Connector Pins    Configurations
Pin Function
Details
PUL +,PUL-
Pulse signal, PUL+ is the positive end of pulses input pin
PUL- is the negative end of pulse input pin
DIR+,DIR-
DIR signal: DIR+ is the positive end of direction input pin
DIR- is the negative end of direction input pin
ENBL+
Enable signal:  ENBL+ is the positive end of direction input pin. This signal is used for enabling/disabling the driver. High level for enabling the driver and low level for disabling the driver.
ENBL-
ENBL- is the negative end of direction input pin. Usually left unconnected (enabled)
2) Pins wiring diagram:
PC’s control signals can be active in high and low electrical level. When the high electrical level is active, all control negative signals will be connected together to GND. When low electrical level is active, all control positive signals will be connected together to public port. Now give two examples( Open collector &PNP), please check them:
Note: When VCC=5V, R=0
When VCC=12V, R=1K, ＞1/8W
When VCC=24V, R=2K,＞1/8W
R must connect in the control signal part .
3.Function choice ( Using DIP pins to achieve this function)
1) Micro step resolution is set by SW 5,6,7,8 of the DIP switch as shown in the following table:
2) Standstill current setting
SW4 is used for this purpose. OFF meaning that the standstill current is set to be half of the selected dynamic current and ON meaning that standstill is set to be the same as the selected dynamic current.
3) Output current setting:
The first three bits (SW 1, 2, 3)of the DIP switch are used to set the dynamic current. Select a setting
Closest to your motor’s required current

4) Semi-flow function:
Semi-flow function is that there is not step pulse after200 ms, the driver output current automatically reduced to 40% of rated output current, which is used to prevent motor heat.

5. Mechanical Specification:
To have 20mm of space around ,cannot be placed next to other heating devices. What’s more, avoid dust, oil mist, corrosive gas, heavy humidity and high vibration. (Unit=mm)
6. Adjustment of troubleshooting
1) , the status on light’s indication
PWR: green, normal work light.
ALM: red, failure light, the motor with phase short-circuit, overvoltage and under-voltage protection.
2) Troubles
Alarm indicator
Reasons
Measures
LED off turn
Wrong connection for power
Check wiring of power
Low-voltages for power
Enlarge voltage of power
Motor doesn’t run, without holding torque
Wrong connection of stepper motor
Correct its wiring
RESET signal is effective when offline
Make RESET ineffective
Motor doesn’t run, butmaintains holding torque
Without input pulse signal
Adjust PMW & signal level
Motor runs wrong direction
Wrong wires’ connection
Change connection for any of 2 wires
Wrong input direction signal
Change direction setting
Motor’s holding torque is too small
Too small relative to current setting
Correct rated current setting
Acceleration is too fast
Reduce the acceleration
Motor stalls
Rule out mechanical failure
Driver does not match with the motor
Change a suitable driver
7. Driver wiring
A complete stepper motor control system should contain stepper drives, DC power supply and controller (pulse source). The following is a typical system wiring diagram
