QX-2H504A 2-phase stepper driver
QX-2H504A 2-phase stepper driver,is the all-digital stepper driver. It uses servo control theory and the optimized control calculation. It has no concepts of “beat” and “subdivision” of the traditional driver. No matter how many steps are set, the motor current is always the accurate sine current instead of current step. That is why the stepper motor has good performance, stability, and low-speed mute and extremely low heat productivity.
Current waveform diagram
The following are current waveform pictures of QD-2H811A and division driver tested under the same condition. Pictures are taken by the oscilloscope without any amendment.
Easy to use
For the conventional use of the drive, the parameters are not set, the output value of these parameters can be used, and for some special use requirements, these parameters can be changed to meet different requirements.

Usually default parameters can normally work. When special application is needed, some parameters can be changed. Parameters include, 1. single/dual pulse (default: single pulse), 2. EN port function (default: off-line), 3. Motor direction (default direction), 4. Lock current percentage (default: 50%), 5. Lock time (default: 1s). If set parameters, before power on the driver, set sw1-4=1111.
