Driver Functions Descriptions:
| Driver function | Operating instructions |
| Output current setting |
Users can set the driver output current by SW1-SW3 three switches. The setting of the specific output current, please refer to the instructions of the driver panel figure. |
|
Microstep setting |
Users can set the driver Microstep by the SW5-SW8 four switches. The setting of the specific Microstep subdivision, please refer to the instructions of the driver panel figure. |
|
Automatic half current function |
Users can set the driver half flow function by SW4. "OFF" indicates the quiescent current is set to half of the dynamic current, that is to say, 0.5 seconds after the cessation of the pulse, current reduce to about half automatically. "ON" indicates the quiescent current and the dynamic current are the same. User can set SW4 to "OFF", in order to reduce motor and driver heating and improve reliability. |
|
Signal interfaces |
PUL+ and PUL- are the positive and negative side of control pulse signal; DIR+ and DIR- are the positive and negative side of direction signal; ENA+ and ENA- are the positive and negative side of enable signal. |
|
Motor interfaces |
A+ and A- are connected to a phase winding of motor; B+ and B- are connected to another phase winding of motor. If you need to backward, one of the phase windings can be reversed. |
|
Power interfaces |
It uses DC power supply. Recommended operating voltage is 24VDC-80VDC, and power consumption should be greater than 350W. |
|
Indicator lights |
There are two indicator lights. Power indicator is green. When the driver power on, the green light will always be lit. Fault indicator is red, when there is over-voltage or over-current fault, the red light will always be lit; after the driver fault is cleared, if re-power the red light will be off. |
|
Installation instructions |
Driver dimensions:150×99×48mm, please refer to dimensions diagram. Please leave 10CM space for heat dissipation. During installation, it should be close to the metal cabinet for heat dissipation. |

More Driver for choosing:
In order to improve the performance of stepper motors, subdivision drives have been widely used. The principle of the subdivision drive is to change the angle of the synthesized magnetic field by changing the magnitude of the phase current, so that a step angle can be subdivided into multiple steps. This driver is mainly used for stepper motors.
