Overview of CWD556-A :

The CWD556-A is a new generation digital 2-phase stepper motor driver, based on a 32-bit DSP processor, combination of the anti-resonance, low noise, micro-step and low temperature rise technology significantly improve the performance of the stepper motor, has low noise, small vibration, low temperature rise and high-speed torque. The driver CWD556-A use online adaptive PID technology, without manual adjustment can be automatically generated optimal parameters for different motors, and achieve the best performance. Supply voltage range from 24VDC to 50VDC, suitable for driving various 2-phase hybrid stepping motors which phase current below 5.6A. The microstep can be set from full step to 40000steps/rev and the output current can be set form 2.1A to 5.6A; with automatic idle-current reduction, self-test, overvoltage, under-voltage and over-current protection.

Features of CWD556-A:

Applications of CWD556-A:

Suitable for a variety of large-scale automation equipments and instruments. For example: labeling machine, cutting machine, packaging machine, plotter, engraving machine, CNC machine tools and so on. It always performs well when applied for equipment which requires for low-vibration, low-noise, high-precision and high-velocity

Current Setting of stepper motor driver CWD556-A

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.
