Driver Function Description
| Driver function | Operating instructions |
| Micro step fine score setting | The microstep division of the driver is set by three dip switches from SW6 to SW8, with a total of 8 microstep divisions. User SettingsWhen setting the microstep division, the driver should be stopped first. For the specific setting of the microstep division, please follow the instructions on the driver panel |
| Output current setting | The output current of the driver is set by four dip switches from SW1 to SW4, and there are a total of 16 output current Settings. "Specific inputFor the setting of the output current, please refer to the instructions on the driver panel |
| Automatic semi flow function | Users can set the automatic half-current function of the driver through the SW5 switch. "OFF" indicates that the static current is set to half of the dynamic current, and "ON" indicates that the static current and dynamic current are the same.In general applications, SW5 should be set to OFF to reduce the heat generation of the motor and driver and improve reliability. Pulse trainAbout 0.3 seconds after stopping, the current automatically decreases by 50%(the actual value is 55%), and the heat generation theoretically reduces by 65% |
| Signal interface | PUL+ and PUL- are the positive and negative terminals of the control pulse signal. DIR+ and DIR- are the positive and negative ends of the direction signal respectively:ENA+ and ENA- are the positive and negative terminals of the enable signal |
| Motor interface | U,V, and W correspond to the motor winding group. By swapping any two of the three winding wires, the direction of the motor can be changed |
| Power interface | It is powered by a DC power supply, with a working input voltage range of 20V to 50VDC. The recommended voltage power supply is 36VDC, and the power supply capacity should be greater than 100W |
| Indicator light | The drive has two indicator lights, red and green. Among them, the green light is the power indicator light. When the driver is powered on, the green light remains constantly on. The red light is the fault indicator light. When overvoltage or overcurrent faults occur, the fault light remains on constantly. After the fault was cleared, the red light went out. When a drive malfunctions, the fault can only be cleared by re-powering and re-enabling it |
| Installation instructions | The external dimensions of the driver are 117 x 78 x 34mm, and the installation hole spacing is 111mm. It can be installed either horizontally or vertically (vertical installation is recommended). When installing, it should be tightly attached to the metal cabinet to facilitate heat dissipation |
