The LeanMotor DM860H is a fully digital stepper driver developed with advanced DSP control algorithm based on the latest motion control technology. It is easy to use and it can be used to drive 2-phase nema 34 hybrid stepper motors smoothly with less heat and noise. It works with 24-80VAC or 24-110VDC voltage and can provide max 7.2A peak current. The system achieves exceptional smoothness, delivering optimal torque while eliminating mid-range instability. Its automatic motor identification and parameter configuration enables quick setup with different motors. Compared to traditional analog drives, the DM860H operates with lower noise, less heat generation, and smoother movement. These features make the DM860H ideal for high-performance applications.


DM860H Driver Features:

1. Average current control, 2-phase sinusoidal output current drive

2. 8 channels output phase current setting

3. Offline command input terminal

4. High hording torque under high speed

5. High performance, low price

6. Opto-isolated signal I/O

7. Overvoltage, under voltage, overcorrect, phase short circuit protection

8. 15 channels subdivision and automatic idle-current reduction

9. Motor torque is related with speed, but not related with step/revolution

SW4: ‘OFF’ is with half-current function; ‘ON’ is without half-current function.

Half-current function means that after 500ms of no stepping pulse, the driver output current is automatically reduced to 70% of the rated output current, which is used to prevent the motor from heating up.

Nema 34 Digital Stepper Driver Manual:


1, Q: The motor does not turn and no holding torque:

     A: ① check whether the power line is connected to the wrong voltage is too low, need to increase the voltage or correct the power line

         ② check whether the motor wiring is correct, if not correct motor wiring. Check if the motor wiring is correct, if not, correct the motor wiring.

         ③ Whether the enable signal is valid, resulting in the motor does not work.

         ④ Is the subdividing parameter correct?

         ⑤ Is the current parameter correct?


2、Q:Motor does not rotate but has holding torque:

      A: ① The phase sequence of motor wires is wrong, need to swap any two wires.

          ② Pulse signal input is wrong, need to check the pulse wiring.


3、Q: The motor torque is too small:

      A: ① Phase current setting is too small, need to set the phase current corresponding to the motor.

          ② acceleration is too fast, reduce the acceleration value

          ③ motor blocking, need to rule out mechanical problems

          ④ drive and motor mismatch, need to replace the appropriate drive


4、Q:Motor steering error:

      A: ① motor line phase sequence is wrong, need to swap any two wires

          ② motor line has a broken circuit, check and connect the right


5、Q:The alarm indicator light is on:

     A: ① Is the motor wire connected incorrectly

         ② Whether there is over-voltage and under-voltage conditions

         ③ Motor or driver is damaged


6、Q:Motor acceleration blocking:

     A: ① short acceleration time

         ② motor torque is too small

         ③ Low voltage or current
