Overview
The DM556 is a new generation high-performance digital stepper driver based on DSP with an advanced control algorithm. The motors driven by DM556 can run with much lower noise and much less vibration than other drivers in the market. The DM556 possesses the feature of lower noise, lower vibration, and lower heating. The DM556’s voltage is DC 20V-50V. It is suitable for all the 2-phase hybrid stepper motors whose current is less than 5.6A. There are 15 kinds of micro step of DM542. The maximum step number of DM556 is 25000steps/rev (microstep is 1/128 ). Its current range is 1.4A-5.6A, and its output current has 8 stalls. DM556 has automatic semi-flow, over-voltage, under voltage, and over-current protection functions.
It is more ecomomical than DM542 and other drivers. What is more, it can match with NEMA17, NEMA23 and NEMA34 stepper motors.
And it is widely used in CNC systems.
Common indicator of 2 phase stepper motor driver
| Phenomenon | Reason | Solution |
| The red indicator is on. | 1. A short circuit of motor wires. | Inspect or change wires |
| 2. The external voltage is over or low than the driver’s working voltage. | Adjust the voltage to a reasonable range |
| 3. Unknown reason | Return the goods |
What is driver segmentation? What is the relation between the speed of stepping motor and pulse frequency?
Due to the unique structure of the stepping motor, it is marked with "inherent step Angle of the motor" when leaving the factory (for example, 0.9°/1.8°, indicating that the rotation Angle of each step of the half-step is 0.9° and that of the whole step is 1.8°).
However, in many precision control and occasions, the whole step Angle is too large, affecting the control accuracy, and vibration is too large, so many steps are required to complete a motor natural step Angle, which is the so-called subdivision drive, the electronic device that can achieve this function is called the subdivision driver.
Applications of stepper motor driver
It 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. It always performs well when it is used in equipment which requires for low-vibration, low-noise, high-precision and high-velocity.
