50 VDC Two Phase Digital Stepper Motor Driver 280g HJD5056S

Digital 2 Phase Stepper Motor Driver 24 - 50 VDC 280g Light Weight

      HJD5056S is a new digital stepper motor driver by HEJIEMOTOR. It adopts the latest 32-bit DSP digital processing technology. The drive control algorithm adopts advanced variable current technology and advanced frequency conversion technology. The driver has small heating, small motor vibration and stable operation. Users can set any subdivision within 200 ~ 51200 and any current value in the rated current to meet the application needs in most occasions. Thanks to the built-in micro-subdivision technology, the subdivision effect can be achieved even under the condition of low subdivision. The operation is smooth and the noise is ultra-small under low, medium and high speed. The driver integrates the parameter auto-adjust function, which can automatically generate optimal operating parameters for different motors to maximize the performance of the motor. Suit for NEMA23 AND NEMA34 stepper motor.

Power supply options:
HJD5056S can working normally in the specified range of voltage, and use non-regulated DC power supply is best, also can use transformer reduction + bridge rectifier + capacitor filter. However,should notice that voltage ripple peak value after rectifier should not exceed its maximum specified voltage. It is recommended that users use DC voltage lower than the maximum voltage to supply power and avoid the fluctuation of power grid beyond the working range of driver voltage.
If using a regulated switching power supply, be aware that the output current range of the switching power supply needs to be maximized.
Please note:
1) When wiring, pay attention to the positive and negative poles of the power supply.
2) Best use non-regulated power supply;
3) When using non-regulated power supply, the power supply current output capacity should be greater
than 60% of the driver set current;
4) When use regulated switching power supply, the output current of the power supply should be greater
than or equal to the working current of the driver;
5) To reduce costs, two or three drives can share a power supply, but should ensure that the power supply is
large enough.

Motor matching:
HJD5056S can be used to drive 4,6,8-wire two-phase, four-phase hybrid stepper motor, step angle of 1.8 degrees and 0.9 degrees are both applicable. When selecting a motor, it is mainly determined by the torque of the motor and the rated current. The size of the torque is mainly
determined by the motor size. The motor torque is large for large size; and the current is mainly related to the inductance, small inductance motor has high speed performance, but the is current larger.

Driver FAQ:
1)What is a stepper motor and stepper driver?
Stepper motor is a special motor for precise control of speed and position. It rotates at a fixed angle (called "step angle") step by step, so called stepper motor. It is characterized by no cumulative error. It receives every pulse sent from the controller and drives the motor at a fixed angle by the driver. Therefore, it is widely used in various open-loop control.
The stepper driver is a kind of power amplifier that can make the stepper motor operation. It can convert the pulse signal from the controller into the power signal of the stepper motor. The speed of the motor is proportional to the pulse frequency, so that control pulse frequency can be precisely adjusted speed, and control the pulse can precise positioning.

2)What is the subdivision of the driver? What is the relationship between the speed and the pulse frequency?
Stepper motor due to its own unique structure, the factory are marked with "motor inherent step angle" (such as 0.9° / 1.8 °, means half-step work every step of the turn angle is 0.9 °, the whole step is 1.8 ° ). However, in many precise control and occasions, the whole step angle is too large, which affects the control accuracy and the vibration is too large. Therefore, it requires many steps to complete an inherent motor step angle, which is called subdivision drive and the electronics which can realize this function are called subdivided drivers.

V:Motor speed(r/s) P:Pulse frequency(Hz)
θe:Motor inherent step angle m:Subdivision (whole step is 1, half step is 2)

3) What are the advantages of subdivision driver?
● Increasing step uniformity by reducing the step angle,so that can improve the control accuracy.
● Can greatly reduce the motor vibration, low-frequency oscillation is the inherent characteristics of the stepper motor, using of subdivision is the best way to eliminate it.
● can effectively reduce the torque ripple, increase the output torque.
These advantages are generally recognized by the user, and bring them benifits, so we recommend using subdivision driver.

4) Why does my motor only operate in one direction?
● The direction signal may be too weak, or the wiring polarity is wrong, or the signal voltage is too high, burnout direction current limiting resistor.
● Pulse mode mismatch, signal is pulse / direction, driver must be set to this mode; drive must be in the same mode if the signal is CW / CCW (double pulse mode), or the motor will run in only one direction.
