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:
High-performance, Low price
Micro-step
Automatic idle-current reduction
Optical isolating signals I/O
Max response frequency up to 200Kpps
Low temperature rise, smooth motion
Online adaptive PID technology
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

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.
