BF3DM860 Nema34 86mm Hybrid 3 Phase Stepper Motor Driver

BF3DM860 is a new generation of high-performance digital three-phase stepping motor driver, using 32-bit DSP technology and the latest digital PID control algorithms, embedded micro-fractional control technology significantly reduces the noise and vibration of the motor operation, with low noise, low vibration, low temperature rise and other characteristics. The voltage of the driver is 20V-80V AC, and it is suitable for various types of three-phase hybrid stepping motors with current below 6.0A. There are 16 kinds of micro-stepping subdivisions, and the maximum subdivision is 40,000 pulses/revolution; the reference working current range is 2.0A-6.0A, and the output current has 8 grades in total; it has the protection functions of automatic half-current, self-checking, over-voltage, under-voltage, and over-current, and so on.

Features:
● Output current setting
● Micro-step fine fraction setting
● Automatic half-current function
● Signal interface
● Motor interface
● Power supply interface
● Fault indicator

Suitable for all kinds of large-scale automation equipment and instruments. For example: labeling machines, cutting machines, packaging machines, plotters, engraving machines, CNC machine tools, etc. It is particularly effective in equipment where users expect low cost, low vibration, low noise, high precision, and high speed.

Description:

The Besfoc 3DM860 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.



Application areas: 

suitable for a variety of large-scale automation equipment and instruments. For example: labeling machines, cutting machines, packaging machines, plotters, engraving machines, CNC machine tools and so on. In the user expects low cost, low vibration, small noise, high precision, high speed equipment in the effect is particularly good.

Nema 34 3-Phase Stepper Motor 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?


2Q：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.


3Q: 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


4Q：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


5Q：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


6Q：Motor acceleration blocking:

     A: ① short acceleration time

         ② motor torque is too small

         ③ Low voltage or current
