Function Description
FunctionsOperation Instructions
Signal InterfacePULPUL+ is the positive end of the control pulse signal PUL- is the negative end of the control pulse signal
DIRDIR+ is the positive end of directional signal DIR- is the negative end of directional signal
ENAENA+ is the positive end of enabling signal ENA+ is the negative end of enabling signal
Motor InterfaceAA+ 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
BB+ 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 Light1. 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: 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.
