Our DM860D is a high-performance digital stepper driver based on DSP and PID control algorithm with microstep control technology. The stepper motors driven by DM860D can run with much smaller noise and much less vibration than other drivers in the market. The DM860D possess the feature of lower noise, lower vibration, and lower heating. Its voltage is DC24V~80V or AC20V~60V. It is suitable for all the 2-phase stepper motor whose current is less than 7.2A. There are 16 kinds of microstep of DM860D. The maximum step number of DM860D is 51200 steps/rev (microstep is 1/256 ). Its current range is 2.4A~7.2A, and its output current has 8 stalls. DM860D has automatic semi-flow, over-voltage, under voltage and over-current protection function. Our DM860D stepper driver can be applied in a variety of small scale automation equipment and instruments, such as labeling machine, cutting machine, packing machine, drawing machine, engraving machine, CNC machine and so on.

Users can set the driver half flow function by SW4. "OFF" indicates the quiescent current is set to half of the dynamic current. "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.

Indicator Lights |
There are two indicator lights. Power indicator is green. When the stepper 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. |
