine waves, high-frequency interference is easily led to, which further leads to heating of drive elements or aging because of excessively high frequency. That is also the main reason why red light protection tends to occur when many drives are used for more than one year.
