An overview of the

Ybd1-0522g3 is an equal-angle constant-torque subdivision type universal stepper motor driver. The internal circuit similar to servo control principle is adopted. This circuit can make the motor run smoothly, almost no vibration and noise, and the motor torque is much higher than two-phase and five-phase hybrid stepper motor at high speed. The driving voltage of the driver is 110V~220V AC, the adaptive current is 2.2A~5.2A, the outer diameter is 57mm, 86mm, 110mm and 130mm of various types of three-phase hybrid stepping motor. The positioning accuracy of the drive is up to 60,000 steps/revolution.

The characteristics of：

• Using vector control and subdivision control technology, the operation stability, noise, vibration, heating and other aspects of the traditional driver are greatly improved;

• Photoelectric isolation signal input/output;

• Set 16-step constant torque subdivision with the highest resolution of 60000 steps/RPM:

• Maximum response frequency up to 200KppS;

• When the step pulse stops for more than 1s, the coil current automatically decreases to half of the set current:

• The driving current is adjustable from 2.2a/phase to 5.2a/phase in 16 grades.

• Single power input, voltage range AC110-220V;

• Fault protection: short circuit, overheating, over current, under voltage, over voltage protection;

• Phase memory function (note: after the input pulse stops for more than 5s, automatic memory of the motor phase, heavy

• Automatically restore motor phase when new power-on or MF signal changes from valid to invalid) :

• The drive volume is 177×108×70(mm3).
