DM3722 uses 32-bit DSP processor as the operation core, and is located in a high-tech level universal fully isolated three-phase high-voltage high-power stepping motor driver. It uses more advanced software algorithms than AC servo combined with powerful three-phase power to push the unit. The performance is high-speed and high-torque output, low noise, low vibration, and low heat generation. Due to the use of built-in dynamic subdivision technology, even under the condition of low subdivision, it can achieve the effect of high subdivision, low, medium and high speed The operation is very stable and the noise is super small. The driver has the functions of motor parameter learning, automatic setting of control parameters, and fine-tuning and adaptive parameter change during operation. It can automatically generate operating parameters for different motors and give full play to the performance of the motor.

● Fully isolated, safer and more reliable, avoiding VLSI DSP processors from working in hot ground with random interference.

● Strong anti-interference ability, little external interference, and can work with high-power inverter groups and high-power servo groups.

● Built-in ultra-high dynamic subdivision and ultra-low vibration noise can replace servo for some simple applications.

● Parameter Theory Calculation and Learning Correction and Fast Self-tuning Technology

● Intelligent current control improves dynamic Q value and greatly reduces motor heating

● Improved PWM control algorithm and whole machine low power consumption technology make the motor and driver generate less heat.

● At rest, the current is automatically halved, and the half-current delay software can be set. The full-current switch to half-current has no obvious noise and vibration.
