Stepper Motor Driver
Performance
Electrical properties (ambient temperature Tj = 25 º C hours)
advanced bipolar constant-current chopper drive technology.
l High-speed torque output increased 40%, to avoid the lost-step (no-load start-up speed up to 300 ~ 420r/min) maximum speed of up to 3500 r / min.
l Flexible output current set, fit different types of motors, with automatic half-current function at the same time, reduce motor heating.
l the largest sub-set 128 to meet a variety of mechanical transmission and does not affect its output torque.
l input pulse mode is set and high-low setting, easy to use.
l protection Full: Enter the power supply overvoltage, undervoltage, output overcurrent, white short, drive high temperature alarm protection.
l electric low-speed non-creeping phenomenon, noise, non-resonant region.

Function and Use
l Power Interface DC +, DC -
DC 24 ~ 50DC, usually a linear power supply (see Appendix: linear power supply schematic) power supply, the user should be noted that the filtered rectified power supply ripple voltage, not more than 50VDC, so as to avoid damage to the drive, linear power supply rated output current should be larger than the current drive to set 60%. When using switching power supply should be attention to the nominal rated output current, to choose a match with the motor phase current switching power supply. General, the higher the supply voltage, the motor torque output greater steps to avoid the phenomenon of high-speed lost, but also lead to increased low-speed vibration, as well as fever, should be used with the mechanical requirements of a reasonable adjustment under the on-site power supply voltage, we adopted the test concludes that the most ideal voltage range of between 30VDC ~ 40VDC.
Should pay special attention to input power wiring polarity, DC + for the power supply cathode; DC-for power, the wrong cable can cause damage to the drive!
In order to meet electromagnetic compatibility requirements drive is recommended to use the company-driven design of DC power supply.
l Set output current
The Driver Design 8 file output current choices and drive the encoding switch (SW1 SW2 SW3) setting, the current size to the maximum nominal. SD-2H044MA type drives available 4.25A maximum output current, the current setting resolution of 0.41A. Coding switch (SW1 SW2 SW3) for each combination of a state represents a current value of the output settings, reference the table below:
