Connection port and indicator light:
1 PUL+ (+5V) Pulse signal: when single pulse control mode, the pulse control signal, the pulse rise along is effective, when  double pulse control mode, the positive pulse signal, pulse rise along is effective. Single / double pulse control mode set by SW1
2 PUL-
3 DIR+ (+5V)Directional signal: single pulse control mode for high / low level signal, double pulse control for the reverse pulse signal. Pulse rising edge. Single / double pulse control mode set by SW1
4 DIR-
5 ENA+ (+5V)Enable signal: this input signal is used to enable / disable. High level enable, low power usually drive can not work, do not need to be left vacant.
6 ENA-
7 AC1 AC and DC power supply (DC is not distinguished as positive or negative)

8 AC2 AC and DC power supply (DC is not  distinguished as positive or negative)
1, according to the motor working state to select the voltage value, the theory of high speed state to choose high voltage
2, power supply range in the DC24V-50V between any value can be, but according to the use of the voltage value of the general motor speed is lower than the 200 to the proposed use of voltage is 24-36VDC, the high speed condition can be appropriately increased, can not exceed 50VDC
3, taking into account the stability of the city power, the maximum value of AC power supply is recommended not to exceed 35VAC
4, When higher than the 36VDC it is better that the driver is installed on the metal casing, to ensure good heat dissipation environment
9 A+: motor is A phase, A+, A-  intermodulation, can change a motor rotation direction
10 A- :motor A phase
11 B+: motor is B; B+, B-  intermodulation, can change a motor rotation direction
12 B-: motor is B phase
13 USE driver power supply indicator, the green light indicates that the system works properly
14 ERR: driver error report indicating lamp, red light indicates that the system is not working properly, the driver works when the red light goes out.

Package included:
- 1 x Stepper Motor Driver
